Tsunami Drill (IOWave14) Manual

1. Background

The December 26, 2004 Indian Ocean event has raised awareness of tsunami peril in the

Indian Ocean region and demonstrated the extensive damage and disruption to human life,

livelihood, infrastructure and economic activities that such an event can cause. The recent

major tsunami on March 11, 2011 in Japan is a stark reminder of the unpredictable danger

posed by tsunamis.

The characteristics of a tsunami such as fast-onset and unpredictability regarding when the

next tsunami will hit and where, make Tsunamis unique from other hazards. However, when

it does happen, it impacts in severe way with little notice and therefore little time to prepare.

This puts a tremendous responsibility on countries like India where 26% of population live

within 100 Km from the shoreline, to prepare ahead of time through planning, development

of agreed-upon Standard Operating Procedures and practice through drills and exercises.

Minimizing future losses to the nation from tsunamis requires persistent progress across the

broad spectrum of efforts: risk assessment, detection and forecasting, disaster mitigation

operations and community awareness and education. Sustained efforts in all these areas will

be needed for communities to prepare for an event through effective emergency response

plans and regular community awareness programmes. Being prepared, including regular

testing, conducting risk assessments and evaluation of the system will enable people to

become more resilient to hazards like tsunami.

This manual provides information on how to plan, conduct and evaluate Tsunami drills. It

has been designed for use by national/state/local disaster management offices who will

participate in these drills to provide a range of practical advice and templates for effective

implementation of the tsunami drill.

2. Indian Tsunami Early Warning System

Following the December 26, 2004 event, India started its own interim tsunami warning

services in the first quarter of 2005 to issue/share only seismic information with the national

authorities. The interim services were followed by setting up of a state-of-the-art Indian

Tsunami Early Warning System (ITEWS) at the Indian National Centre for Ocean

Information Services (INCOIS), Hyderabad, under the Ministry of Earth Sciences (MoES),

Govt. of India. The ITEWC was inaugurated and dedicated to nation on October 15, 2007 as

the Indian National Tsunami Warning Centre.

The tsunami centre is having all the necessary computational and communication

infrastructure that enables reception of real-time data from wide range of sensors, analysis of

the data, generation and dissemination of tsunami advisories following the SOP. The centre

operates on 24x7 basis.

2.1. Infrastructure

The ITEWS comprises a real-time network of seismic stations, tsunami buoys and tide

gauges to detect tsunamigenic earthquakes and to monitor tsunamis. All the real-time data is

collated at INCOIS in collaboration with various national organizations such as the Indian

Meteorology Department (IMD), National Institute of Ocean Technology (NIOT), Survey of

India (SOI), as well as international sources.


2.2. Capability

The centre is able to detect globally occurring earthquakes, of magnitude greater than 5.0

within five to ten minutes of the event. A database of pre-run open ocean propagation

scenarios has been created using TUNAMI N2 model. Arrival times and wave heights at

several coastal forecast points for each scenario are stored in a database. Travel times and

Surge heights on 30 m bathymetry are interpolated to get the values at Coast enabling

provision of tsunami bulletins at a district level. Whenever an earthquake occurs, the closest

scenario to the event is extracted from the scenario database based on magnitude and

hypocenter location to identify the regions at risk.

2.3. DSS and SOP

A Decision Support System (DSS) is a set of rules to be followed for issue of tsunami

bulletins. These rules are appropriately coded in the form of software-rules-engine that

automatically generates bulletins by accessing the real-time data from the observation

network as well as the model scenario database. The Standard Operating Procedure (SOP) is

the set of routine activities to be followed by the staff at the tsunami warning centre for

observation, evaluation, confirmation, and dissemination of bulletins. The DSS has been

built so as to enable the centre to pick up the closest scenario from the scenario database for

generating tsunami advisories, at the time of occurrence of event. Real-time water level data

enables confirmation or cancellation of a tsunami.

ITEWC services for an earthquake event commence whenever earthquakes are recorded with

magnitudes ≥ 6.5 within Indian Ocean and magnitudes ≥ 8.0 outside Indian Ocean. Duty

officers respond immediately and begin their analysis of the event. The analysis includes

automatic and interactive processes for determining the earthquake's epicenter, depth, and

origin time, as well as its magnitude.

The criteria for generation of different threat types (WARNING / ALERT / WATCH) for a

particular region of the coast are based on the available warning time (i.e. time taken by the

tsunami wave to reach the particular coast). The threat criteria are based on the premise that

coastal areas falling within 60 minutes travel time from a tsunamigenic earthquake source

need to be warned based solely on earthquake information, since enough time will not be

available for confirmation of water levels from tsunami buoys and tide gauges. Those coastal

areas falling outside the 60 minutes travel time from a tsunamigenic earthquake source could

be put under a Alert/Watch status and upgraded to a Warning/Alert only upon confirmation

from water-level data.

The criteria for considering an area under different Threat level (WARNING / ALERT /

WATCH) are as follows:

Table 1: Threat Level Status Criteria

Pre-run Model Scenario Results

WATCH 0.2 to 0.5 WATCH 0.2 to 0.5

WATCH 0.5 to 2 ALERT 0.5 to 2

ALERT > 2 WARNING > 2

Threat Status

EWA (m) Threat Status EWA (m)

ETA > 60 mins

ETA < 60 mins


2.4. Dissemination

As per the guidelines issued by the National Disaster Management Authority (NDMA),

ITEWC disseminates all tsunami bulletins to Ministry of Home Affairs (MHA), NDMA,

National Crisis Management Committee (NCMC) and National Disaster Response Force

(NDRF) battalions, National Emergency Operations Centre (NEOC), State Emergency

Operations Centres (SEOC), District Emergency Operations Centres (DEOC), public and

media through all possible modes of dissemination such as SMS, E-mail, Fax, Phone,

Website, FTP, Electronic Display Boards (EDB) and a satellite-based Virtual Private

Network for Disaster Management Support (VPN-DMS), for taking appropriate action.

Wherever public action is needed such as in case of ALERT/WARNING/THREAT

PASSED the information is disseminated to public and media too.

3. International Framework

The UNESCO’s Intergovernmental Oceanographic Commission (IOC) formed the

International Coordination Group for the Tsunami Warning System in the Indian Ocean

(ICG/IOTWS) on July 2005, as a coordinated international response to the 2004 Tsunami

event. The ICG/IOTWS is serving as the regional body to plan and coordinate the design and

implementation of an effective and durable tsunami warning and mitigation system. The

system will be fully owned by the 28 member states of the Indian Ocean Tsunami Warning

System (IOTWS), and is based on international and multilateral cooperation with

governance provided by IOC.

Under the guidance of the ICG/IOTWS, Member States collaborated in the development of

the IOTWS, which was initially tested in the Indian Ocean-wide tsunami warning and

response exercise IOWave09 (October 2009), and which then came into operation

immediately following the subsequent IOWave11 (October 2011) exercise. Since then, the

three Regional Tsunami Service Providers (RTSPs) of Indian Ocean: Australia, India and

Indonesia are providing real-time tsunami products to the National Tsunami Warning

Centres (NTWCs) of the IOTWS Member States. A performance assessment of the RTSPs

conducted during the 9th Session of the ICG/IOTWS in Jakarta, Indonesia (27-30 November

2012) found the RTSP services to be satisfactory. The 9th Session of the ICG/IOTWS

established a Task Team to organize the next Indian Ocean-wide tsunami exercise

(IOWave14) in the second half of 2014.

Indian Ocean-wide tsunami exercises are effective tools for evaluating the readiness of the

IOTWS and for identifying changes that can improve its effectiveness. There have been few

major Indian Ocean tsunamis in the last few years, but the IOTWS must be prepared for the

next major event.

4. Concept of Tsunami Drills

While a tsunami cannot be prevented, its impact can be mitigated through community and

emergency preparedness, timely warnings, effective response, and public education. The

purpose of Tsunami drills is to evaluate the ability of warning centre and national/state/local

disaster offices to respond to a tsunami. The drills not only emphasize the testing of

communications from warning centre to its stakeholders, but also provide an opportunity for

testing national/state/local chains of command and decision-making, including the alerting

and evacuation of people from selected coastal communities. They also provide a prospect to

promote emergency response plans and tsunami preparedness.

The Warning Centre actively participates in Tsunami Drills (Indian Ocean Wave Exercises)

conducted by International Coordination Group for the Indian Ocean Tsunami Warning and

Mitigation System (ICG/IOTWS) of UNESCO.

4.1. IOWave09

The first tsunami drill (IOWave09) was held on October 14, 2009 to coincide with World

Disaster Reduction Day. The IOWave09 exercise was conducted in 2 stages, 1) Tabletop

Exercise- September 14, 2009 and 2) Functional Exercise- October 14, 2009. A total of 18

Member States: Australia, Bangladesh, India, Indonesia, Kenya, Madagascar, Malaysia,

Maldives, Mauritius, Mozambique, Myanmar, Oman, Pakistan, Seychelles, Singapore, Sri

Lanka, Tanzania and Timor Leste participated in the exercise. Some countries such as

Kenya, Indonesia, Sri Lanka, etc executed it down to the community level.

4.1.1 National-level Implementation of IOWave09

At national level, two organizations: the INCOIS and the Ministry of Home Affairs (MHA),

participated in the IOWave09 to test their Standard Operating Procedures (SOP), Decision

Support Systems (DSS), communication and logistical infrastructure and the response

mechanism. In run-up to the actual exercise, INCOIS generated a detailed manual

prescribing the procedures to be followed and the bulletins to be exchanged during the

exercise. This was followed by a table-top on September 14, 2009 with participation of

official from INCOIS and MHA. During the actual exercise on October 14, 2009, INCOIS

sent 14 tsunami bulletins to MHA that provided threat status at district administration level.

The exercise provided an opportunity to evaluate coordination and exchange of time-critical

information during an event between the INCOIS and MHA.


4.2. IOWave11

The IOWave11 exercise, conducted on October 12, 2011, was designed to evaluate and

improve the effectiveness of IOTWS, its operational RTSPs, NTWCs, and National Disaster

Management Organisations (NDMOs), in responding to a potentially destructive tsunami. It

also provided an opportunity for Indian Ocean countries to test their communication

methods, review their SOPs, tsunami emergency response plans and tsunami emergency

preparedness. A total of 22 Member States: Australia, Bangladesh, Comoros, France (La

Reunion), India, Indonesia Kenya, Madagascar, Malaysia, Maldives, Mauritius,

Mozambique, Myanmar, Oman, Pakistan, Seychelles, Singapore, Sri Lanka, Tanzania,

Thailand, Timor Leste and Yemen participated in the exercise. Some countries such as India,

Kenya, Malaysia and Mauritius, etc executed it down to the community level.

The exercise simulated the December 26, 2004 Indian Ocean Tsunami, which was one of the

worst disasters of the 21st century till date. The exercise started at 0630 IST and ended at

1830 IST, lasting about 12 hours of simulation. The post-evaluation showed that most of the

countries/agencies expressed a positive view on IOWave11 Exercise planning, conduct,

format and style.

4.2.1National-level Implementation of IOWave11

At the national level, this was a first-of-its-kind tsunami drill that involved evacuation of the

coastal communities. Disaster Management Authorities of Andaman & Nicobar, West

Bengal, Odisha, Andhra Pradesh, Tamil Nadu, Maharashtra and Lakshadweep, National

Disaster Management Authority, Ministry of Home Affairs, Indian Navy, Indian Coast

Guard, National Disaster Response Force, National Hydrographic Office, Port Authorities

(Chennai, Ennore, Kandla, New Mangalore, Paradeep) and Nuclear Power Stations

(Koodankulam, Madras, Tarapore) participated in the drill. Each agency is learnt to have

taken the drill down to different levels, involving their field units, district-level officials,

mandal-level officials, line departments and public, as appropriate. Authorities executed

village/community level evacuation in Maharashtra (Chowk, Arnada, Palm, Chikle, Varsoli,

Chanje, Murud, Srivardhan, Kasop, Deobad), Odisha (Purnabandha, Narasinghpurpatana,

Pipal, Ramnagar, Nuagaon, Krushnagar) and Puducherry (Pillai Chavadi). A host of last-

mile communication systems such as sms-based alerts, megaphones, etc were used by the

local authorities to alert coastal population.

During the drill, the ITEWC successfully exercised its enhanced decision support system

capable of generating and disseminating national and regional bulletins simultaneously using

SMS, Fax, email, Web & GTS. While the centre has been providing national bulletins since

October 2007, successful participation in this drill marked its graduation to an RTSP for the

entire Indian Ocean region.

4.3. Mock tsunami drill to Andaman & Nicobar Islands (Suraksha Gunj)

Andaman & Nicobar Islands (ANI) are situated right on subduction zone which may cause

major earthquakes followed by tsunamis. A COMMs test and tsunami mock drill were

conducted for Andaman & Nicobar Islanders on November 20 and 22, 2013 respectively.

These events were jointly organised by ITEWC, INCOIS and Directorate of Disaster

Management, Andaman & Nicobar administration. The drill was conducted at two levels i)

communication test for entire ANI and ii) tsunami mock drill for selected communities in

ANI. The mock drill simulated the December 26, 2004 event and ran in real time for 9 hours

period. All the three districts of ANI participated and took it down to community level. As


preparatory to the mock drill, ITEWC, INCOIS also conducted a Standard Operating

Procedure (SOP) workshop to line departments of ANI on September 11, 2013 at Port Blair.

4.4. IOWave14

The forth coming tsunami drill (IOWave14) is scheduled on September 09 & 10, 2014. At

national level INCOIS, in coordination with disaster management offices is planning to

conduct this tsunami drill. The details are provided in Section-6 of this manual.

5. Preparations for the Tsunami Drill

5.1. Communication Tests

As a part of international operations, routine communications tests (COMMs tests) are

carried out to validate the dissemination and reception of tsunami notification messages,

access to website containing bulletins, threat maps and tsunami information tables with wave

arrival and amplitude details. ITEWC actively participates and conducts such

communication tests at national level.

ITEWC had conducted 3 national level communication tests so far. The first COMMs test

was conducted on June 15, 2011, second on September 14, 2011 and the third on June 12,

2013. Recipients from different organizations like the National Disaster Management

Authority (NDMA), Battalions of National Disaster Relief Force (NDRF), Coastal State

disaster relief commissioners, Indian Navy, Coast Guard, Disaster Management

Administrators from Andaman & Nicobar Islands, Ports authorities, Nuclear power plants,

etc. actively participated in these COMMs tests. ITEWC issued notification messages

according to the test timeline through email, SMS and fax communication channels. The

post analysis from the feedbacks received for these COMMs tests indicate that Email is the

most effective and fastest communication medium with low delay times.

5.2. SOP Workshops

As the Warning Centre mainly focuses on observing, analyzing and disseminating warnings

to the national/state disaster management authorities, disaster management authorities need

to build their own SOPs detailing actions to be taken upon receipt of bulletins from the

warning centre as well as instructions to public on what to do and where to go if a tsunami

warning is issued.

ITEWC conducted two SOP workshops on August 19, 2011 and June 05, 2013 at INCOIS,

Hyderabad with participation from the National/State Disaster Management Agencies to

enable them to prepare their own SOP in response to advisories issued by Warning Centre. A

total of 38 and 44 disaster management officials from all coastal states/UTs participated in

these workshops respectively.

5.3. Tabletop Exercise

Tabletop exercises involve creating a simulated emergency situation in a conference room

environment to stimulate the development, training, testing and evaluation of Disaster Plans

and SOPs and to elicit constructive discussion from the participants to assess plans, policies,

and procedures.

As run up to the main exercises (IOWave11 & IOWave14), tabletop exercises were

conducted on August 19, 2011 and June 05, 2013. The goal of the exercise was to familiarize

participants with the stakeholder responsibilities and individual actions and to provide an

opportunity for participants to evaluate their SOPs for tsunami warnings prior to the

functional exercise.


The participants were divided in to groups viz., Tabletop coordinators, National/Central

DMOs, State DMO’s, Ports, Harbors and Navy authorities, Line departments (Police, Fire

etc) and Media. Participants examined the bulletins, conducted group discussions, took

decisions in depth based on their organization’s SOPs with emphasis on slow-paced problem

solving, rather than rapid, real time decision-making.

During the COMMs Tests and IOWave exercises many disaster management agencies

conduct tabletop exercise based on tsunami bulletins received from ITEWC, to test their

SOPs.

6. IOWave14

The ICG/IOTWS during its 9th session held at Jakarta in November, 2012 recommended

that the next Indian Ocean wide tsunami drill (IOWave14) is to be conducted on September

09 & 10, 2014. Three RTSPs (Australia, India and Indonesia) of the Indian Ocean region

will be participating in exercises IOWave14 and will disseminate bulletins to Indian Ocean

rim countries. ITEWC will participate in this drill, both in its capacity as National Tsunami

Warning Centre (NTWC) for India as well as one of the RTSPs for the Indian Ocean region.

6.1. Overview of IOWave14

The exercise will comprise two scenarios on successive days, one in the eastern Indian

Ocean and the other in the North-western Indian Ocean. The first scenario simulates a

magnitude 9.1 earthquake south of Java (10.4S, 112.8E), Indonesia will commence at 0530

hours IST on 09 September 2014. The second scenario simulates a magnitude 9.0 earthquake

in the Makran Trench south of Iran and Pakistan (24.8N, 62.2E) will commence at 1130

hours IST on 10 September 2014. The timeline for issuance of bulletins on 09 and 10

September, 2014 are given in Table 3 & 4 respectively. Participants are requested to follow

the exercise timelines precisely and refer this manual during the tsunami drill.

6.2. Purpose

The purpose of exercise IOWave14 is to evaluate and improve the effectiveness of the

IOTWS, through its operational Regional Tsunami Service Providers, National Tsunami

Warning Centres and National/State Disaster Management Organisations, in responding to a

potentially destructive tsunami. The exercise will provide an opportunity for disaster

management officers to test their operational lines of communications, review their tsunami

warning and emergency response Standard Operating Procedures, and to promote emergency

preparedness. Regular exercises are important for maintaining staff readiness for real events.

This is especially true for tsunamis, which are infrequent but require rapid response when

they occur. The pre-exercise planning and post-exercise evaluation process is as important as

the actual exercise, because it brings together all stakeholders to closely coordinate their

actions. Every disaster management agency is encouraged to participate.

6.3. Objectives of the drill

Validate the Warning Centre dissemination process for issuing Tsunami Bulletins to

national disaster management organizations and other participating agencies.

Evaluate the processes and procedures of agencies receiving and confirming

Tsunami Bulletins.

Evaluate the process of dissemination of bulletins/messages by the DMOs to other

responsible agencies within their area or to the public.


Hone the organizational decision making process about public warnings and

evacuations.

Identify the proper communication methods that would be used to notify and instruct

the public.

Record and assess the elapsed time until the public would be notified and instructed.

6.4. Exercise Scenario Details

Exercise IOWave14 contains, for the first time in Indian Ocean exercises, two earthquake

scenarios on successive days, 9 and 10 September, 2014 with each scenario run in real time

for a period of 12 hours. The scenario details are given below:

Scenario 1 – Java Scenario 2 – Makran Trench

Date: Tuesday, 9 September 2014 Wednesday, 10 September 2014

Time: 0530 IST 1130 IST

Magnitude: 9.1 Mw 9.0 Mw

Depth: 10 km 10 km

Latitude: 10.4 S 24.8 N

Longitude: 112.8 E 62.2 E

Location: South of Java, Indonesia Off Coast of Pakistan

6.5. Level of Participation

The following levels of participation are possible, with each level requiring different levels

of planning and preparation.

Level I: INCOIS National/State/District Disaster Management Authorities

Level II: INCOIS National/State/District Disaster Management Authorities

Local Communities

All disaster management offices are encouraged to participate in either or both events.

However, the administrators of east coast of India and Andaman & Nicobar Islands are

recommended to participate in the tsunami drill on day 1 (i.e, on 9 September, 2014) where

expected tsunami wave heights will be around 0.5-1.3 m from tsunami numerical model

results. The administrators of west coast of India and Lakshdweep Islands are recommended

to participate on day 2 (i.e, on 10 September, 2014) ) where expected tsunami wave heights

will be around 0.5-4.2 m from tsunami numerical model results. Due care should be taken

not to inadvertently alarm the public during the mock drill.

Based on your planning and preparedness, you may decide to (i) limit this drill to check the

communication links between your institution and ITEWC, INCOIS or (ii) activate your

SOPs and take it further down to your institutional/state/district/community level.

Messages: The bulletins to start the exercise will be issued by ITEWC, INCOIS. To avoid

any possible misinterpretation, all bulletins will be in a “dummy” exercise message format

as given in Appendix-II & III. Dummy messages will be issued for each simulated real


message and will continue to be issued until the simulated tsunami has crossed the entire

Indian Ocean region and the exercise concludes.

6.6. Notification Messages and Timelines

Indian Ocean Wave 14 Exercise and For Exercise Purposes Only. In the case of a real

event occurring during the exercise, tsunami warning centre will issue their normal message

products for the event. Such messages will be given full priority and a decision will be made

by control room whether to continue or cease their participation in the exercise

6.10. Resourcing

All participating agencies may elect to stand up a special dedicated shift to allow normal

core business to continue uninterrupted. It is requested that realistic resource levels be

deployed in order to reflect some of the issues that are likely to be faced in a real event.

7. Post Exercise Evaluation

The goal of evaluation is to validate strengths and identify opportunities for improvement

within the participating organizations. Evaluation of this exercise will focus on the adequacy

of plans, policies, procedures, assessment capabilities, communication, resources and inter-

agency/inter-jurisdictional relationships that support effective tsunami warning and decision-

making at all levels of government. Participants that choose to include additional objectives,

for example by exercising public warning and/or response plans, can expand the evaluation

instrument accordingly.

a) how and when notification messages arrived (email, fax, SMS, etc.)

b) whether or not the recipients are able to access the detailed bulletins on the ITEWC

website,

c) whether or not the recipients could understand the messages properly and estimate

the threat level for their coastal region

d) whether or not the recipients disseminated the bulletins/messages to other

responsible agencies or activated the public warning systems, based on their SOP

Sample Exercise Evaluation Forms addressing the respective focus areas and objectives are

included in Appendix-IV. At the end of the test, the recipients are requested to forward their


completed Evaluation forms to Dr. T. Srinivasa Kumar by email ([email protected]) or

by Fax: 040 23895001

8. Conclusion

Tsunami Drills are an effective tool for i) evaluating the readiness of warning centre, ii)

SOPs of the disaster risk reduction agencies, (iii) effectiveness of various logistical and

... POTENTIAL TSUNAMI THREAT FOR INDIAN COAST ...

1. EARTHQUAKE INFORMATION (Revised)



ITEWC INCOIS issuing TEST earthquake with the following TEST parameters:


Depth: 10 km

Date: 09 Sep 2014


Latitude: 10.4 S

Longitude: 112.8 E


2. EVALUATION

Earthquakes of this size sometimes have potential to generate tsunamis. However, so

far

there is no confirmation about the triggering of a tsunami.

An investigation is under way to determine if a tsunami has been triggered. This

ITEWC will monitor sea level gauges and report if any tsunami wave activity has

occurred.

Based on pre-run model scenarios, the zones listed below are POTENTIALLY

UNDER THREAT.

3. TSUNAMI THREAT FOR THE INDIAN COAST

The list below shows the forecast arrival time of the first wave estimated to

exceed 0.02 m amplitude in case of "watch", 0.5 m amplitude in case of

"Alert & Warning" at the beach in each zone, and the amplitude of the maximum

beach wave predicted for the zone. Zones where the estimated wave amplitudes are

less than 0.2m at the beach are not shown.


The list is grouped by State (alphabetic order) and ordered according to the

earliest estimated times of arrival at the beach.

Please be aware that actual wave arrival times may differ from those below, and the

initial wave may not be the largest. A tsunami is a series of waves and the time

between successive waves can be five minutes to one hour.

The threat is deemed to have passed two hours after the forecast time for last

exceedance of the 0.5m threat threshold for a zone. As local conditions can cause a

wide variation in tsunami wave action, CANCELLATION of national warnings and ALL

CLEAR determination must be made by national/state/local authorities.

2. EVALUATION

Data from sea-level gauges confirmed that a tsunami was generated.

The expected period of significant tsunami waves is now over for all threatened

Indian coastal regions, based on ITEWC INCOIS modelling.

Because local conditions can cause a wide variation in tsunami wave action,

CANCELLATION of national warnings and ALL CLEAR determination must be made by

national/state/local authorities. Please be aware that dangerous currents can

continue for several hours after the main tsunami waves have passed.

3. TSUNAMI WAVE OBSERVATIONS

Listed below are maximum wave amplitudes recorded at the specified locations.


Note that wave amplitude is measured relative to normal sea level; it is NOT

INDIAN TSUNAMI EARLY WARNING CENTRE, INCOIS (ITEWC)


----------------------------------------------------------------------------------

... FINAL TSUNAMI BULLETIN FOR THE INDIAN COAST ...






Depth: 10 km

Date: 10 Sep 2014


Latitude: 24.8 N

Longitude: 62.2 E


2. EVALUATION

Data from sea-level gauges confirmed that a tsunami was generated.

The expected period of significant tsunami waves is now over for all threatened

Indian coastal regions, based on ITEWC INCOIS modelling.

Because local conditions can cause a wide variation in tsunami wave action,

CANCELLATION of national warnings and ALL CLEAR determination must be made by

national/state/local authorities. Please be aware that dangerous currents can

continue for several hours after the main tsunami waves have passed.

3. TSUNAMI WAVE OBSERVATIONS

Listed below are maximum wave amplitudes recorded at the specified locations.

Note that wave amplitude is measured relative to normal sea level; it is NOT

the crest-to-trough wave height.
