In the 3rd International Symposium on Earthquake and Disaster Mitigation (ISEDM)

Yogyakarta, 17-18 December 2013

Validation of “Joko Tingkir” in the Real Time Tsunami Warning

System:

A Preliminary Result

Masturyono, Thomas Hardy, Madlazim, and Karyono

Presented by : MASTURYONO

BMKG

BACKGROUND• The InaTEWS has been in operation since

2008 Warning : Potential Tsunami Earthquake Information : No Potential

Tsunami

• Criteria : Magnitude > 7.0 ; Depth < 100 km; Located : in the sea

• Magnitude is not good indicator for Tsunami-genic Earthquake.

• Madlazim developed an aplication to evaluate the earthquake generating Tsunami by analizing the waveform Joko Tingkir

OUTPUT SEISCOMP-3

SEISCOMP-3 is an automatic system to determine the parameters of an earthquake and the tsunami warning.

Input : waveform data stream from the stations

Output : 1. Earthquake parameter (Origin time, Lat, Lon, Depth and the Magnitude)

2. Map showing the location of the earthquake3. Warning (potential or NOT potential generating tsunami)

WARNING OR INFORMATION

IF : NOT POTENTIAL GENERATING TSUNAMI then EARTHQUAKE INFORMATION will be disseminated (Mag, OT, Lat, Lon, Depth, distance from a reference point)

IF : POTENTIAL GENERATING TSUNAMI then 1. TRIGER DSS to produce the warning segment2. Collect and update the sea level monitoring

“JOKO TINGKIR”

Madlazim :A software to calculate parameters as indicator of earthquake generating tsunami.

The Parameters are : Tdur (Rupture duration), Td (Time Dominant), T50EX, and the Products (Tdur*Td, T50EX*Td)

Tdur is associate/equivalent with the length of the rupture zoneTd is associated/equivalent with the width of the rupture zoneT50EX is associate/equivalent with the length of the rupture zone (better estimate than Tdur)The products are associate with the area of the rupture zone Strength Scale of the EQ source

Criteria

THE PARAMETERS

• Td (Dominant Period) is the peak of time

domain (τc)

(τc) = 2π ʃ ʋ2 (t) dt /ʃ ὐ2 (t) dt

• T50EX (T50 Exceeding) is the ratio between the Rms of the amplitude rupture duration for 50-60 seconds and the Rms of those for 0-25 seconds

(Wu and Kanamori, 2005;Lomax and Michelini, 2011)

CALCULATION OF THE PARAMETERS

• T(dur), T(dom) and T50EX are calculated for the first minute of P wave recorded in the station.

• Calculation using a aplication software developed using BASH programing language in the Linux

• Compilation of the seismogram is using SeisGram2K

• Calculation is done in the off line mode

• Using automatic location within 3 minutes or after 30 station recorded the event

• Total time to import the data, reading the waveform, picking the P phase and calculating the parameter is about 1 minute

• The total time needed is about 4 minutes

TEST RESULT FOR SMALLER EARTHQUAKES (ON LINE RUNNING)

Number Event : 171Range magnitude : 5.0 – 7.2Criteria : Td*T50Ex > 10 and Td*Tdur > 650Result :Consistent : 96.5 % ; Parameter below criteria, Observation: No TsunamiInconsistent : 3.5 % : Parameter fulfil the criteria,

Observation : the No Tsunami

SUMMARY• “JOKO TINGKIR” has been implemented in the real

time data flow within the InaTEWS Network for validation purpose

• Preliminary result for showing that 96.5 % of 171 event tested are consistent with the criteria set for the validation test.

• The criteria used in this validation test are Td*T50Ex > 10 and Td*Tdur > 650 for earthquake generating tsunami.

• The total time used to get the result is about 4 minutes, if the Trigger taken from automatic location from InaTEWS
