development of the global earthquake consequences database

DEVELOPMENT OF THE GLOBAL EARTHQUAKE CONSEQUENCES DATABASE

@GEMwrld #10NCEE

From the beginning….

… the ambition was that the database will serve to inform users on consequences from past events, as a benchmarking tool for analytical loss models and to support the development of tools to create vulnerability data appropriate to specific countries, structures, or building classes.

Global Earthquake Consequences Database (GEMECD)

• GEMECD is a GIS relational database integrated into the Global Earthquake Model (GEM) OpenQuake web portal.

• For current events, GEMECD will serve as a clearing house of information, posted by users based on the standards and protocols set in the GEMECD documentation.

• In the long term, GEMECD will be a repository of the most relevant and validated data on consequences of the significant events of the last 40 years around the world.

GEMECD Guidelines on Data Collection

• Document gives details on the types of data to be collected for the five categories of consequence data.

• Guidance on assessing data quality, data completeness, data resolution and temporal factors in consequence data (e.g. recovery data).

• Examples of how consequence data can be collected and communicated efficiently are provided.

• This is to ensure a certain degree of uniformity in the data to be included in GEMECD.

Homepage – Filter Function

Quick filter buttons on the map allow one to select events that contain the data you are interested in, in the three main categories in the database:

• Buildings• Casualty • Critical buildings and infrastructure• Secondary hazards (to be added)

Event Overview: 2006 Yogyakarta Earthquake

Event Overview: USGS ShakeMap Overlay

Location details: Data from USGS Shake Maps

One can perform a geospatial query into the underlying USGS Shake Map for the event and show the data at that location.

At the moment this is implemented for point data only. This example from L’Aquila.

Muradiye 1976, Turkey M7.0

… after including MMI data compiled by KOERI.

Event Details

The event details page contains

• Key facts• Narrative summary• Impact summary• Demographics• Human impact• Building damage• Socioeconomic loss• Sources• Epicentre location map

Event Details: study filter

Event Details: CBI study selected

Event Details: CBI Location pop-up

Study Details: CBI asset details

Inventory class: GEM Building Taxonomy

The inventory classification of the consequences database implements the GEM Building Taxonomy 2.0.

Taxonomy string

The taxonomy string is automatically generated from the supplied data attributes.

Inventory class: GEM Building Taxonomy

Users can edit and set the attribute values of the GEM Building Taxonomy using user-friendly menus.

GEM Data and Models on the Platform

GEMECD Data Input

gemecd.org: homepage

Batch data upload: Excel macro template

Locational data input page of the aggregated building damage study due to ground shaking Excel macro template

Building damage page for a specific location in the study (Excel macro template)

Casualty spreadsheet and macro

CBI spreadsheet and macro

It is the ambition of the consortium that once housed in OpenQuake, partners and all users of GEM will be able to help

maintain the quality and quantity of data on earthquake consequences in the database.
