OPENQUAKE

Mission and VisionIt is GEM’s mission to engage a global community in the design, development and deployment of state-of-the-art models and tools for earthquake risk assessment worldwide.OECD’s Global Science Forum created the opportunity for an initiative to leverage (scientific) knowledge on earthquake risk for the benefit of society, worldwide. What GEM envisions and has started to work on, is the bringing together of state-of-the-art science and national, regional, international organisations as well as individuals, in a global collaborative effort that will have a lasting impact on seismic risk assessment.

?OPENQUAKE

OpenQuake is an open source software application that allows

users to compute seismic hazard and risk on any scale.

What is ?

?OPENQUAKE

OpenQuake can be downloaded from www.openquake.org where

the latest version is available with the installation documentation.

How to get ?

?OPENQUAKE

The OpenQuake team coodinates through many communication

channels such as IRC, mailing lists, blogs, forum, etc…

What can I calculate with

today ?

OPENQUAKE

Currently OpenQuake is alpha-code meaning that it is a development release and all interaction

with the tool is through a terminal interface

OPENQUAKE

Hazard Curves

Curves that give the probability of exceedance of a certain intensity measure

level, within a time span.

OPENQUAKE

Hazard Maps

Distribution of the expected ground motion for a certain probability of

exceedance with a given time span

OPENQUAKE

Loss curves

Curves that give the probability of exceedance a certain loss,

within a time span.

Where can I find

documentation about what

calculates?

OPENQUAKE

All the calculations, equations and assumptions inside of the OpenQuake

engine are described in detail on the OpenQuake book.

What will I calculate with

In the future?

OPENQUAKE

Future releases of OpenQuake will include aWeb based user interface

OPENQUAKE

Seismic Hazard disaggregation

The disaggregation provides the contributions to the hazard of discrete

combinations of basic parameters considered in the calculations (e.g.

magnitude, rupture-site distance)

OPENQUAKE

Ground motion fields for single events

Distribution of the ground motion in a region for a single earthquake

OPENQUAKE

Disaggregation of losses

The disaggregation provides the contributions to the losses of discrete

combinations of basic parameters considered in the calculations (e.g.

magnitude, rupture-site distance)
