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.

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.

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)
