GEM
Mission and Vision
It 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
What is
?
?
OpenQuake is an open source software application that allows
users to compute seismic hazard and risk on any scale.
OPENQUAKE
How to get
?
?
OpenQuake can be downloaded from www.openquake.org where
the latest version is available with the installation documentation.

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
No Image at this time
Curves that give the probability of exceedance a certain loss,
within a time span.
OPENQUAKE
Loss maps
Distribution of the expected losses for a certain probability of
exceedance with a given time span
OPENQUAKE
Where can I find
documentation about what
calculates?
OPENQUAKE
OpenQuake book
All the calculations, equations and assumptions inside of the OpenQuake
engine are described in detail on the OpenQuake book.
OPENQUAKE
What will I calculate with
In the future?
OPENQUAKE
Future releases of OpenQuake will include a
Web 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)
