The document introduces OpenQuake, an interactive platform for collaborative earthquake risk assessment. OpenQuake includes an engine, tools, and platform. The engine calculates seismic hazard and risk and was released in 2013. The platform and tools are in development and aim to provide web-based access to models, data, and results. The platform will allow users to prepare input, run calculations, and access hazard and risk results and models. It aims to provide an open, modular, documented, and tested system to support risk assessment.

5. • A
mul4-­‐purpose
tool
– Hazard
and
physical
risk
calcula4ons
• Open
and
Transparent
– Take
a
look
at
the
code
on
h^p://github.com/gem
• Modular
– The
engine
is
organised
into
a
number
of
scien4fic
libraries
(OQ-­‐hazardlib,
OQ-­‐
risklib,
OQ-­‐nrmllib)
• Runs
on
clusters
and
laptops
– Op4mised
for
large-­‐scale
calcula4ons
on
Linux
clusters,
but
also
runs
on
a
laptop
• Documented
– We
produce
documenta4on
on
the
methods
behind
the
code
and
how
to
use
the
engine,
and
publish
in
peer-­‐review
journal
publica4ons
• Tested
– Tes4ng
is
an
integral
part
of
the
development
process
