In this task, recent sets of candidate GMPEs will be compiled and reviewed. The GMPEs will be representative of the global (worldwide) data sets for four tectonic categories of earthquakes:
(a) shallow crustal earthquakes in active tectonic regions,
(b) shallow crustal earthquakes in stable continental regions,
(c) subduction zone interface and intraslab (Wadati-Benioff) earthquakes.
(d) volcanic earthquakes
The PEER report 2011-102 (Ground-motion prediction equations 1964-2010) by John Douglas summarizes all published empirical ground-motion prediction equations (and lists those based on simulations etc.) for PGA and elastic response spectral ordinates; it has been produced under the GEM Global GMPEs Project framework.
Selecting and adjusting these global models to region-specific models are addressed in Task 3.
