A (previous) Working Group for the Development of Regional Earthquake Likelihood Models

A scec.gif venture in cooperation with the usgs.gif.

Given a lack of consensus on how to forecast earthquakes, RELM was a working group dedicated to developing a variety of alternative forecast models for California, testing these models against geophysical data, and evaluating their seismic hazard implications.

The results of this working group have been published in a special issue of Seismological Research Letters:

The RELM working group has now evolved and expanded into four other entities (please click links for more info):

  • CSEP (Collaboratory for the Study of Earthquake Predictability) a collaboratory for formal testing of earthquake forecasts and predictions

  • WGCEP (Working Group on California Earthquake Probabilities) a group for combining "best available science" into official forecasts for California

  • OpenSHA (Open Seismic Hazard Assessment) an infrastructure for evaluating the hazard implications of forecasts

  • SCEC's "Earthquake Forecasting and Predictability" focus group (for basic research)
