NEW "RELM" Web Site

The SCEC/USGS working group for the development of Regional Earthquake Likelihood Models (RELM) announces an all new web site (http://www.relm.org), where you can find all pertinent information related to the effort.

RELM is the lead activity of the Southern California Earthquake Center (SCEC) in the area of seismic hazard analysis.

Using southern California as a natural laboratory, the goals of RELM are to:

  1. develop a variety of viable, geophysically based earthquake-forecast models for the region (a specification of where and how often all damaging earthquakes are likely to occur).
  2. test these models for consistency with existing geophysical data (e.g., historical seismicity) and design and document conclusive tests with respect to future observations (establish stationary targets)
  3. examine and compare the implications of each model with respect to probabilistic seismic hazard analysis (PSHA).

This will:

  1. help define existing uncertainties in seismic hazard analysis.
  2. identify the research topics needed to reduce these uncertainties.
  3. identify which models are exportable to other regions where the options are fewer.

You can also join various RELM email groups (by clicking the "Participants & Email Groups" button) to stay abreast of, or participate in, various elements of this rapidly evolving project.
