The following organization provides Earthquake Education and Preparedness information.
The Southern California Earthquake Center (SCEC) is a community of scientists and specialists
who actively coordinate research
on earthquake hazards at nine core Institutions,
and communicate earthquake
information to the public. SCEC is a National Science Foundation
(NSF) Science and Technology
Center and is co-funded by the United States Geological Survey
USGS.
The Southern California Earthquake Center's
mission is to promote earthquake hazard reduction by:
- Defining when and where future damaging earthquakes will
occur in Southern California
- Calculating the expected ground motions
- Communicating this information to the public
The Center's goal is to develop
a "Master Model" of seismic hazard in Southern California by integrating various
earth science data through probabilistic seismic hazard analysis.
A database of publised papers based on SCEC funded research is available, as well as several
data sets, briefly summarized below:
- SCEC Data Center: Seismic data sets, recent
earthquake lists and maps, basic earthquake science facts,
"SeismoCam" (live and recorded seismograms) and links
to other data centers.
- Strong Motion Database:
A relational database providing information about and access
to strong ground motion recordings. The database currently contains
over 5,000 accelerograms from 119 California earthquakes. The
amount of data in the database is still growing and the database
is fully Web-accessible.
- Empirical Green's Functions Library:
A relational database and data repository containing 84,641
seismograms from 1500 southern California earthquakes. The purpose
of this site is to provide fast and easy access to recordings
of small earthquakes that might be used as Green's functions
for predicting the ground motion from larger earthquakes.
- Southern California Integerated GPS Network (SCIGN):
An array of Global Positioning System (GPS) stations
distributed throughout southern California with emphasis on the
greater Los Angeles metropolitan region.
- Campaign-Mode GPS Data at the SCEC Data Center:
The SCEC Data Center archive of GPS data contains data from "survey-mode"
precise GPS measurements made in Southern California by various
universities, Federal organizations (notably the US Geological
Survey and the National Geodetic Survey), the California Department
of Transportation, and Southern California counties, cities,
and water districts.
- Crustal Deformation Velocity Map: The velocity map represents the first attempt
by the Crustal
Deformation Working Group of the Southern California Earthquake
Center to produce a unified horizontal velocity field showing
contemporary interseismic deformation in southern California.
- ROSRINE Project: Resolution of Site Response Issues from the Northridge Earthquake:
A variety of site response data from L.A. area sites are available,
such as P and S-wave velocities using the suspension logging
method.
