Virginia Tech Seismological Observatory: VTSO maintains a seismic network in the Giles County vicinity. This page contains a short discussion about earthquakes in Virginia and pointers to earthquake catalogs and other information compiled by the Observatory.
SeismoSurfing: This page provides effectively "one-stop shopping" for links to just about anything involved with earthquake seismology. Included are links to Global and regional (on several scales) earthquake catalogs, seismicity maps, and organizations involved with seismology. The is also a set of links to sites related to volcanoes.
U.S. Geological Survey Earthquake Hazards Program has interactive maps with links for latest earthquakes (world for magnitude at least 4 and U.S. with magnitude at least 1). The USGS National Earthquake Information Center (NEIC) top page presents the same information but in a different format, and it has links for those who want to get data (waveforms and focal mechanisms). Here is an article on the USGS earthquake bulletins and catalogs.
The Incorporated Research Institutions for Seismology (IRIS). IRIS is a consortium of
universities and other institutions which supports earth science
research in the U.S. and around the world. See their special events
page, with links to pages with information about recent major
earthquakes. One program within IRIS is the Global
Seismographic Network (GSN). Clicking on the world map brings up
an interactive map showing over 128 stations (as of 2003).
Also on this site is an interactive
map showing recent large earthquakes. Another program within IRIS is
Education and Outreach. Among their offerings is a set of
seismicity maps showing events on different recent time scales. One can
also build one's own map. They also have a set of PDF "one pagers"
which are mini-tutorials on various aspects of earthquake seismology. The Data Management System (DMS) of IRIS is the repository of seismic data from most of the seismic networks in the world, as well as for short-term seismic experiments and the USArray.
The USArray component of the EarthScope experiment is a continental-scale seismic observatory designed to provide a foundation for integrated studies of continental lithosphere and deep Earth structure over a wide range of scales. USArray will provide new insight and new data to address fundamental questions in earthquake physics, volcanic processes, core-mantle interactions, active deformation and tectonics, continental structure and evolution, geodynamics, and crustal fluids (magmatic, hydrothermal, and meteoric).
Earthquake Country. The
Southern California Earthquake Center (SCEC) and the United States
Geological Survey (USGS) have created a series of web pages aimed at educatiing the public about earthquakes. One, on the 2004 NBC television miniseries 10.5, separates fact from movie fiction.
Event Catalogs: Three sources for finding sets of events sorted by
location, time, magnitude, and database: the
USGS, the Harvard CMT Search, and the IRIS DMC event database.
Where is
that earthquake? Tells you distance and phase information for
all events from various "finger" catalogs to a chosen station. Also has a
link to a set of traveltime tables.
Virtual Earthquake: This Web site leads one through an interactive program designed to show how a seismologist would locate an earthquake and find its Richter magnitude.
Steve Newman's Earthweek: A Diary of the Planet is published weekly in
many papers: Weekly summary highlighted map | Daily updates. Included in the weekly summary page are brief reports about that week's seismic and volcanic activity — plus reports on climate topics and other things that he finds interesting. Link to archives.
