Earthquake
Hazards Program: USGS Project Proposals
Current research activities supported by the USGS Earthquake
Hazards Program.
Earthquake
Hazards Program: External
Research Program
The USGS supports research projects outside the USGS
that will assist in achieving the goals of the National
Earthquake Hazards Reduction Program (NERHP)
Seismologic Studies
Earthquake locations and other characteristics, even of very small earthquakes,
provide primary constraints on where faults are and how active they might
be. Recordings of the waves they emit enable seismologists to measure
these characteristics, as well as provide information about how the ground
shakes when earthquakes occur. Earthquake, or seismic, waves also
provide information about the structure of the Earth, and may be generated
either by earthquakes or by other sources such as explosions. Permanent
seismic monitoring networks provide
much of the data for all these types of studies.
Crustal Deformation Studies
Forces inside the Earth cause it to distort and deform, which ultimately
causes earthquakes in the uppermost brittle part of the crust. The
Global Positioning System (GPS) is now being used to measure this deformation.
A continuously
recording GPS monitoring network operates in the New Madrid region, and
periodic GPS measurements are made throughout the CEUS.
Friends
of the Central US
This small working
group, led by the USGS and Illinois State Geological Survey, stimulates collaboration and study of earthquake problems
in the Illinois basin.
