SEMINAR - Ross Stein
Biography
My research focuses upon how earthquakes interact through the transfer of stress. Examples of such interaction include the progression of mainshocks along a fault, aftershocks, seismic quiesence, and earthquake clustering. My collaborators and I are interested in how one earthquake can promote subsequent shocks at some sites and inhibit them in others.
This work is driven by an attempt to deepen our understanding of the physics of earthquakes, and a desire to develop a new way to make probabilistic hazard assessments. Our tools are seismology, geophysics, elasticity theory, structural geology, and geomorphology.
In addition, I study the deformation of the earth's surface associated with earthquakes, fault creep, and volcanic processes. This work seeks to infer rupture and fault geometry, and to understand the relationship between earthquake deformation and geologic structures. Our tools are classical and space geodesy. Key interests are blind thrust faults, high-angle normal faults, and magmatic inflation and collapse.
My work is currently funded by a Cooperative R&D Agreement with Swiss Re, the world's second largest insurance company; and through a series of research grants from NASA. My first R&D project with Swiss Re was a study of the earthquake threat to Istanbul in the wake of the 1999 Izmit shock; the current Swiss Re project assesses the earthquake hazard for Tokyo, and with participation by several leading Japanese scientists. A 1996-2001 R&D project earthquake hazards in the San Francisco Bay area was carried out with PG&E. Other recent studies were funded by U.S. Office of Foreign Disaster Assistance and FEMA.
Over the past several years, I have participated in documentary films, including 'Killer Quake' (NOVA, 1995), 'Great Quakes: Turkey' (Discovery Channel, 2001), 'Earthquake Storms' (BBC, 2003), and an IMAX film, 'Forces of Nature' (National Geographic), which wass released in summer 2004.

Earthquake and Volcano Deformation and Stress Triggering Research Group
They measure the deformation of the earth's surface to understand earthquakes and volcanic processes, and they study how one earthquake or volcanic event contributes to the next by the transfer of stress.

This webpage details the model made by Ross Stein and demonstrated most recently at the May 2000 USGS Open House by the Earthquake Hazards Team. The website has been constructed due to the great public interest shown at the Open House, particularly by teachers.
This website includes a TV documentary film clip, animation and photographs of the model 'in action', a lengthy model description, and associated diagrams. It also includes technical specifications (bottom of this page) to aid those wishing to build their own model.

Predicting Quakes - Earthquakes can cause death and destruction in a matter of seconds with little more than a minute's notice. Betty Anne Bowser explores some cutting-edge technology in seismology.
Here is a 11-minute segment that appeared on the NPR broadcast on Wednesday, June 2, focusing on earthquake prediction.
