A New Vision for the USGS

In this second part of an interview with the American Geological Institute, U.S. Geological Survey Director Charles G. Groat speaks candidly about the survey’s budget, culture, science and future.

Partnerships for the Central United States

The central United States doesn't experience the frequency of large earthquakes common for the West coast.  But the country's center has a history of damaging quakes, and researchers are still determining how often the largest quakes could occur.  Given the region's unpredictability, seismologists and geologists from universities and state surveys have created consortia and seismic networks to keep a constant vigil on mid-America.  Here the leaders of one such group describe their mission.
