Broadband Discrimination Studies

Abstract

The broadband recording capabilities of the Seismographic Station of the University of California have been expanded to three stations, Berkeley (BKS), Jamestown (JAS), and Whiskeytown Dam (WDC). These stations provide ground motion data at two gain levels in the spectral range of 10 Hz to 100 sec. A library of broadband data is accumulating which is very useful in a wide variety of investigations. A body-wave surface wave discriminant at regional distances separates nuclear explosions from natural earthquakes, explosion collapses, and explosion aftershocks down to magnitude 3.5 in the western United States. The reason why this discriminant works is still not completely understood.
