Abstract

The article discusses the event of North Korea's nuclear test done on 9 October 2006. According to US Geological Survey the event measured at magnitude of 4.2 and seismographs around the world registered shock waves due to underground nuclear test. The survey says it was not large enough to be caused by conventional explosives nor it can be termed completely successful nuclear test. Responses and comments of nuclear scientists and various organizations on the event are presented.

Author

Leslie, Mitch

Subjects
*GEOLOGIC faults, *EARTHQUAKE zones, *GEOLOGICAL surveys, *SEISMOMETERS
Abstract

The article reports that every day, several of California's more than 1000 shifting faults shake some part of the state. This clearinghouse of earthquake data keeps check on the ones that rattle northern California. Sponsored by the University of California, Berkeley, and the U.S. Geological Survey, the site catalogs magnitude, depth, location, and other measurements for earthquakes dating back to 1967. One should check out near-real-time recordings from a network of seismographs scattered around northern and central California.
