Subject: Tsunami Information Statement issued 01/9/2010 at 4:32PM PST
At 4:28 PM Pacific Standard Time on January 9, an earthquake with preliminary magnitude 6.4 occurred 15 miles/24 Km southwest of Eureka, California.
The magnitude is such that a tsunami IS NOT EXPECTED. However, in coastal areas of intense shaking, locally generated tsunamis can be triggered by underwater landslides. This will be the only WCATWC message issued for this event.
The location and magnitude are based on preliminary information. Further information will be issued by the United States Geological Survey or the appropriate regional seismic network.
