- Calif. Quake Prompts Brief Tsunami Warning
Yahoo News, June 14, 2005- A powerful earthquake roiled the waters off the northern California coast, triggering a brief tsunami warning and the evacuation of thousands of residents from a community with a history of battling killer waves. The 7.0-magnitude quake struck at about 7:50 p.m. Tuesday about 90 miles southwest of the coastal community of Crescent City and 300 miles northwest of San Francisco, according to the U.S. Geological Survey. A tsunami warning was briefly in effect from the California-Mexico border north to Vancouver Island, British Columbia, but was called off about an hour after the quake hit. There were no reports of significant damages or injuries. The area hit is where the North American, Pacific Ocean and Juan de Fuca plates converge and has earthquakes of this magnitude about once a decade, said Lucy Jones, the scientist in charge of the U.S. Geological Survey office in Pasadena.
USGS lists as a 7.0 but the initial magnitude, during a tsunami warning, had it listed as 7.4.
