Tsunami

My thoughts and prayers for all those affected by this devastating event in Japan.

Tsunami warning has been issued for the central and northern California coast and Oregon, the National Weather Service announced early Friday.

In the San Francisco Bay Area, an emergency warning system announcement for a tsunami warning was braodcast just after 1 a.m. Waves could begin arriving in Crescent City, Calif., at 7:23 a.m. and the Bay Area shortly after 8 a.m.

A lower-level tsunami advisory was issued for the Southern California coast south of Point Concepcion, which includes southern San Luis Obispo County and the counties of Ventura, Los Angeles, Orange and San Diego.

The purpose of this brochure is to increase awareness and knowledge of tsunamis. Please share what you learn; knowing the right information may save your life and the lives of those you love.

The phenomenon we call “tsunami” (soo-NAH-mee) is a series of traveling ocean waves of extremely long length generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. Underwater volcanic eruptions and landslides can also generate tsunamis. In the deep ocean, their length from wave crest to wave crest may be a hundred miles or more but with a wave height of only a few feet or less. They cannot be felt aboard ships nor can they be seen from the air in the open ocean. In deep water, the waves may reach speeds exceeding 500 miles per hour.

Tsunamis are a threat to life and property to anyone living near the ocean. For example, in 1992 and 1993 over 2,000 people were killed by tsunamis occurring in Nicaragua, Indonesia and Japan. Property damage was nearly one billion dollars. The 1960 Chile Earthquake generated a Pacific-wide tsunami that caused widespread death and destruction in Chile, Hawaii, Japan and other areas in the Pacific. Large tsunamis have been known to rise over 100 feet, while tsunamis 10 to 20 feet high can be very destructive and cause many deaths and injuries.

The Tsunami Warning System (TWS) in the Pacific, comprised of 26 participating international Member States, monitors seismological and tidal stations throughout the Pacific Basin. The System evaluates potentially tsunamigenic earthquakes and disseminates tsunami warning information. The Pacific Tsunami Warning Center (PTWC) is the operational center of the Pacific TWS. Located in Honolulu, Hawaii, PTWC provides tsunami warning information to national authorities in the Pacific Basin.

  1. Maybe you may want to add a twitter button to your site. I just marked down the blog, but I had to complete this by hand. Simply my 2 cents.
