To: U.S. West Coast, Alaska, and British Columbia coastal regions From: NOAA/NWS/West Coast and Alaska Tsunami Warning Center Subject: Tsunami Information Statement #1 issued 04/7/2011 at 7:40AM PDT A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas. Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides. At 7:32 AM Pacific Daylight Time on April 7, an earthquake with preliminary magnitude 7.4 occurred near the east coast of Honshu, Japan . (Refer to the United States Geological Survey for official earthquake parameters.) Pacific coastal regions outside California, Oregon, Washington, British Columbia, and Alaska should refer to the Pacific Tsunami Warning Center messages for information on the event. This will be the only statement issued for this event by the West Coast/Alaska Tsunami Warning Center unless conditions warrant. See the WCATWC web site for basic tsunami information, safety rules, and a tsunami travel time map and table. (NOTE: Travel time maps and tables indicate forecasted times only, not that a wave was generated.)
