Tsunami advisory for coastal B.C.


Times ColonistFebruary 27, 2010 9:02 AM

The West Coast Alaska Warning Centre upgraded British Columbia to a tsunami advisory level this morning at 7 a.m. following a large earthquake magnitude 8.8 that occurred off the coast of Chile.

The advisory includes all of coastal B.C.

The advisory means there is a possibility of strong localized currents. Provincial officials said no significant wave was expected but low-lying coastal areas and beaches are at risk. Experts predict a first wave arrival time of 3:11 p.m. at the southern B.C. coastline.

Persons in tsunami advisory areas should move out of the water, off the beach and out of harbours and marinas.

The provincial emergency program will issue updated information as it becomes available.

A tsunami warning was also issued by the Pacific Tsunami Warning Center, notifying dozens of countries and remote island nations from Hawaii to Japan of possible "widespread damage" from waves, generated by the massive quake which may reach three metres (nine feet). That warning does not apply to British Columbia, Alaska, Washington, Oregon and California, which all received the tsunami advisory.
