 Map showing earthquakes

VANCOUVER, WA
A 6.4 earthquake has hit right off the Vancouver Island within the past hour. The strong earthquake did NOT prompt a tsunami  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. Some of these areas may experience non-damaging sea level changes. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.

At 12:42 PM Pacific Daylight Time on September 9, an earthquake with preliminary magnitude 6.7 occurred 50 miles/80 Km south of Port Alice, British Columbia . (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 atsunami travel time map and table.c
