This map from the
U.S. Geological Survey shows the location of the epicenter of an
earthquake that hit Haida Gwaii, B.C. on Saturday, Oct. 27, 2012.
A number of tsunami warnings were downgraded to advisories late Saturday after a 7.7-magnitude earthquake struck off the coast of British Columbia.
A tsunami warning was downgraded to an advisory for a coastal area from the north tip of Vancouver Island to Cape Decision, Alaska, according to a bulletin issued at 11:17 p.m.. PT by the U.S. National Weather Service’s West Coast/Alaska Tsunami Warning Center.
Advisories remained in effect for a region stretching from the Washington-B.C. border to the north tip of Vancouver Island, and for coastal areas of Washington, Oregon and California.
The agency said that “a tsunami has been generated,” which was expected to impact low-lying areas covered by the advisories. The agency advised residents to watch for instructions from local emergency officials.
- “A tsunami advisory means that a tsunami is capable of producing strong currents or waves dangerous to people in or very near the water is expected,” a bulletin issued just before midnight said.
- “Significant widespread inundation is not expected for areas under an advisory.”
- The bulletin said currents that may pose a hazard to swimmers, boats and coastal structures “may continue for several hours after the initial wave arrival.”
