U.S. West Coast, Alaska, and British Columbia coastal regions

Tsunami Warning Center
Tsunami Advisory Cancellation
#35 issued 03/12/2011 at 8:10AM PST
The Tsunami Advisory is canceled for the coastal areas from Alamitos Bay, California (20 miles SE of L.A.) to the Oregon-California border.
Damaging tsunamis are no longer expected to impact the U.S. west
coast states, Alaska, and British Columbia. As
local conditions can cause a wide variation in tsunami impact,
the all clear determinations must be made by local authorities.
Tsunami amplitudes have dropped below dangerous levels at most
locations along the U.S. west coast, Alaska and Canada. Sea
level conditions still vary greatly from location to location
along the coast. Decisions relating to reoccupation of coastal
zones must be made by local authorities.

Amp. - Tsunami amplitudes are measured relative to normal sea
level. It is NOT crest-to-trough wave height.
Values are given in both meters (M) and feet (FT).
NO NEW UPDATE.
At 9:46 PM Pacific Standard Time on March 10, an
preliminary magnitude 8.9
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 last West Coast/Alaska Tsunami Warning Center message
issued for this event.
To repeat, NO tsunami warning, watch or advisory is in effect for
the U.S. West coast states, Alaska, and British Columbia.
