This Tsunami Advisory is for residents along the California, Oregon, Washington, British Columbia, and Alaska coast.

NO tsunami watch or warning is in effect for the states and provinces listed above. It is unlikely that these regions will upgraded to a tsunami warning or watch. Please refer to the PTWC message for further information about the warning.Based on the earthquake location, magnitude 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 7:41 AM Pacific Standard Time on November 14, an earthquake with preliminary magnitude 7.7 occurred in northern Chile. (Refer to the United States Geological Survey for official earthquake parameters.)
Messages will continue to be issued hourly by the WCATWC until the Pacific Tsunami Warning Center issues a cancellation or final message.

(NOTE: Travel time maps and tables indicate forecasted times only, not that a wave dangerous to the U.S. west coast, British Columbia, or Alaska was generated.)
