Tsunami alert issued after powerful Alaska earthquake: US officials

A tsunami warning was issued Friday for coastal areas of Alaska's southern Kenai Peninsula after a powerful 7.0-magnitude earthquake struck, the National Oceanic and Atmospheric Administration said.

"For other US and Canadian Pacific coasts in North America, the level of tsunami danger is being evaluated," the agency's US Tsunami Warning System bulletin said.

The Pacific Tsunami Warning Center said no destructive Pacific-wide tsunami was expected, and there was no threat to Hawaii.
