HONOLULU (AP) -- The latest on tsunami advisories that were issued for Hawaii and parts of California after a powerful earthquake off Chile (all times local):

9:50 a.m.

The National Tsunami Warning Center has canceled a tsunami advisory for a 300-mile stretch of California's coast.

The advisory had applied to the coast from San Onofre State Beach, 45 miles southeast of Los Angeles, up to Ragged Point, 50 miles northwest of San Luis Obispo.

The warning center said Thursday that the tsunami generated after an magnitude-8.3 earthquake in the Pacific Ocean off Chile no longer poses a threat.

The center says, however, that some areas may see small sea level changes and surges.

The tsunami was recorded from San Diego to Alaska but only reached the center's advisory level for part of California.

9:30 a.m.

A small tsunami triggered by a deadly earthquake off Chile has reached as far north as Alaska.

The National Tsunami Warning Center says King Cove, Alaska, reported water heights of six-tenths of a foot late Thursday morning.

Tsunami effects also were felt along the coasts of California, Oregon and British Columbia.

Most of the surge occurred outside a 300-mile stretch of California under a tsunami advisory, said Paul Whitmore, the center's director in Palmer, Alaska.

Whitmore says the advisory likely will be lifted in the early afternoon.

A tsunami advisory has been dropped for Hawaii after a powerful earthquake off Chile, but it remains in effect for parts of coastal California.

The Pacific Tsunami Warning Center dropped the Hawaii advisory Thursday morning.

Officials originally issued a more serious tsunami watch for the state shortly after Wednesday's magnitude-8.3 earthquake. But they later downgraded it to an advisory, saying no major tsunami was expected.

The National Weather Service says a 3-foot wave was recorded at Hilo Harbor on Hawaii's Big Island shortly after 4 a.m. Thursday. Forecaster Tom Birchard says he hasn't heard of any significant impacts.

The National Tsunami Warning Center says an advisory remains in effect for Ragged Point, California and San Onofre State Beach, California.

Authorities in California are calling on people to refrain from waterfront activities.
