Weather service forecaster Mark Strobin said the advisory was canceled at around 1:35 a.m. after authorities determined that conditions lending to a destructive tsunami force no longer exist or threaten to materialize locally.

A slight tsunami surge was measurable along the California coast as a result of the Samoan earthquake, Strobin said, and lingering fluctuations in sea level will likely persist.

"The tsunami will continue to cause non-damaging sea level fluctuations after the event," Strobin said.

The tsunami amplitude - the measurable surge above normal sea level - measured a half-foot at Monterey Bay Harbor, slightly more than one foot at Arena Cove in Mendocino County, and about one foot in San Francisco.

Aftershocks near the Samoa islands this morning, some of which have been preliminarily measured at 5.0-magnitude, are not strong enough to generate destructive tsunamis, Strobin said.

There were no local reports of damage from Tuesday's tsunami surge, and no resulting emergencies, according to the U.S. Coast Guard Sector San Francisco.

The California Emergency Management Agency announced Tuesday it had coordinated with local, state and federal officials to ensure residents were kept safe.

The last tsunami to cause damage to the Bay Area was in Santa Cruz County in 2006.
