Tsunami fails to materialize locally

The 7.7 magnitude earthquake that sent towering waves crashing into villages in American Samoa failed to produce much of change to San Francisco’s shoreline.

A tsunami warning for the Bay Area was cancelled at 1:42 a.m.

“There might have been some minor sea level changes, but it was no longer a threat,” National Weather Service Meteorologist Rick Canepa said Wednesday.

Changes in wave size locally were “very minor, barely noticeable,” Canepa said. No damage was reported in the Bay Area, he said.

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

Waves rose about 1 foot in San Francisco, and a half-foot at Monterey Bay Harbor, according to the National Weather Service.

San Francisco residents received texts and emails from AlertSF at 5:15 p.m. Tuesday advising them to avoid swimming and boating.

The level of emergency response is determined by data received by the U.S. Geological Survey, including earthquake magnitude and location, Canepa said.
