Water levels have risen slightly in Half Moon Bay’s Pillar Point Harbor on Friday morning, but no damage has been reported there or anywhere else in the Bay Area as the region waits for possible tsunami waves to come ashore.

Surges of water as high as 2 or 3 feet were expected to arrive at the region’s coastal areas around 8 a.m., according to the National Weather Service.

Water levels had risen about 8 inches in Pillar Point Harbor, but no significant waves had come in as of 8:15 a.m., assistant harbormaster John Draper said.

The tsunami was triggered by an 8.9-magnitude earthquake that struck the northeast coast of Japan late Thursday night.
