Bay Area officials eye approaching tsunami


Hundreds of cars have parked on the side of state Highway 92 this morning as people evacuate from coastal San Mateo County cities in advance of possible tsunami waves, but the California Highway Patrol is advising people to park elsewhere so emergency vehicles can get through the area.

Cars began parking along the side of Highway 92 at about 5 a.m. this morning after authorities issued a warning of a possible tsunami sparked

by the 8.9-magnitude earthquake that struck the northeast coast of Japan late Thursday night, CHP Officer Art Montiel said.

Many of the cars were driven by people leaving low-lying coastal communities like Half Moon Bay, Montiel said.

He said the CHP is advising people to not park along the highway because "we need to keep that clear in case we need to bring emergency

vehicles that way."

The National Weather Service estimated waves in the Bay Area would reach heights of 2 to 3 feet, but waves as high as 8 feet are possible at Crescent City in Northern California, officials said.

San Francisco's Department of Emergency Management activated the city's Emergency Management Agency and is accessing risk to coastal areas, department officials said.

The department is advising residents to monitor local media for updates.

The Coast Guard is putting out a broadcast to ensure that mariners are aware of the tsunami warning, a spokesman said.

They are monitoring the situation and will enforce a contingency plan if necessary, OS2 Kyle Jefferson said.

Officials in Santa Cruz, San Mateo, Marin, and Sonoma counties said they are continuing to monitor the situation but have not put into effect any emergency protocols.

The National Oceanic and Atmospheric Administration estimates that the tsunami could hit Point Arena at 7:26 a.m., Point Reyes at 7:39 a.m., Monterey at 7:44 a.m., and San Francisco at 8:08 a.m.

By the time it hits San Francisco the highest water is estimated to reach about two feet, National Weather Service forecaster Steve Anderson


But that is not just one little wave, but rather a surge of water, Anderson said.

Anderson said tsunamis usually occur in a series of surges and the coastal Bay Area could see three to five surges of varying sizes this morning.

Information on the tsunami's size will be changing throughout the morning as the tsunami approaches and more information is gathered.

The tsunami warning was issued for coastal areas of California and Oregon, from Point Concepcion in California to the border of Oregon and Washington, according to the National Weather Service.

The tsunami watch, issued shortly after midnight, was upgraded to a warning at around 12:45 a.m. and is expected to last through the morning, forecaster Will Pi said.

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

Wave ~6 ft in Kahului Maui, and ~3ft in Hilo, Hawaii crested after 3 am.
Probably won't be much higher on the Mainland coastal regions. We have had 19 earthquakes in the East Rift Zone in the last 24,including a 4.5 which shook us less than 2 minutes before the Tsunami warning sirens started wailing.
Kilauea Volcano experienced a new 1.8 mile vent opening (named Kamoamoa) which has apparently 'replaced' Puu O'o vent as that has gone silent.
So lots of activity here on the Big Island. Wishing the best for the folks in Northern Honshu.
