For most drivers in Washington’s most-populated areas, getting your car’s emissions system tested is an every-other-year ritual. Now, state environment officials are proposing to make changes they say will streamline the process without compromising the region’s air quality.

The same type of tectonic earthquake that hit Japan - involving the collision of plates that make up the Earth's crust - could happen in the Northwest.  Similar faults lie in the Cascadia subduction zone. 

The head of the Pacific Northwest Seismic Network at the University of Washington, John Vidale, told The Seattle Times' Sandi Doughton the Cascadia fault last ruptured in 1700.  Scientists believe it generated at magnitude 9 earthquake and a tsunami that may have been bigger than the one that battered Japan. 

Tidal gauges detected a tsunami wave along the Washington and Oregon coasts Friday morning. But the swell, up to 1.5 feet, went unnoticed by coastal residents who chose not to evacuate.

The first wave of the tsunami to hit the Washington Coast measured 1.6 feet at La Push and about half a foot at Neah Bay and Port Angeles, according to the National Weather Service.

Tsunami Adisory Remains in Effect

Science and Operations officer Kirby Cook says the tsunami advisory is still in effect for the Washington Coast and more waves could be on the way. Cook says more waves are landing in California and that means Washington and Oregon can expect more as well.

If you've had arthroscopic knee surgery for osteoarthritis, maybe you shouldn't have.  And if you've tried any of these treatments, there are questions, too, about whether it was worth it:

The National Weather Service reports the tsunami generated by the 8.9 earthquake that hit Japan on Friday is now coming ashore on the Washington and Oregon coastline.

Meteorologist Johnny Berg says the tsunami advisory is still in effect and waves are coming in, but he says he doesn't have details to offer about how high those waves are.

An AP photographer reports vigorous wave activity on the coast near Moclips, on the central coast, similar to any stormy day on the ocean beaches.

This week Northeast Washington learned one of its residents is suspected of being a Neo-Nazi terrorist. The FBI arrested 36-year-old Kevin Harpham for allegedly planting a bomb in a backpack along the route of Spokane's Martin Luther King Day Parade. Harpham is now being held at the Spokane County Jail.

The National Weather Service (NOAA) has issued a tsunami advisory for the Washington Coast following the massive 8.9 quake in northeast Japan.

Tsunami 'Advisory' Definition, from the National Weather Service:

• Persons in a tsunami “Advisory” coastal area should move out of the water, off the beach and out of harbors and marinas.

• Tsunami Advisories mean that a tsunami capable of producing strong currents or waves dangerous to people in or very near water is imminent or expected.

• Significant widespread inundation is NOT expected for areas in an ‘advisory.'

Waves Expected Here After 7 a.m.; Some Evacuations on Coast

In Pacific and Grays Harbor counties, emergency management officials say "limited" evacuations are taking place. 

In Grays Harbor County, evacuations are taking place in the lowest-lying areas of Taholah, Pacific Beach, Moclips and Iron Springs (north of Copalis Beach), are people are being asked to move to higher ground.  A wave surge of up to 4 feet is projected for those areas shortly after 7 a.m. this morning, the highest level of wave expected to hit Washington state.

Pacific County has implemented its 'reverse 911' system, calling residents on the coast and in lowlying areas and asking them to evacuate calmly. He says an orderly evacuation is happening in Long Beach, Ilwaco and Ocean Park.

People are being asked to stay away from the beaches, harbors and coastal lowlands. Although the initial wave times are indicated, the highest wave may not impact the area for a few hours after that time.

In Oregon, tsunami sirens are blaring in coastal communities, the warning for residents to seek higher ground.  Traffic is heavy on the main transportation artery, Highway 101. In Seaside, at least one hotel has been evacuated. Waves in Oregon may be as high as 6 feet, and expected to arrive between 7 and 8 a.m.

Too much, too little or just right? Depending on who you ask, you will get different answers to the question of whether University of Washington basketball coach Lorenzo Romar went far enough in his punishment of senior guard Venoy Overton.
