The U.S. Geological Survey published its first updated earthquake maps in six years Thursday. The new maps show higher risks in the Pacific Northwest. The new maps are a synthesis of new research and up-to-date modeling techniques, applied to seismic hazards across the country.

An estimated 1.2 million people in the Northwest took part in an international earthquake drill Thursday.

A storied research sub that explored and filmed the wreck of the Titanic is making an appearance in the Northwest. The deep-diving submarine "Alvin" is in Astoria Monday,  August 26 through Friday, August 30 while its support ship changes crews. It's actually one of two well-known submersibles passing through the port town.

An earthquake measuring 3-point-6 was felt on the Key Peninsula this morning. The University of Washington Seismology Lab says the quake happened around 11:40 and was centered some 15 miles west of Tacoma.

This week a research ship is retrieving dozens of seismometers that have spent the last year on the ocean floor off the Northwest coast. Earthquake scientists hope the data they're about to get will shed more light on the structure of the offshore Cascadia fault zone. That plate boundary will be the source of the Big One whenever it rips.

The earthquake and tsunami threat to the Northwest from the offshore Cascadia fault was in the news in multiple ways Thursday. Canadian researchers have reconstructed a prehistoric record of great earthquakes on that shared fault. It reconfirms that we're due for another Big One. Coincidentally in Oregon, tsunami preparedness is getting a renewed look.

The Blue whale is believed to be the largest animal ever to exist. But nobody remembers number two. Fin whales are the second largest animals on the planet, weighing in at around 80 tons. And they’re very mysterious creatures. Now scientists have gained better access to the giant whale’s secret lives – almost accidentally.

As Superstorm Sandy barreled down on the East Coast Sunday, there was a massive earthquake off the coast of British Columbia. It didn’t get much attention. But both events were reminders to prepare for the long-term impacts of natural disasters. That’s the message coming out of a regional conference in Portland this week.

Researchers have found fresh evidence of 26-foot-high tsunami waves that washed more than three miles in to the Olympic Peninsula.

Thursday, Oregon, Washington, and Idaho joined their Western neighbors for an earthquake drill of unprecedented scale. Some of the record participation was due to businesses joining in the drill. In our area, among those practicing were architects, utilities and banks.
