Emergency managers in Oregon have a new tool to educate the public about earthquake preparedness. It's a comic book. And it's co-produced by one of the nation's top comic book publishers.

Research geologists have just finished a field trial to test a less invasive way to complete seismic hazard surveys.

So far this year, Oklahoma has had more earthquakes of a magnitude 3.0 or greater than any other state in the country — including California. More than 200, just since January.

This is a new and remarkable phenomenon. Just five years ago, Oklahoma was averaging only two 3.0 earthquakes a year. Now, it’s averaging one or two a day.

Scientists are saying that oil and gas-related activity, including fracking and wastewater disposal wells in the state, may be partially to blame.

Ross Reynolds speaks with Bonnie Henderson about her new book "The Next Tsunami: Living on a Restless Coast."

Just off the coast of Washington and Oregon is a fault line with potential to unleash an earthquake larger than the deadly magnitude 9 Japan quake in 2011 that triggered a tsunami.

Henderson tells the story about how geologists learned of the Cascadia Subduction Zone and how public officials have tried to adopt safety measures.

Spoiler alert: when you hear a siren, walk and keep walking.

Why Some Buildings Aren't Ready For 'The Big One'

When disaster strikes, architects and engineers see their best laid plans put to the test.

When the Nisqually Earthquake struck in 2001, home repair expert Roger Faris was at the Phinney Neighborhood Center celebrating the retrofit of the former school lunchroom.

Steve Scher recently met with Faris and engineer Dan Say to point out the work that was done to reinforce the old school building. They say there are still hundreds of un-reinforced masonry buildings at risk if and when the next earthquake hits.

Moments before the magnitude-7.2 earthquake struck central and southern Mexico, people received a text message warning on their phones.

Ross Reynolds talks with John Vidale, Washington state seismologist and UW professor, about the challenges to predicting earthquakes.

The extent of the damage isn't yet clear and the six deaths reported so far may be followed by news of other fatalities.

But on the morning after a massive, 8.2 magnitude earthquake off the coast of northern Chile there are sighs of relief there and in neighboring Peru.

Fifty years ago, a large earthquake centered near Anchorage, Alaska, set off a fatal chain of destruction that reached through Washington and all the way down into California.

March 27, 1964 – Good Friday – was a typical early spring day in Seattle. But just after 7:30 p.m., an earthquake disrupted the peaceful evening all along the Pacific coast.

Marcie Sillman talks with Seattle Times science reporter Sandi Doughton about Japan's efforts to rebuild after the devastating earthquake and tsunami on March 11, 2011.

Name the volcano that geologists consider the most dangerous in the Northwest.

It's been a busy summer on the high seas for researchers trying to figure out the inner workings of an ominous earthquake fault. The Cascadia Subduction Zone runs offshore from Vancouver Island to Northern California. When it rips, we could have a magnitude 9 catastrophe.

University of Washington geophysicist Paul Johnson led a nearly month-long research cruise to the likely epicenter for the Big One. His ship carried an unmanned minisub to probe the seafloor directly over the still somewhat mysterious Cascadia earthquake fault.

There's a joke among scientists: Prediction is difficult, especially about the future. For Ross Stein, it wasn't a joke after the Indian Ocean quake and tsunami in 2004. It killed some 275,000 people. "I just felt almost a sense of shame," Stein says, "that this tragedy could have been so immense in a world where we have so much intense research effort."

How To Survive An Earthquake

An estimated 1,000 earthquakes occur in Washington state each year. Fortunately, most are of them are small, and only about 15 to 20 are felt by residents. If you're not sure what to do when an earthquake strikes, the Regional Public Information Network has some valuable guidelines:
