Oklahoma Experiencing Dramatic Increase In Earthquakes

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.

Life In The Cascadia Subduction Zone

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.

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.

Remembering The 'Pioneer Spirit' Of Alaska's 9.2 Earthquake

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.

Research Cruise Makes New Discoveries About Cascadia Megaquake Fault

Cascadia Advective Conductive Heat Expedition. Launching the ROV Jason, the unmanned minisub which deployed heat flow sensors and probes on the seafloor.

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.

Can A Big Earthquake Trigger Another One?

Kesennuma, in the Tohoku region of Japan, was devastated in a March 11, 2011, earthquake and tsunami. A researcher studying recent mega-quakes says this one, centered some 300 miles from Tokyo, could actually mean an increased risk of a quake hitting Japan's capital, one of the most populous metropolitan areas in the world.

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:
