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.

As search efforts intensify around the site of Washington state’s devastating mudslide, geologists are looking into causes of the rapid collapse of the 1,500-foot-wide segment of hillside in Snohomish County that suddenly cut away and crushed the homes and roads below.

The chief culprit appears to have been the glacial composition of the hillside, which is made of silt, clay and soil, and very little rock, which tends to be very loose.

David Hyde visits the basement of Burke Museum to speak with geology writer David Williams about the historical artifacts that have been unearthed by Seattle's relentless earth moving.

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.

The world is a mysterious place. In labs and observatories around the world, people are trying to make sense of nature’s secrets. This hour on The Conversation we talk to scientists and science writers about the natural world around us and what scientists are doing to harness its power.

There are many stories of great floods out there, first and foremost the fable of Noah's ark. But some geologists have found that many of these legends have some basis in historical fact. We talk with University of Washington professor and MacArthur award-winner Dave Montgomery, the author of "The Rocks Don't Lie: A Geologist Investigates Noah's Flood."
