SALEM, OR -- Tuesday is the 316th Anniversary of the last Cascadia Subduction Zone earthquake and tsunami. Earthquake experts from across the region will take to Twitter, beginning at 10 a.m., to answer questions and help Oregonians prepare for the next "big one."
Ali Ryan Hansen, with the Oregon Department of Geology, says it's an opportunity to learn how bad it could be. "What they know about the science of a Cascadia Subduction Zone earthquake, to find out from emergency management experts what the best ways are to prepare." But, she admits, Oregonians are getting ready, "People know about it and they are being proactive to get ready to face a Cascadia Subduction zone earthquake."
Over the last 3500 years, there have been seven of these massive earthquakes and geologists say we need to be prepared for a 9.0 quake that will hit in the future.
