Thank you Lopez for a standing-room only turnout to Dr.Carlson’s program on Earthquakes and Tsunamis in our region. Some of you have requested a copy of the handout he provided and here it is! Thank you again Dr. Carlson.
Thursday, August 14, 6:00 – 7:00 p.m in the Lopez Library Community Room; The Lopez Island Library and the Friends of the Lopez Library are pleased to present as part of their Summer of Science programming; an evening with marine geophysicist Dr. Richard Carlson. Shocking videos from Sumatra (in 2004) and Japan (in 2011) brought earthquakes & tsunamis into our living rooms. Their science and destructive power have fascinated many including those of us who live along the Pacific’s “Ring of Fire”. In his presentation Only a Matter of Time: Earthquakes & Tsunamis in Cascadia & the Salish Sea, Dr. Carlson will discuss the history of devastating earthquakes & tsunamis as well as the likelihood of them occurring here. Cascadia, a region extending 1100 km from northern California to southern British Columbia, has its very own complete plate system but has no record of historic subduction zone earthquakes, small ones or tsunami-generating monsters. Some research now indicates that once discounted Native American stories of flooding by sea can be validated by evidence of drowned forests, tsunami deposits in coastal marshes and off-shore landslides. In Cascadia, great earthquakes happen on average every 500 years, but not on regular intervals. The question is not “if”, but when and how large the coming tsunami will be. It will surely wreck the coast. It will also reach heights as much as 17 feet in the waters around Lopez Island. Dr. Carlson is currently Regents Professor of Geology and Geophysics at Texas A & M University . He is a marine geophysicist & from 2008 through 2012 he served as Program Director for the Marine Geology & Geophysics Program of the National Science Foundation where a major part of his work was the Cascadia Initiative, a multi-year study of earthquake seismicity in the Pacific Northwest.
