Speaker: Bill Chadwick, CIMRS, Oregon State University
Topic: When will Axial Seamount erupt next?
Axial Seamount is the most active volcano in the Pacific Northwest, with 3 eruptions in the last 22 years - it just happens to be almost a mile underwater, so is usually hidden from view. It is located about 260 miles west of Astoria on the Juan de Fuca Ridge, a tectonic plate boundary and spreading center. This talk will tell stories from our recent expedition to Axial Seamount in September 2020 - made unusual by the COVID-19 pandemic and the Oregon wildfires - and will present results from the cruise and our efforts to forecast the next eruption using the continuous monitoring data from the Ocean Observatories Initiative's Cabled Array. Axial Seamount has now re-inflated by > 80% since its last eruption in April 2015, but the rate of inflation has recently slowed so its next eruption is still probably several years away.
