John Ewert

  Mr. Ewert is a volcanologist with the U.S. Geological Survey (USGS) where he has worked since 1980. He is stationed at the Cascades Volcano Observatory in Vancouver, Washington. His entire career has been spent working on matters pertaining to explosive volcanism, volcano monitoring and volcano hazards mitigation in the United States and around the Pacific Rim.  He has a Bachelor's degree in geology from Beloit College, (Beloit, WI) and completed two years of graduate study at Oregon State University. From 1980 to 1986 he worked at Mount St. Helens on various research projects pertaining to volcanic gas emissions and ground deformation over the course of 15 eruptions, as well as working on projects at other Cascade Range volcanoes. He was one of the founding members in 1986 of the Volcano Disaster Assistance Program (VDAP), a joint US Agency for International Development-USGS program that works with foreign counterparts to monitor volcanoes, forecast eruptions, assess and mitigate hazards and improve understanding of volcanic processes. Since 1986, VDAP has built volcano monitoring infrastructure in 12 countries, responded to 26 major volcano crises, and has saved tens of thousands of lives and hundreds of millions of dollars of property. A highlight of his work with VDAP occurred in 1991 when he was part of the USGS team working at Clark Air Base, Philippines, prior to and during the eruption of Mount Pinatubo, one of the largest eruptions of the 20th century. In addition to responsibilities with VDAP, in 2005 Mr. Ewert developed the methodology to conduct a national volcanic threat assessment for U.S. volcanoes. The results of the assessment are being used to guide long-term improvements to the national volcano-monitoring infrastructure operated by the USGS and affiliated partners, and to improve USGS hazard-information products for the emergency managers, the aviation sector, and the public. Current research interests include a project to develop the World Wide Lightning Location Network for use in early alerting of volcanic eruptions in remote regions of the globe. In November 2010 he assumed duties as the Scientist-in-Charge of the USGS Cascades Volcano Observatory.
