David W. Ramsey
Dave Ramsey is a Geologist with the U.S. Geological Survey (USGS) at the Cascades Volcano Observatory in Vancouver, Washington. He specializes in volcano hazards assessment and risk research and applications as a member of the Volcano Disaster Assistance Program (VDAP), co-funded by the USGS and the U.S. Agency for International Development's Bureau of Humanitarian Assistance (USAID/BHA).
Dave is a co-leader of the USGS Risk Community of Practice, which focuses on risk research and applications from across the USGS to directly support decision makers in their efforts to better understand societal risk from hazards and to have the necessary information to make science-based, risk reduction decisions. He also serves as a Geohazards Advisor for BHA's Natural Hazards Disaster Risk Reduction team, providing technical assistance to USAID on geological hazards and risk. Dave is involved with monitoring and evaluation of VDAP activities and planning of future initiatives to assist foreign counterparts with preparing for and responding to volcanic crises. He is also working on compilation and analysis of a spatial database of Holocene volcanic vents in the western conterminous U.S., field mapping and characterization of Holocene rhyolitic tephras at Medicine Lake volcano in northern California, and development of next generation volcano hazard and risk assessments.

Crater Lake partly fills one of the most spectacular calderas of the world, an 8-by-10-km basin more than 1 km deep formed by collapse of the volcano known as Mount Mazama (fig. 1) during a rapid series of explosive eruptions about 7,700 years ago. Having a maximum depth of 594 m, Crater Lake is the deepest lake in the United States. Crater Lake National Park, dedicated in 1902, encompasses 645 km

Crater Lake revealed
Around 500,000 people each year visit Crater Lake National Park in the Cascade Range of southern Oregon. Volcanic peaks, evergreen forests, and Crater Lake’s incredibly blue water are the park’s main attractions. Crater Lake partially fills the caldera that formed approximately 7,700 years ago by the eruption and subsequent collapse of a 12,000-foot volcano called Mount Mazama. The caldera-forming

2018 update to the U.S. Geological Survey national volcanic threat assessment
When erupting, all volcanoes pose a degree of risk to people and infrastructure, however, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. Assessing the relative threats posed by U.S. volcanoes identifies which volcanoes warrant the greatest risk-mitigation efforts by the U.S. Geological Survey and its partners. This update
