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.

More than 500 volcanic vents have been identified in the State of California. At least 76 of these vents have erupted, some repeatedly, during the past 10,000 yr. Past volcanic activity has ranged in scale and type from small rhyolitic and basaltic eruptions through large catastrophic rhyolitic eruptions. Sooner or later, volcanoes in California will erupt again, and they could have serious impact

Database for volcanic processes and geology of Augustine Volcano, Alaska
Augustine Island (volcano) in lower Cook Inlet, Alaska, has erupted repeatedly in late-Holocene and historical times. Eruptions typically beget high-energy volcanic processes. Most notable are bouldery debris avalanches containing immense angular clasts shed from summit domes. Coarse deposits of these avalanches form much of Augustine's lower flanks. This geologic map at 1:25,000 scale depicts theAuthorsJacqueline McIntire, David W. Ramsey, Evan Thoms, Richard B. Waitt, James E. BegetDatabase for the Quaternary and Pliocene Yellowstone Plateau Volcanic Field of Wyoming, Idaho, and Montana
The superlative hot springs, geysers, and fumarole fields of Yellowstone National Park are vivid reminders of a recent volcanic past. Volcanism on an immense scale largely shaped the unique landscape of central and western Yellowstone Park, and intimately related tectonism and seismicity continue even now. Furthermore, the volcanism that gave rise to Yellowstone's hydrothermal displays was only paAuthorsRichard D. Koch, David W. Ramsey, Robert L. ChristiansenNewberry Volcano—Central Oregon's Sleeping Giant
Hidden in plain sight, Oregon's massive Newberry Volcano is the largest volcano in the Cascades volcanic arc and covers an area the size of Rhode Island. Unlike familiar cone-shaped Cascades volcanoes, Newberry was built into the shape of a broad shield by repeated eruptions over 400,000 years. About 75,000 years ago a major explosion and collapse event created a large volcanic depression (calderaAuthorsJulie M. Donnelly-Nolan, Wendy K. Stovall, David W. Ramsey, John W. Ewert, Robert A.

The Bend 30- x 60-minute quadrangle has been the locus of volcanism, faulting, and sedimentation for the past 35 million years. It encompasses parts of the Cascade Range and Blue Mountain geomorphic provinces, stretching from snowclad Quaternary stratovolcanoes on the west to bare rocky hills and sparsely forested juniper plains on the east.

The United States is one of the most volcanically active countries in the world. According to the global volcanism database of the Smithsonian Institution, the United States (including its Commonwealth of the Northern Mariana Islands) is home to about 170 volcanoes that are in an eruptive phase, have erupted in historical time, or have not erupted recently but are young enough (eruptions within thAuthorsMarianne Guffanti, Angela K.

Since 1979, Earth scientists of the Geothermal Research Program of the U.S. Geological Survey have carried out multidisciplinary research in the Cascade Range. The goal of this research is to understand the geology, tectonics, and hydrology of the Cascades in order to characterize and quantify geothermal resource potential. A major goal of the program is compilation of a comprehensive geologic mapAuthorsKathryn Nimz, David W. Ramsey, David R. Sherrod, James G. SmithEruptive history and tectonic setting of Medicine Lake Volcano, a large rear-arc volcano in the southern Cascades
Medicine Lake Volcano (MLV), located in the southern Cascades ∼ 55 km east-northeast of contemporaneous Mount Shasta, has been found by exploratory geothermal drilling to have a surprisingly silicic core mantled by mafic lavas. This unexpected result is very different from the long-held view derived from previous mapping of exposed geology that MLV is a dominantly basaltic shield volcano. DetailedAuthorsJulie M.

INTRODUCTION The area covered by this map includes parts of four U.S. Geological Survey (USGS) 7.5' topographic quadrangles (Kilauea Crater, Volcano, Ka`u Desert, and Makaopuhi). It encompasses the summit, upper rift zones, and Koa`e Fault System of Kilauea Volcano and a part of the adjacent, southeast flank of Mauna Loa Volcano.

Medicine Lake volcano (MLV) is a very large shield-shaped volcano located in northern California where it forms part of the southern Cascade Range of volcanoes. It has erupted hundreds of times during its half-million-year history, including nine times during the past 5,200 years, most recently 950 years ago. This record represents one of the highest eruptive frequencies among Cascade volcanoes anAuthorsJulie M. Donnelly-Nolan, Manuel Nathenson, Duane E. Champion, David W. Ramsey, Jacob B.

Landslides, worldwide and in the United States, are arguably the most costly natural hazard. Substantial landslide information is available, but much of it remains underutilized, as a disconnect exists among geologists, decision makers, and the public. The lack of a national landslide insurance policy exacerbates this situation and promotes litigation as the principal recourse for recouping landslAuthorsDavid G. Howell, Earl E. Brabb, David W.
