Volcano Disaster Assistance Program
The Volcano Disaster Assistance Program (VDAP) was founded by the U.S. Geological Survey and the United States Agency for International Development's Office of U.S. Foreign Disaster Assistance after the eruption of Nevado del Ruiz (Colombia) in 1985. The volcanic eruption melted a glacier triggering a lahar that killed 25,000 people. It was determined that increased monitoring and enhanced communications between scientists and civil authorities would make it easier to evacuate local populations and save lives. Today the program responds to volcanic crises around the world. The aim of the program is to assist in saving lives and property, to reduce economic losses, and to prevent a natural hazard becoming a natural disaster. VDAP staff members are based at the USGS Cascades Volcano Observatory, in Vancouver, Washington. VDAP channels its energy into four main activities: response to natural disaster, capacity building, training, and volcanological research. In 2024, VDAP received the American Geophysical Union's International Award for its sustained effort in volcanic disaster risk reduction.
Response
VDAP responds primarily to ‘non-domestic’ eruptions outside the United States. Since 1986, the team has responded to over 70 major events around the world. Scores of other remote responses involve consultations with the relevant local observatories. A subset of foreign responses are listed in the following table and on the map.
Preparation and Monitoring
Capacity building involves the development of education and monitoring in hazardous areas. VDAP staff install equipment, teach field methods, train on eruption forecasting methods and assess hazards in volcanically active areas. The work is a major focus for VDAP staff and is undertaken around the world.
Training
VDAP holds workshops and training courses around the world. These include volcano seismology, geodesy, remote sensing and Geographic information system (GIS) modelling. VDAP funds and assists the 8-week annual international field course run by the University of Hawaii's CSAV (Center for the Study of Active Volcanism) in Hilo, Hawaii and Vancouver, WA. The students include geologists, geochemists and geophysicists, who receive training in the science behind volcano monitoring.
Research
VDAP supports projects which improve the forecasting of eruptions or better characterize the effects of previous eruptions. Examples of this include research at Pinatubo and Chaitén Volcano, Chile.
