More than 23,000 people were killed in Armero (left) when lahars swept down
from the erupting Nevado del Ruiz volcano. When the volcano became restless
in 1984, no team of volcanologists existed that could rush to the scene of
such an emergency to provide a wide range of assistance. Less than a year after this disaster, however, the USGS and the U.S. Office of Foreign Disaster Assistance (OFDA) put together a team of volcano specialists and a cache of equipment that could be quickly dispatched to an awakening volcano if needed. |
A mobile volcano-response team that helps to saves lives in a volcano crisis.
Following the disastrous eruption of Nevado del Ruiz volcano, Colombia, that killed more than 23,000 people in 1985, the U.S. Geological Survey and U.S. Office of Foreign Disaster Assistance developed the Volcano Disaster Assistance Program (VDAP) to respond to selected volcanic crises around the world. The goal of VDAP is to reduce fatalities and economic losses in countries experiencing a volcano emergency. At the request of host countries and working through USAID, an experienced team of USGS and other scientists can rapidly respond to developing volcanic crises with a state-of-the-art portable cache of monitoring equipment. VDAP has proven to be effective in saving lives and property by assistance provided to local scientists for determining the nature and possible consequences of volcanic unrest and communicating eruption forecasts and hazard-mitigation information to local authorities. VDAP is the only rapid-response volcano crisis team in the world. VDAP's most notable success occurred during the catastrophic eruptions of Mount Pinatubo in the Philippines in 1991. A quick response by VDAP and Philippine scientists to developing unrest resulted in rapid establishment of a monitoring network and completion of a hazard assessment, accurate eruption forecasts, and effective communication with Philippine Government officials and US military leaders. Evacuations and other civil-defense actions saved thousands of lives and hundreds of millions of dollars of US military aircraft and hardware. Since the 1991 eruption of Mount Pinatubo, VDAP has responded to many volcano crises in Central and South America, the Caribbean, Africa. Asia, and the South Pacific. The new volcano-monitoring techniques developed by USGS scientists and the experience gained by VDAP scientists responding to volcano crises overseas help scientists to better protect people's lives and property from future eruptions of volcanoes in the United States. These international volcano responses enable scientists to test and refine monitoring methods and to increase their application for domestic volcanic crises. |
