What are supportive agencies & rescue teams to save lives from volcano eruption?

Answer 1

This varies from country to country--especially the rescue agencies. However, the USGS and Office of Federal Disaster Assistance have a special team to assess and monitor hazards to help emergency management agencies and rescue teams make decisions about the best ways to save lives. It is called the Volcano Disaster Assistance Program and provides help around the world.
"The world's only volcano crisis response team, organized and operated by the USGS, can be quickly mobilized to assess and monitor hazards at volcanoes threatening to erupt. Since 1986, the team has responded to more than a dozen volcano crises as part of the Volcano Disaster Assistance Program (VDAP), a cooperative effort with the Office of Foreign Disaster Assistance of the U.S. Agency for International Development. The work of USGS scientists with VDAP has helped save countless lives, and the valuable lessons learned are being used to reduce risks from volcano hazards in the United States. " The VDAP teams have responded to volcanic events in the U.S., Latin America, Indonesia, Philippines, New Guinea, and the West Indies.
