There are approximately 1, potentially active volcanoes around the world. VDAP works to reduce loss of life and property, limit economic impact and prevent volcanic crises from becoming disasters. Volcanic eruptions occur int he State about as frequently as the large San Andreas Fault Zone earthquakes.
California's "watch list" volcanoes are dispersed throughout the State and future eruptions are inevitable—the likelihood of renewed volcanism is on the order of one in a few hundred to one in a few thousand annually. The United States has active volcanoes. More than half of them could erupt explosively, sending ash up to 20, or 30, feet where commercial air traffic flies. USGS scientists are working to improve our understanding of volcano hazards to help protect communities and reduce the risks.
To increase to increase public awareness during Native American Indian National Heritage Month, we will be discussing the anthropology of indigenous peoples in the Aleutian Islands and how continued scientific research can help future forecasting of mega-earthquake and transoceanic tsunami probabilities.

Most earthquakes and volcanic eruptions do not strike randomly but occur in specific areas, such as along plate boundaries.
One such area is the circum-Pacific Ring of Fire , where the Pacific Plate meets many surrounding tectonic plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
