USGS California Volcano Observatory Opens
The Volcano Hazards Program is excited to announce the establishment of the USGS California Volcano Observatory (CalVO), which expands and replaces the former Long Valley Observatory. The establishment of CalVO, headquartered within existing USGS facilities in Menlo Park, California, will increase awareness of and resiliency to the volcano threats in California and Nevada. A newly designed CalVO website includes information about the new Observatory and all the volcanoes it monitors.Hawaiian Volcano Observatory Celebrates 100 years
The USGS Hawaiian Volcano Observatory (HVO) is celebrating its 100th anniversary in 2012. Volcano monitoring began when Thomas A. Jaggar, Jr., of the Massachusetts Institute of Technology founded HVO in the, then, U.S. territory of Hawai‘i. HVO became a permanent part of the USGS in 1947, and today the USGS Volcano Hazards Program monitors volcanoes across the United States. For more information, please visit the Hawaiian Volcano Observatory website.
