Volcano Science Center
Find U.S. Volcano
The Volcano Science Center is the primary center serving the mission of the USGS Volcano Hazards Program — to enhance public safety and minimize social and economic disruption from volcanic unrest and eruption. The center is home to the five US volcano observatories with offices in Anchorage, Alaska; Menlo Park and Mountain View, California; Vancouver, Washington; and Hilo, Hawaii.

Introduction to recommended capabilities and instrumentation for volcano monitoring in the United States
IntroductionThe National Volcano Early Warning System (NVEWS) was authorized and partially funded by the U.S. Government in 2019. In response, the U.S. Geological Survey (USGS) Volcano Hazards Program asked its scientists to reflect on and summarize their views of best practices for volcano monitoring. The goal was to review and update the recommendations of a previous report (Moran and others, 20
Seismic techniques and suggested instrumentation to monitor volcanoes
IntroductionChanges in the pressure or location of magma can stress or break surrounding rocks and trigger flow of nearby waters and gases, causing seismic signals, such as discrete earthquakes and tremor. These phenomena are types of seismic unrest that commonly precede eruption and can be used to forecast volcanic activity. Mass movements at the surface, including avalanches, debris flows, and l
Special topic—Rapid-response instrumentation
IntroductionBased on the reports of Ewert and others (2005, 2018) and Moran and others (2008), most U.S. volcanoes are currently under-monitored and are likely to remain so until the goals of the National Volcano Early Warning System are fulfilled. In addition, volcanoes determined to have low to moderate threat levels (Ewert and others 2005, 2018) could awaken suddenly and, as a result, may need

How are lava flows mapped in Hawaii?
Lava flow mapping provides situational awareness of volcanic eruptive hazards in Hawaii. During eruptions, USGS Hawaiian Volcano Observatory (HVO) scientists employ a variety of techniques to collect and disseminate map data depicting key eruptive features, especially lava flows.
Mining and mineralization of the Clear Lake region
The Geysers-Clear Lake area has been one of the most productive in the United States for mercury, and gold was mined in the late 1800s. Many of the deposits are directly associated with outcrops of early Clear Lake volcanic rocks.
Geology and History of Black Rock Desert Volcanic Field
Black Rock Desert volcanic field is the northernmost volcanic field in a belt of young volcanic fields beginning in the northern Grand Canyon of Arizona and continuing in a north-trending line through Utah. Part of the eastern Basin and Range Province, the Black Rock Desert volcanic field covers nearly 7,000 km2 (2,700 mi) and is 145 km (90 mi) long.
