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.

The progression of basaltic–rhyolitic melt storage at Yellowstone Caldera
Yellowstone Caldera is one of the largest volcanic systems on Earth, hosting three major caldera-forming eruptions in the past two million years, interspersed with periods of less explosive, smaller-volume eruptions1. Caldera-forming eruptions at Yellowstone are sourced by rhyolitic melts stored within the mid- to upper crust. Seismic tomography studies have suggested that a broad region...
Seismic velocity changes from repetitive seismicity at Mauna Loa prior to and during its 2022 eruption
Mauna Loa’s short-lived eruption from late November to early December 2022 marked the culmination of nearly a decade of elevated seismic activity and geodetic inflation. The volcano has been monitored by a network of permanent, short period and broadband seismometers. I used the continuous waveform data from that network starting in 2012 to generate a catalog of seismicity that enhances...

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.
