The USGS Hawaiian Volcano Observatory (HVO) is responsible for monitoring six active volcanoes on the Islands of Hawai‘i and Maui. The Island of Hawai‘i, with four active volcanoes, is liveliest. Between 1912 and 2012, there were nearly 50 Kīlauea eruptions, 12 Mauna Loa eruptions, and one Hualālai intrusion of magma.

Hawaiian lava flows generally advance slowly downslope, and during this eruption flows have been confined to Halemaʻumaʻu crater and the southwest side of Kaluapele, Kīlauea's summit caldera.

Fountains from a vent of the Kilauea volcano on Hawaii's Big Island grew to more than 250 feet (76.2 meters) high Monday night, according to the latest status report from the Hawaiian Volcano ...

HVO monitors earthquakes and the active volcanoes in Hawaii, assesses their hazards, issues warnings, and advances scientific understanding to reduce the impacts of volcanic eruptions. Communicating the results of our work to the public, emergency managers, and the scientific community is an important aspect of the HVO mission.
