Photo & Video Chronology —Photographs and videos from field investigations plus webcam imagery of notable events. All images include descriptive captions. Webcams —Near-real-time images from webcams located on Kīlauea's East Rift Zone and Summit.

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.

Image Galleries —Galleries of images and events with expanded descriptions. The Kīlauea Photo and Video Chronology and Mauna Loa Photo and Video Chronology webpages also feature photos. Webcams—Near-real-time images from webcams. Videos—Collection of videos recorded during field excursions or caught on our webcams.

The webcams are operational 24/7 and faithfully record the dark of night if there are no sources of incandescence or other lights. Thermal webcams record heat rather than light and get better views through volcanic gas. At times, clouds and rain obscure visibility. The cameras are subject to sporadic breakdown, and may not be repaired immediately.

Hawaiian Volcano Observatory webcams show current conditions on Hawaiian volcanoes.

HVO, unique among U.S. volcano observatories, has the USGS responsibility to record and report on the thousands of earthquakes that occur every year in Hawaii, mostly beneath the Island of Hawai‘i. The HVO seismic-monitoring network is part of the USGS Advanced National Seismic System (ANSS).
