Research, monitoring, communication. Every day is #EarthDay at the USGS. Volcano monitoring and research conducted at the five US volcano observatories advances our understanding of active volcanoes and hazards, and enables the USGS Volcano Hazards Program to provide information and warnings of volcanic activity in the United States. Each observatory is assigned a geographic area of responsibility (Alaska, Hawaii, California, Cascade Range, Yellowstone). The observatories and their partner organ

Today (August 6) started early for Hawaiian Volcano Observatory scientists. Vigorous lava fountaining associated with episode 30 of the ongoing Halemaʻumaʻu eruption of Kīlauea volcano, Hawaii, began at 1:20 a.m. local time, and HVO geologists were immediately on site to collect data. Once the day dawned, the work included a helicopter trip to the caldera floor to sample lava for chemical analysis. That information can be used to better understand the conditions in the magma chamber, and therefo

USGS Hawaiian Volcano Observatory geologists observed lava roiling in the north and south vents at the summit of Kīlauea on Friday, November 21. Shortly after, lava flowed onto Halemaʻumaʻu crater floor for the first time since episode 36 (November 9). That activity continued through the weekend, with 73 overflows total. Over the past 24 hours, Kīlauea summit deflated and the overflows stopped, causing the forecast window for episode 37 to be adjusted slightly later in time. Episode 37 could occ

The folks at the USGS Hawaiian Volcano Observatory (HVO) do such an awesome job covering the volcanoes of our 50th State. I've often said they provide what amounts to a veritable college level course in volcanology through their beautifully done reports and updates. The following is a collection of videos of the ongoing Kilauea eruption which is occurring deep in the volcano's "caldera" (see the definition of a "caldera" below). That the eruption is taking place in the "caldera" is why the molte
