Precursory gas-pistoning cycles of low dome fountains and ponding of lava followed by drainback are continuing every half hour since 8:00 am HST. Small lava flows occurred during some of the cycles. Episode 21 fountains are expected today. View All Messages.

Dome fountaining and filling of the north vent began again just before 9:00 am HST. This is the third gas-piston cycle (30 minutes apart) marked by low dome fountains, lava filling the north vent, an increase in tremor, and drainback. View All Messages.

The dome fountains were associated with two 5-10 minute periods of gas-pistoning associated with elevated tremor. The first began at 8 am HST and the second at 8:30 am HST. The start of major fountaining is likely to begin later today. View All Messages.

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.
