HAWAIIAN VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Sunday, April 12, 2026, 7:20 AM HST (Sunday, April 12, 2026, 17:20 UTC)

The USGS Hawaiian Volcano Observatory (HVO) is experiencing a partial monitoring network outage that started around 1:45 p.m. HST on Saturday, April 11. Despite this partial outage, the remaining data coming into HVO are sufficient to allow us to detect major changes at Hawaiian volcanoes.

The outage is affecting monitoring data transmitted via radio telemetry. Monitoring data transmitted via the Island of Hawai‘i's cellular network are still being collected and relayed to the web as normal. This includes the three Kīlauea summit live-stream cameras, which remain online at this time.

HVO staff have been assessing the issue and working to resolve the outage since yesterday afternoon. Restoration of data streams could take hours or days due to the complexity of the problem. Meanwhile, users of the HVO website will notice gaps in seismic and other data streams until the problem is resolved.

HVO continues to monitor Hawaiian volcanoes closely, and we will continue to issue updates on a regular schedule.

The Hawaiian Volcano Observatory is one of five volcano observatories within the U.S. Geological Survey and is responsible for monitoring volcanoes and earthquakes in Hawaiʻi and American Samoa.
