April 11, 2026—HVO monitoring network outage
On Saturday, April 11, the USGS Hawaiian Volcano Observatory (HVO) noted an outage of its radio telemetry network, resulting in the loss of multiple monitoring data streams. HVO is working to rectify the problem as soon as possible, and staff continue tracking several unaffected data streams to maintain watch over Kīlauea and Mauna Loa volcanoes.
Monitoring data transmitted via the Island of Hawai‘i's cellular network are still being collected and relayed to the web as normal, and these data show no significant changes at any of the island's volcanoes as of 11:00 p.m. HST on April 11.
The three Kīlauea summit live-stream cameras are among the stations unaffected by this outage; they remain online.
During the outage, HVO will continue to report on volcanic activity through official notifications distributed via the Volcano Notification Service.
