Response Activities, Equipment Repair, and Hardening from the Kīlauea eruption

The USGS will rebuild and harden HVO’s telemetry network, communications network, and computing infrastructure.

  • The USGS will reestablish the HVO network of realtime monitoring instruments at the summit and in critical rift zone areas to support early detection of magma returning to the shallow reservoirs and thus provide accurate hazards characterizations.
  • The USGS will establish Unstaffed Aircraft Systems (UAS) capability to measure volcanic gas flux, conduct photo and other mapping surveys of volcanic features, and to help monitor the summit and rift zones for renewed volcanic activity. The USGS will develop a response plan guide for UAS activities for future eruptions.
