[F1cam] - Kīlauea Caldera Thermal from HVO Observation Tower

The webcams are operational 24/7 and faithfully record the dark of night if there are no sources of incandescence or other lights. Thermal webcams record heat rather than light and get better views through volcanic gas. At times, clouds and rain obscure visibility. The cameras are subject to sporadic breakdown, and may not be repaired immediately. Some cameras are

[KIcam] Kīlauea Caldera from HVO Observation Tower

This image is from a research camera mounted in the observation tower at the Hawaiian Volcano Observatory. The camera is looking SSE towards the active vent in Halemaʻumaʻu, 1.9 km (1.2 miles) from the webcam. For scale, Halemaʻumaʻu is approximately 1 km (0.6 mi) across and about 85 m (~280 ft) deep.

[MTcam] Mokuʻāweoweo Caldera Thermal from the Northwest Rim

This image is from a temporary thermal camera located on the north rim of Mauna Loa's summit caldera. The temperature scale is in degrees Celsius up to a maximum of 500 degrees (932 degrees Fahrenheit) for this camera model, and scales automatically based on the maximum and minimum temperatures on the caldera floor and not the whole frame, which sometimes results in the

Slope map of Mauna Loa, including lava flows erupted since 1823 (gray), showing the approximate number of hours or days it took for a flow to advance from the vent location to the ocean or maximum reach of a flow. One flow that moved down the steep slopes on west flank of Mauna Loa reached the ocean in as little as 3 hours after the vent started erupting in 1950. The bold

[K2cam] Halemaʻumaʻu Overlook Vent from HVO Observation Tower

This image is from a research camera mounted in the observation tower at the Hawaiian Volcano Observatory. The camera is looking SSE towards the active vent in Halemaʻumaʻu, 1.9 km (1.2 miles) from the webcam. For scale, the crater wall of Halemaʻumaʻu behind the eruptive vent is about 85 m (~280 ft) high.
