Summit, Moku‘āweoweo Caldera

Mokuʻāweoweo Caldera [MLcam]

From the Northwest Rim 

This image is from a temporary research camera positioned on the north rim of Mokuʻāweoweo, the summit caldera of Mauna Loa volcano by the USGS Hawaiian Volcano Observatory. If you look carefully around early morning or late evening, you may see a few thermal areas emitting steam. See 'Current Activity' for the latest Mauna Loa information.

Mokuʻāweoweo Caldera Thermal [MTcam]

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 rim (bottom of image) looking saturated (white). Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures.

From South Rim 

This image is from a research camera positioned on the south rim of Mokuʻāweoweo, Mauna Loa's summit caldera, in Hawaiʻi Volcanoes National Park. The camera looks north-northwest, focusing on the southern part of the caldera. The 1940 cone is just right of center; the 1949 cone is on the caldera rim at left. The high point of Mauna Loa's summit is in the background.

South Pit [SPcam]

From South Rim 

This image is from a research camera positioned on the south rim of Mokuʻāweoweo, Mauna Loa's summit caldera, in Hawaiʻi Volcanoes National Park. The camera looks west-southwest, across South Pit, focusing on the south part of Mauna Loa's summit region and upper Southwest Rift Zone.

Northeast Rift Zone 

Mauna Loa's Northeast Rift Zone [M1cam]

From HVO Observation Tower

This image is from a research camera positioned in the observation tower at the Hawaiian Volcano Observatory. The camera looks northwest toward the summit and Northeast Rift Zone of Mauna Loa.

Southwest Rift Zone 

The Middle Part of Mauna Loa's Southwest Rift Zone [M2cam]

This image is from a research camera positioned on a cone in Mauna Loa's Southwest Rift Zone in Hawaiʻi Volcanoes National Park. The camera looks northeast (upslope), focusing on the middle part of the Southwest Rift Zone. The volcano's summit is at upper right.

The Upper Part of Mauna Loa's Southwest Rift Zone [M3cam] 

This image is from a research camera positioned on a cone in Mauna Loa's Southwest Rift Zone in Hawaiʻi Volcanoes National Park. The camera looks northeast (upslope), focusing on the upper part of the Southwest Rift Zone. The upper flank of Mauna Loa forms the skyline.

Disclaimer

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 observing an area that is off-limits to the general public because of significant volcanic hazards.
