USGS HVO 'M3cam' on Mauna Loa's flanks — high-altitude monitoring above the cloud layer. The November 2022 eruption's dark lava flows are visible as fresh streaks on the older lava field. Summit rises to 13,679 ft; views above the trade-wind inversion on clear days.
USGS HVO 'M2cam' on Mauna Loa's upper flank at ~11,000 ft — Earth's most massive active volcano. High-altitude lava landscape; summit snow possible above 11,000 ft in winter. The 2022 eruption flows are visible as dark streaks on older pāhoehoe in the frame.
USGS HVO 'HLcam' monitoring Mauna Loa's Mokuʻāweoweo summit caldera. Earth's largest active volcano last erupted November–December 2022 — first summit eruption since 1984. Watches for renewed caldera activity and any smoke plumes from the northeast rift zone.
USGS HVO 'MDLcam' on Mauna Loa — mid-elevation monitoring of the volcano's 60-mile-long shield. Watches the summit area and Northeast Rift Zone for signs of renewed magmatic intrusion. Part of the continuous HVO surveillance network active since the observatory's 1912 founding.
USGS HVO 'MK2cam' looking at Mauna Loa from a Mauna Kea vantage. Unique cross-volcano perspective — Mauna Loa's 60-mile-long shield profile against the Pacific horizon. Shows the visual scale difference between the two highest island volcanoes on Earth.
USGS HVO 'MKcam' — Mauna Kea's view across the saddle to Mauna Loa. At 13,679 ft (Mauna Loa) and 13,796 ft (Mauna Kea), Hawaii's twin giants face each other in the frame. Both summits visible above the trade-wind cloud inversion in clear weather.
USGS HVO 'MLcam' watching Mauna Loa's Mokuʻāweoweo caldera from the summit area. During the 2022 eruption this camera captured 200-ft lava fountains and active caldera lava lakes. Now quiet — remains live and ready to document the next eruption cycle.
USGS HVO 'MSPcam' monitoring Mauna Loa's south flank and caldera approach at ~13,000 ft. Above the cloud line most days — watch sunrise turn lava fields gold and summit snowpack build in winter. Monitors the south caldera wall for ground deformation and magmatic unrest signals.
