Mauna Loa

This image is from a research camera positioned on Mauna Kea. The camera looks south toward the summit and Northeast Rift Zone of Mauna Loa.

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

GPS campaign survey stations high on the flanks of Mauna Loa offer expansive views of neighboring volcanoes. From this station located west of Mauna Loa summit, Hualālai volcano is visible. Most Mauna Loa GPS campaign survey sites have been occupied every year since 1996, whereas less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years. USGS photo by S.

This video shows a typical day on Mauna Loa, captured from a new webcam looking south towards the volcano. The field of view covers the summit region and much of the Northeast Rift Zone. On clear days, the small gas plume from Kīlauea's summit can sometimes be

Annotated MKcam image, taken on May 29, 2021. The new MKcam is positioned on Mauna Kea with a south view of Mauna Loa summit and Northeast Rift Zone. The MKcam view also includes features on the East Rift Zone and summit of Kīlauea, including Kānenuiohamo, Maunaulu, and the Halema‘uma‘u plume. Kūlani, a cone on the Northeast Rift Zone of Mauna Loa, is also visible in the

On May 15, USGS Hawaiian Volcano Observatory geologists did a routine hike to the summit of Mauna Loa and inspected summit monitoring equipment. Clear weather provided good views across the floor of Moku‘āweoweo, Mauna Loa's summit caldera, and nothing unusual was observed.

On the west side of Mauna Loa summit, a campaign GPS (center-right) measures its location for a period of 2–3 days. This site has been occupied every year by helicopter since 1994. Mauna Kea, Hualālai and Haleakalā can be seen in the distance. USGS photo taken by S. Conway on May 11, 2021, during the 2021 Mauna Loa GPS campaign survey. 

Recently, HVO geophysicists completed the annual high-precision Global Positioning System (GPS) survey of Mauna Loa. The annual survey supplements HVO's continuous GPS monitoring stations and provides information on vertical and horizontal deformation of the ground surface. These measurements inform HVO about the volume changes within subsurface magma reservoirs at Mauna

During the annual Mauna Loa GPS campaign, 33 campaign stations are occupied with GPS instruments for days to weeks. The stations are spread across the flanks of the volcano and provide a synoptic picture of deformation on the volcano over the past year. The location of this survey was on the north flank of Mauna Loa, with clear views of Mauna Kea visible in the background
