Photo and Video Chronology – Kīlauea GPS campaign and Mauna Loa summit webcams

By Hawaiian Volcano Observatory November 9, 2023

Hawaiian Volcano Observatory (HVO) geophysicists completed the annual GPS survey of Kīlauea in October 2023. On November 8, 2023, HVO staff fixed the MLcam (visual imagery) and MTcam (thermal imagery); both are located near the summit of Mauna Loa. 

The MLcam and the MTcam are located on the rim of Moku‘āweoweo (Mauna Loa's summit caldera). HVO staff serviced these cameras on November 8, 2023. Both are now transmitting images of Mauna Loa's summit caldera.

On November 8, 2023, Hawaiian Volcano Observatory staff visited the rim of Moku‘āweoweo (Mauna Loa's summit caldera) to service the MLcam and the MTcam. These cameras had been temporarily offline and not transmitting images. View the MTcam here: https://www.usgs.gov/volcanoes/mauna-loa/mtcam-mokuaweoweo-caldera-ther….

The lava flows that flooded much of the caldera floor during the brief summit phase of the 2022 eruption are nearly indistinguishable from previous lava flows.

During the annual Kīlauea GPS campaign, which was completed in October 2023, scientists temporarily deploy a number of GPS instruments at established benchmarks; their recorded positions can be compared with those from previous years to discern subtle patterns of ground deformation associated with volcanic activity.

In this photo, taken on October 3, 2023, near Kīlauea's coastline in Hawai‘i Volcanoes National Park, a GPS antenna is mounted on a fixed rod. A GPS receiver, housed in the yellow box, records the positions that can be compared with those from previous years to discern subtle patterns of ground deformation associated with volcanic activity. These data augment the permanent, continuously recording GPS instruments in HVO's monitoring network. USGS photo by A. Ellis.

Hawaiian Volcano Observatory geophysicists completed the annual GPS survey of Kīlauea. Most Kīlauea and Mauna Loa GPS campaign survey sites have been occupied every year since the early 1990s, whereas the less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years.
