By Hawaiian Volcano Observatory April 18, 2023

During the week of April 10, the Hawaiian Volcano Observatory upgraded the Hualālai Repeater station and installed a new webcam looking at the northwest flank of Mauna Loa.

At the Hualālai Repeater site, HVO technicians installed new batteries as well as a new electronics system and box. They also installed a new webcam, the HLcam, which views Mauna Loa's northwest flank from Hualālai: [HLcam] - Mauna Loa's northwest flank from Hualālai volcano | U.S. Geological Survey (usgs.gov).

During the week of April 10, Hawaiian Volcano Observatory technicians upgraded the Hualālai repeater site, which is an important telemetry hub for volcano monitoring data. The site is located on the southeast side of Hualālai, at an elevation of 2,160 meters (7,090 feet) above sea level. This photo, taken after the upgrades were completed, shows the site enshrouded in fog. Upgrades included replacing the batteries, installing a new electronics system and box, and installing a new webcam looking at Mauna Loa (HLcam: [HLcam] - Mauna Loa's northwest flank from Hualālai volcano | U.S. Geological Survey (usgs.gov)). The station upgrades and new webcam were funded by the USGS Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157, provided in response to Kīlauea’s 2018 lower East Rift Zone eruption and summit collapse).

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.
