The 2022 eruption of the Mauna Loa volcano cut off road access to the Mauna Loa Baseline Observatory. Construction on the temporary Mauna Loa Access road was completed on 26 March, 2026.
At this time, there is no site access for the general public to the Mauna Loa Observatory and NOAA has not yet established a public opening date. GML and scientific partners are working together to bring mission critical scientific projects back online. It is still unclear when utility infrastructure will be replaced and power re-established to the site.
We will provide another update as more information becomes available.

What does this program measure?
USGS & HVO Operate digital telemetry receiver and repeater equipment for monitoring seismic and other activity from the flanks of Mauna Loa Volcano. Signals from the western and northern parts of Hawaii Island will be collected at Mauna Loa Observatory and relayed to the Hawaiian Volcano Observatory in Hawaii National Park.
How does this program work?
A computer will collect data from remote sites via the 5.8 GHZ radio. The data from the computer will be transmitted to the Hawaiian Volcano Observatory via the internet. Instruments include digital telemetry receiver and repeater equipment, operating continuously at MLO.
Why is this research important?
To monitor activity from the flanks of Mauna Loa Volcano and collect signals from the west and north parts of Hawaii Island.
Are there any trends in the data?
How does this program fit into the big picture?
What is it's role in global climate change?
