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?
The Global Fallout Program instituted a global network of sampling sites to determine the global transport and fate of radionuclides released into the atmosphere during the testing of nuclear weapons. In recent years, the program focused on the global deposition of the naturally occurring radionuclides, beryllium-7 and lead-210.
How does this program work?
A funnel attached to an ion-exchange column. The project sampled quarterly at Mauna Loa.
Why is this research important?
Are there any trends in the data?
