As of the morning of November 29, lava from the eruption of the Mauna Loa volcano on Hawaii's Big Island has been confirmed to have crossed the access road to NOAA's Mauna Loa Observatory and taken out power lines to the site. These circumstances have resulted in a pause in data being collected at the observatory.
All NOAA staff from the Mauna Loa Observatory are safe.
At this point the facility is not accessible.
NOAA will continue to provide updates as the situation develops.

Mercury is measured via cold vapor atomic fluorescence. Particulate matter is measured with energy dispersive X-ray fluorescence & high resolution magnetic sector field inductively coupled plasma mass spectrometry. Major ions are measured via ion chromatography.
The instruments used include: Tekran Model 2537A Mercury Vapor Analyzer, Tekran Model 1130 Reactive Gaseous Mercury Sampling Unit, Tekran Model 1135 Particulate Mercury Sampling Unit, Tekran Model 2505 Primary Source Calibration Unit.
These instruments are capable of performing automated continuous or semi-continuous collection and analysis of the three forms of atmospheric mercury using the National Exposure Research Laboratories (NERL) methodology.
In order to investigate mechanisms of elemental gaseous mercury oxidation in the free troposphere and to evaluate trans-Pacific transport of mercury species. A goal is to accumulate a long-term record of ambient Elemental Mercury (Hg O), Reactive Gaseous Mercury forms (RGM), and Particulate Mercury (Hg P) chemistry to support atmospheric mercury chemistry research; to establish a baseline mercury measurement station; and to investigate the long range transport of mercury from South East Asia across the Pacific.
It is too early to tell.
