September 8, 2022 — Mauna Loa Sulphur Cone MultiGas Station Maintenance
Detailed Description
At the Sulphur Cone MultiGas station on the Southwest Rift Zone of Mauna Loa, a thermocouple is housed within plastic tubing to protect it from the harsh environment. The thermocouple, which measures temperature, is inserted into a nearby fumarole (an area emitting volcanic gases) to detect subsurface changes in temperature. USGS image by T. Elias.
