Mauna Loa volcano (Hawai'i): HVO weekly report
Friday Jan 24, 2020 23:31 PM | BY: MATTHEW
Mauna Loa caldera, image captured from HVO's MLcam (C) U.S. Geological Survey
During the past week, HVO seismometers recorded 99 small magnitude earthquakes beneath the upper elevations of the volcano; the strongest was a magnitude-3.1 earthquake on January 21. Most earthquakes occurred at shallow depths of less than 5 km (~3 miles) beneath the volcano's surface.
Global Positioning System (GPS) measurements show continued slow summit inflation, consistent with magma supply to the volcano's shallow storage system.
Gas concentrations at the Sulphur Cone monitoring site on the Southwest Rift Zone remain stable. Fumarole temperatures as measured at both Sulphur Cone and the summit have not changed significantly.
