Most of these events occurred at shallow depths of less than 5 kilometers (~3 miles) below ground level, with the strongest earthquake measuring magnitude 2.3 on the morning of March 19. This earthquake was located in the radial vents area west of the summit caldera within the volcano. There is continued summit inflation which HVO assert is due to “consistent with magma supply to the volcano's shallow storage system.” Both gas concentrations and fumarole temperatures remain stable. ![]() Depth of earthquakes under Mauna Loa over the past week (C) U.

Most events occurred at shallow depths of less than 5 kilometers (~3 miles) beneath the surface of the summit and upper flanks of the volcano. There is continuous slow summit inflation which HVO say is “consistent with magma supply to the volcano's shallow storage system.” Gas concentrations ad fumarole temperatures remain stable. Fri, 21 Feb 2020, 14:54 ![]() The location of recorded earthquakes over the past week (C) U.S. Geological Survey HVO recorded 44 small-magnitude earthquakes beneath Mauna Loa volcano's upper elevations. The strongest was a magnitude-2.2 on the 16th of February, at approximately 7 kilometers (around 4 miles) below the surface. This was deeper than most of the earthquakes which occurred at depths of less than 5 kilometers (around 3 miles) beneath the surface of the volcano. The volcano continues to inflate, due to magma being supplied to the volcano’s shallow storage region. Gas concentrations and fumarole temperatures remain stable. ![]() The depth of recorded earthquakes over the past week (C) U.S. Geological Survey Fri, 14 Feb 2020, 21:31 ![]() Mauna Loa caldera, image captured from HVO's MLcam (C) U.S. Geological Survey 31 small-magnitude earthquakes occurred beneath Mauna Loa over the past week.
