Mauna Loa volcano (Hawai'i): HVO weekly report
Over the past week, HVO recorded 47 small-magnitude earthquakes on the Mauna Loa's summit and upper-elevation flanks. Most of these earthquakes occurred at shallow depths of less than 8 kilometers (~5 miles) below ground level, with the largest measuring magnitude 2.1 on the volcano's northwest flank. There is continued slow summit inflation, which HVO state it consistent with magma supply to the volcano's shallow storage system. Gas concentrations and fumarole temperatures remain stable. ...
