The Hawaiian Volcano Observatory recorded 105 small-magnitude earthquakes on Mauna Loa's summit and upper-elevation flanks over the past week. Most of these earthquakes occurred at shallow depths of less than 8 kilometers (~5 miles) below ground level.

There is continued slow summit inflation, consistent with magma supply to the volcano's shallow storage system. Gas concentrations and fumarole temperatures at the Summit and Sulphur Cone monitoring sites remain stable (below 2 ppm SO2, ~98 C respectively). Webcams show no changes to the landscape.
