MEXICO – A cluster of several (7) volcanic earthquakes up to magnitudes 2.4 has occurred this morning, perhaps heralding some more vigorous activity in the near future. Apart from this, activity has remained stable with about 2 weak steam-gas-sometimes ash-containing explosions per hour. A steam plume often rises about 1 km above the volcano. Meanwhile, Mauna Loa may be stirring in Hawaii. The large volcanic system last erupted in 1984. The latest update of the USGS mentions that minor inflation of a shallow magma reservoir beneath Mauna Loa may be occurring. Seismicity rates were slightly elevated. However, the level of observed seismicity is far from alarming and the alert level remains at green. No eruption is expected in the near future. From the USGS report: “Deformation of Mauna Loa continued to be dominated by southeasterly motion of the south flank. However, slow, localized uplift also continues near the summit caldera (~1cm/yr at MLSP) suggesting that some inflation of the shallow magma reservoir complex beneath the summit area is occurring. Seismicity: Seismic activity within the southwest rift was slightly above background levels. HVO seismic networks detected 1 shallow event below summit area, 2 mid-crustal events (5-13 km) west and northwest of summit, 8 shallow events within the southwest rift, 1 shallow events on the northeast rift zone.” –Volcano Discovery
