Plot showing the distance between two GPS stations on Mauna Loa from February 2022 to November 2023. Station MOKP is on the north side of Mokuʻāweoweo and station MLES is east of Mokuʻāweoweo. This plot shows how the distance between these two stations increased before the 2022 Mauna Loa eruption, indicating that the volcano was inflating.

Map showing the locations of earthquakes beneath Mauna Loa between October 31, 2023, and November 9, 2023. The earthquake colors indicate their depth. Most earthquakes have occurred at depths of 40–60 km (25–37 mi) beneath Mokuʻāweoweo, though some have occurred at shallower depths within 16 km (10 mi) of the ground surface. USGS map.

A view of Moku‘āweoweo (Mauna Loa's summit caldera) from the rim on the northwest side. The lava flows that flooded much of the caldera floor during the brief summit phase of the 2022 eruption are nearly indistinguishable from previous lava flows.

The Northeast Rift Zone eruption of Mauna Loa continues with a major change overnight. The fissure 3 (F3) vent continues to erupt but the supply of lava appears to be much reduced this morning. Lava is overtopping channels near the vent with flows extending no farther than 2.5 mi (4 km) from the vent.
