Sample details and near-real-time ED-XRF, grain size, and grain shape data collected during the November – December 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi At 11:21 p.m. (Hawaii Standard Time [HST]) on November 27, 2022, Mauna Loa volcano on the Island of Hawaiʻi started erupting from fissures at its summit caldera, Mokuʻāweoweo. This was followed shortly afterwards by the opening of a segment of fissures in the direction of the Southwest Rift Zone. These were mostly within the structural boundary of the caldera, so their location is denoted as ‘South Caldera,’ with the exception of a short fissure that extended into the uppermost Southwest Rift Zone. By November 28, activity had shifted to four fissures that opened in the upper Northeast Rift Zone (Lynn and others, 2023). By December 2, eruptive activity was focused from Northeast Rift Zone fissure 3A supplying lava...
