Map of the Mauna Loa 2022 eruptive fissures, shown as red lines. Red shaded area indicates lava flows produced during the eruption, around the fissure vent areas. Solid white line indicates mapped outer caldera boundary. White dotted line indicates inferred outer caldera boundary that is buried by historic Mauna Loa lava flows. Fissures on map were documented by C.

Seismic nodes are prepared to be deployed to Kīlauea summit on April 17 as part of the Kīlauea Seismic Imaging Project. The nodes will be temporarily placed on the surface of Kīlauea's summit region for the next two months and will collect data that will outline the geometry and nature of the magma system beneath Kīlauea summit.
