Kīlauea & Maunaloa Update, June 3, 2021

Kilauea's gas wanes after its lava lake finishes crusted over, but the volcano shows signs of slowly growing pressure already with increasing earthquakes and ground tilt. We examine the current monitoring signals and webcams courtesy of the USGS Hawaiian Volcano Observatory, before digging into some comparisons of the recent eruption with those in the history books, looking at depth, effusion rates, duration and volume. Next we turn to Maunaloa's monitoring signals, and though quieter than Kīlauea's there is also slightly elevated seismic activity showing signs of continued slow magma filling. As the larger volcano's recent flurries of seismic activity remain in the minds of island residents and preparedness leaders, vacuation plans have been tasked to the state's Hawaiʻi Emergency Management Agency (HIEMA). The USGS HVO have already previously produced lava inundation zone maps for Maunaloa, which we describe and share in the preparedness segment of our update. As usual, we discuss live viewer questions as we switch between topics!
