While the largest volcano on Earth — Mauna Loa is not erupting, rates of deformation and seismicity at the summit remain slightly elevated and above long-term background levels. Other Mauna Loa monitoring data streams show no significant change in deformation rates…
Hawaiian Kilauea volcano continues erupting since December 20, 2021, with lava activity confined to the Halemaʻumaʻu crater. On April 15, the lava lake was 227 m (745 feet) deep and remains stagnant over its eastern half. SO2 emission rates remain elevated at 950…
A small swarm of shallow seismicity, that began at 11:00 UTC on March 18, 2021, is occurring beneath the upper Ka‘ōiki seismic zone, under Mauna Loa’s southeast flank and northwest of Kīlauea's summit, Hawaii. Mauna Loa Volcano is not erupting;…
