Two moderate earthquakes near Mauna Loa volcano, string of aftershocks, Hawai’i
Heightened unrest continues under Mauna Loa, with two moderately strong earthquakes within 24 seconds on October 14, 2022, and a string of aftershocks that are still taking place. The unrest is likely caused by renewed input of magma into Mauna Loa’s summit reservoir system. The Alert Level remains at Advisory and the Aviation Color Code at Yellow.
Seismic activity beneath Mauna Loa increasing, Hawai’i
Seismic activity beneath the Mauna Loa volcano has been gradually increasing over the past 2 months. In addition, a small seismic swarm started on September 23, with most earthquakes in a cluster about 5 km (3.1 miles) wide and -2 to 1 km (-1.2 to 0.6 miles) below the surface. The Aviation Color Code is at Yellow and the Volcano Alert Level at Advisory.
Earthquake swarm beneath Kamaʻehuakanaloa (Lōʻihi) seamount likely the result of magma movement, Hawai’i
The Hawaiian Volcano Observatory (HVO) has detected increased seismic activity beneath Kamaʻehuakanaloa (formerly known as Lōʻihi) seamount, south of the Island of Hawaiʻi over the past few days. The activity is likely the result of magma movement beneath Kamaʻehuakanaloa seamount and currently shows no sign of leading to an eruption. The last eruption at this volcano took place in 1996 (VEI 0).
