Heightened seismic unrest observed at Kamaʻehuakanaloa over six hour period

Kamaʻehuakanaloa volcano (formerly known as the Lōʻihi Seamount), offshore to the southeast of the Island of Hawaiʻi, entered a period of heightened seismic unrest around 2 a.m. HST on Monday, Jan. 21. Seismicity ceased by 8 a.m. HST and a continuation of earthquake swarm activity at this time seems unlikely, according to an update from the Hawaiian Volcano Observatory.
