HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey

KAMA’EHUAKANALOA (VNUM #332000)
18°55’12” N 155°16’12” W, Summit Elevation -3199 ft (-975 m)
Current Volcano Alert Level: UNASSIGNED
Current Aviation Color Code: UNASSIGNED

Activity Summary: Kamaʻehuakanaloa volcano (formerly Lōʻihi Seamount), offshore to the southeast of the Island of Hawaiʻi, entered a period of heightened seismic unrest around 2:00 a.m. HST on Monday, January 21. Seismicity ceased by 8 a.m. HST and a continuation of earthquake swarm activity at this time seems unlikely. There were 16 total earthquakes identified in this swarm, all with magnitude 0 and smaller at depths of 8 to 20 miles below sea level. The USGS has so far received no felt report from the Island of Hawaiʻi for any of these events.

Elevated seismicity at Kamaʻehuakanaloa did not impact other volcanoes or any infrastructure on the Island of Hawaiʻi. The source of the earthquakes is difficult to determine at this time, but it may be related to the movement of magma beneath Kamaʻehuakanaloa. Prior swarms related to probable eruptions at the volcano have consisted of thousands of earthquakes over days to weeks. Eruptive activity at this volcano would have no impact on residents of the Island of Hawaiʻi.

The Hawaiian Volcano Observatory continues to monitor Kamaʻehuakanaloa, and will issue further updates as needed for any significant changes in activity.

The Hawaiian Volcano Observatory is one of five volcano observatories within the U.S. Geological Survey and is responsible for monitoring volcanoes and earthquakes in Hawaiʻi and American Samoa.
