Volcano Watch: Kamaʻehuakanaloa — the volcano formerly known as Loʻihi Seamount

  • USGS map Earthquakes detected by HVO’s seismic network in December 2021, with the size of the circles corresponding the earthquake magnitude and the color corresponding to the earthquake depth. The cluster of mostly blue earthquakes are from a persistent swarm about 30 km (19 miles) underneath Pahala. Kamaʻehuakanaloa’s earthquake swarm was mostly 5–13 km (3–8 miles; yellow) below sea level, with a few shallower events.

The USGS Hawaiian Volcano Observatory monitors 6 volcanoes: Kilauea (currently erupting within Halema‘uma‘u), Mauna Loa (most recent eruption in 1984), Hualalai (most recent eruption in 1801), Haleakala (on Maui; most recent eruption sometime between 1480 to 1600 AD), Maunakea (most recent eruption over 4,000 years ago), and Kama‘ehuakanaloa (most recent activity in 1996).
