Kilauea volcano (Hawai'i): moderate earthquake on south flank
Tue, 2 Feb 2021, 07:5007:50 AM | BY: MARTIN
Seismic station of the Hawaiian Volcano Observatory (HVO) recorded a volcano-tectonic earthquake with magnitude M 4.1 located beneath the southern flank of the volcano at depth 6 km (4 miles) at about 14:09 local time yesterday. The earthquake was centered about 13 km (8 miles) south of Fern Forest, near the Hōlei Pali area of Hawai'i Volcanoes National Park with weak to light shaking that has been reported across the Island of Hawai'i.

According to HVO scientist, David Phillips, the earthquake had no impact on the ongoing effusive eruption at Kīlauea's summit.
Residents should be aware that possible aftershocks may be felt.
Kīlauea's south flank has been the site of over 30 earthquakes of magnitude-4.0 or greater during the past 20 years. Most are caused by abrupt motion of the volcano's south flank, which moves to the southeast over the oceanic crust. The location, depth, and waveforms recorded as part of today's earthquake are consistent with motion along the south flank detachment fault.
