HAWAIIAN VOLCANO OBSERVATORY INFORMATION STATEMENT
HAWAIIAN VOLCANO OBSERVATORY INFORMATION STATEMENT
On Friday, February 9, 10:06 a.m. HST, a magnitude-5.7 earthquake occurred 2 km (1.25 mi) southwest of Pāhala on the Island of Hawaiʻi at a depth of 37 km (23 mi) below sea level. The earthquake had no apparent impact on either Mauna Loa or Kīlauea volcanoes. Numerous aftershocks have been felt and are expected to continue. This earthquake is likely associated with lithospheric flexure caused by the weight of the Hawaiian Islands on the oceanic lithosphere. The USGS Hawaiian Volcano Observatory continues to monitor Hawaiian volcanoes for any changes.
