HAWAIIAN VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Thursday, August 22, 2024, 1:40 AM HST (Thursday, August 22, 2024, 11:40 UTC)

KILAUEA (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

On Thursday, August 22, 12:52 a.m. HST, a magnitude-4.7 earthquake occurred 9 mi (15 km) south of Fern Forest on the Island of Hawaiʻi at a depth of 4 mi (7 km) below sea level. The earthquake had no apparent impact on either Mauna Loa or Kīlauea volcanoes.

Most earthquakes in this region are caused by abrupt motion of Kīlauea 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 slip along faults related to the south flank detachment fault.

The USGS Hawaiian Volcano Observatory continues to monitor Hawaiian volcanoes for any changes.
