HAWAIIAN VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Saturday, July 6, 2024, 9:28 PM HST (Sunday, July 7, 2024, 07:28 UTC)

KILAUEA VOLCANO (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 Saturday, July 6, 8:47 p.m. HST, a magnitude-4.1 earthquake occurred 9 mi (14 km) south of Fern Forest on the Island of Hawaiʻi at a depth of 4 mi (7 km) below sea level. It was followed by three aftershocks in a similar area within 10 minutes: a M2.0, M2.6 and one M3.3; other aftershocks are possible. 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.
