HAWAIIAN VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Saturday, September 14, 2024, 5:07 PM HST (Sunday, September 15, 2024, 03:07 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 Saturday, September 14, 4:25 p.m. HST, a magnitude-4.3 earthquake occurred 4 mi (6 km) south-southwest of Volcano on the Island of Hawaiʻi at a depth of 0.2 mi (0.3 km) below sea level. The earthquake had no apparent impact on either Mauna Loa or Kīlauea volcanoes.  

The size, location, and character of this earthquake suggests that it is related to the ongoing pressurized magma storage system beneath Kīlauea’s summit area, which extends into the upper East Rift Zone, where intrusions of magma have recently occurred. Several aftershocks were detected within the first 30 minutes after the earthquake, as is typical for an event of this size.  Additional aftershocks are expected to be minor, but may continue for day to weeks. 

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