Hawaiian Volcano Observatory Status Report

Sunday, June 30, 2024, 1:43 a.m. Hawaii Standard Time (Sunday, June 30, 2024, 11:43 UTC)
Kilauea (VNUM#332010)
19°25’16” N 155°17’13” W, summit elevation 4091 feet (1247 meters)
Current Volcano Alert Level: Warning
Current Aviation Color Code: Yellow
Event Overview: The Upper East Rift Zone of Kīlauea Volcano below the Crater Link in Hawaii Volcanoes National Park has been experiencing an earthquake swarm since the afternoon of June 27. The intensity of the earthquakes escalated during the evening of June 29, with the rate of earthquakes reaching about 30 per hour. Most of the earthquakes were concentrated in the area between Puhimau Crater and the intersection of Hilina Pali Road at depths of 1.5-3 km (1-1.8 mi), but they also extended north to Keanakāko’i Crater and south to Pauahi Crater. The largest earthquake in the swarm, a magnitude 3.0, occurred at 1:03 a.m. Hawaii Standard Time, just north of Hi’iaka Crater at a depth of 3 km (2 mi). Although the summit area has been swelling since the end of the volcano’s southwest eruption on June 3, 2024, there has been no significant change in ground deformation associated with the increased seismicity.
analyze: Following the June 3, 2024, eruption, magma has been repressurizing storage systems beneath the Halema’uma’u and South Crater areas, triggering earthquakes in the upper East Rift Zone and South Halema’uma’u Crater. At this time, it is uncertain whether this increase in activity will lead to a recent intrusion or eruption, or simply continue as seismic unrest at depth. Previous eruptions and intrusions beneath the upper East Rift Zone have occurred near Pauahi and Hi’iaka craters in the southeast and around Luamanu and Keanakāko’i craters on the crater rim. The area erupted several times in the 1960s and 1970s; the most recent eruption occurred on a single day in November 1979 in and near Pauahi Crater.
Currently, there are no indications that magma is moving toward the June 3, 2024, eruption site southwest of the crater. However, the nature and location of the unrest could change rapidly, and the likelihood of an eruption could change quickly.
renew:The U.S. Geological Survey Hawaii Volcano Observatory (HVO) will continue to provide daily updates on Kilauea. If there are significant changes in volcanic activity, a Volcano Activity Notice will be issued.
