USGS HVO Press Release - Earthquake Causes Part of Kīlauea Caldera Rim to Collapse

Release Date:

A magnitude-3.8 earthquake shook the Kīlauea summit region at 2:55 p.m. Wednesday afternoon.

The earthquake was located 1.3 km (0.8 mi) southeast of Hawai‘i Volcanoes National Park visitor center at a depth of 0.9 km (0.54 mi). Felt reports were received from the National Park and Volcano communities.

A small portion of the caldera wall at Waldron Ledge collapsed during the earthquake. U.S. Geological Survey geologists had earlier identified this section of the caldera wall as unstable and advised the National Park Service to close the area to visitors. Heeding the advice of the USGS, the National Park Service had diverted the crater rim trail away from the edge of the caldera and closed the area several months ago, well in advance of today's earthquake. No injuries were reported.

Daily updates about ongoing eruptions, recent images and videos of summit and East Rift Zone volcanic activity, maps, and data about recent earthquakes in Hawaii are posted on the HVO website at https://volcanoes.usgs.gov/observatories/hvo
