Officials are monitoring increased seismic activity and rockfall risks at Hawaii's Kīlauea volcano, leading to temporary trail closures at Hawaiʻi Volcanoes National Park. Over 200 shallow earthquakes were recorded near the summit, prompting the closure of 1.3 miles of trails due to safety concerns. The US Geological Survey maintains an ORANGE aviation color code for Kīlauea, indicating heightened volcanic activity and potential hazards.

Story summary
The U.S. Geological Survey (USGS) issued a volcanic activity notice this week for Kīlauea volcano in Hawaiʻi Volcanoes National Park, reporting renewed spattering at two vents after recent seismic activity beneath its summit. In response, the National Park Service (NPS) announced Wednesday that 1.3 miles of trails, including parts of Halemaʻumaʻu Trail and Byron Ledge Trail, would temporarily close due to heightened concerns about rockfalls and increased seismic activity. Over 200 shallow earthquakes were recorded beneath Kīlauea’s summit over the past week, with a notable magnitude-3.4 earthquake on September 30 causing small rockfalls along the caldera's north wall. As of Thursday, Kīlauea remained at an ORANGE aviation color code, indicating heightened volcanic activity and potential eruption risks.
