Hawaiʻi Volcanoes National Park closed Halemaʻumaʻu Trail and part of Byron Ledge Trail, 1.3 miles in all, on October 7 because of continued inflation and increased earthquakes at Kīlauea's summit. The USGS Hawaiian Volcano Observatory counted more than 200 shallow earthquakes in a week; a magnitude 3.4 quake on September 30 caused small rockfalls, and new cracks opened on the caldera floor. Both trails descend from the rim to the floor and have seen dangerous rockfalls before. Viewing areas on the Keanakākoʻi side closed the week before. Scientists say lava fountains could resume; the last eruption was August 25.
