Kīlauea Volcano — Lavafall Near Kapoho Crater

Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall. A side channel makes a short surface diversion before rejoining the existing channel.

July 5, 2018, collapse event at Kīlauea Volcano's summit

Since August 4, 2018, Kīlauea Volcano's summit activity has diminished dramatically. But between mid-May and early August, 62 collapse events occurred, with each releasing energy equivalent to a magnitude-5+ earthquake and causing extensive ground shaking in the summit area. On July 5, 2018, USGS video cameras stationed at various summit locations happened to record one of
