March 5, 2025 — Tephra clast erupting during episode 12 of Kīlauea summit eruption
Detailed Description
During the lava fountains of episode 12, which reached approximately 300 feet (90 meters) high, tephra particles traveled through the air to be deposited on the crater rim down wind. This clast was about 16 inches (40 centimeters) long. The tephra clasts formed during the recent lava fountains are very bubble rich and delicate, breaking easily when they are moved.
