Volcano Watch: It’s an extraordinary time on Kilauea Volcano

Last week’s Volcano Watch focused on the East Rift Zone eruption, which continues to impact the lower Puna District. Changes in the eruptionare occurring daily, if not hourly, so by the time you read this article, the situation likely will have changed.

Volcano Watch: Explosive eruptions at the summit of Mauna Loa — when did they occur?

Three deposits from explosive eruptions at the summit of Mauna Loa are located west, northwest and east of Moku‘aweoweo, the volcano’s summit caldera. In map view, these deposits are fan-shaped. Along the ‘Ainapo Trail, 2.8 to 3.5 km (1.7 to 2.2 mi) southeast of the caldera, several kipuka expose a fourth distinct explosive deposit.

Volcano Watch: Kilauea Volcano’s summit eruption is now a decade old

A little more than 10 years ago, conditions around Kilauea Volcano’s summit were much different than today. The caldera floor was open to the public, and the air above it was normally clear.
