Close Up of Cone Forming - Kīlauea Lower East Rift Zone

A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).

Kīlauea lower East Rift Zone

On September 4-7, the Unmanned Aircraft Systems team flew several missions documenting changes within fissure 8 on Kīlauea's lower East Rift Zone. On September 4, lava erupted on the crater floor within the vent, building a small cone on the floor and creating a flow that did not extend beyond the vent walls. On September 5, gas bursts briefly lifted the crust over a small

Kīlauea Lower East Rift Zone

This is, without a doubt, the most intellectually exciting time to be a volcanologist at the USGS Hawaiian Volcano Observatory. The current inactivity at Kīlauea has so many possible outcomes that it is a real challenge to figure out what might happen next. And intellectual challenges are stimulating and exciting.

The prolonged yet dramatic partial collapse of Kīlauea caldera this past summer was the first to be observed in detail and the largest measured by subsidence volume of more than a dozen summit collapses in the past 200 years. The earliest known collapses (1823, 1832, and 1840) were large in subsidence volume but the process was not recorded by witnesses.

The 2018 summit collapse and lower East Rift Zone eruption at Kīlauea Volcano were dramatic and, for many Island of Hawai‘i residents, tragic events. As with all eruptive crises, these events offered exceptional opportunities to learn more about how volcanoes work and to answer some "bigger picture" questions.
