Volcano Watch - What we've learned from Kīlauea's 2018 lower East Rift Zone eruption

May 3, 2019, marks the one-year anniversary of the start of Kīlauea Volcano's 2018 lower East Rift Zone eruption. Over the past year, USGS Hawaiian Volcano Observatory (HVO) geologists and collaborators have been closely studying the vast amount of data collected during the summer eruption. Now is a good time to explore what's been learned, and what's still unfolding.

Volcano Watch - What caused—or did not cause—the 2018 Kīlauea eruption?

When a major geologic event occurs, scientists who study such events and the people who are directly or indirectly impacted by it seek to understand its cause. Often, a first step toward that understanding is to rule out what did not cause the event.

Volcano Watch - Eruption pause provides an opportunity to probe volcanic pollution

The end of Kīlauea's 2018 eruption this past September was accompanied by an enormous decrease in the amount of sulfur dioxide gas (SO2) emitted from the volcano. This has led to beautifully clear skies gracing the Island of Hawai‘i, particularly noticeable on the west side, where the volcanic pollution known as vog chronically collected in past years.

Volcano Watch - New outcrops make good geology

A good field geologist is an opportunist. Never content with what outcrops are available, she jumps at the chance to see another one, hoping that it will provide a better understanding to some question about what happened in the past.
