South side of Halemaʻumaʻu at the summit of Kīlauea Volcano, showing a short section of Hawaiʻi Volcanoes National Park’s Crater Rim Drive (arrow) preserved on a block of the former caldera floor that has dropped down about 80 m (260 ft). Thinly bedded Kīlauea explosion deposits (E) from 16th-18th centuries are overlain by 19th and 20th century lava flows in the wall of Halemaʻumaʻu. USGS photo by D. Swanson.

Volcano Watch: Will this summer’s limited collapse of Kīlauea caldera eventually widen?

Putting together the evidence for such events is complicated, time-consuming, field-oriented research, but it paid dividends at Kīlauea by recognizing the large-scale cyclic behavior of the volcano during the past 2,500 years.

Volcano Watch: Voggy skies from days gone by – Reviewing Kīlauea Volcano’s gas release

Vog watchers may have noticed significant changes in air quality on the island since early May 2018, when Kīlauea’s extraordinary lower East Rift Zone (LERZ) eruption began. Revisiting how much SO2 has been released from Kīlauea over the past decades helps us understand the island’s current vog situation.

Kilauea Eruption: Volcano still fairly quiet, Civil Defense discontinues daily updates

The Hawaiian Volcano Observatory reports that activity on the lower east rift zone of Kilauea Volcano has diminished and remained quiet for over a week. The only surface activity is a small, crusted lava pond inside the fissure 8 cone, and a few areas along the coast where lava is entering the ocean. Sulfur dioxide […]
