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.

During this morning's overflight, the ocean entry laze plume was being blown offshore, allowing this fairly clear view (looking northeast) of the Pohoiki boat ramp at Isaac Hale Beach Park. Incandescent (glowing red) spots of lava can be seen within the flow field beyond the boat ramp. HVO geologists also observed a few oozes of lava on or near the western flow margin, but all appeared weak as of 6:00 a.m. HST.
