Time-lapse of Halemaumau Crater Overlook Vent

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

A lava lake within the Halema`uma`u Overlook vent resulted in night-time glow that was visible from the Jaggar Museum overlook and by HVO’s Webcam during the past week. The lake level was fairly steady during the first half of the week at about 60 m (200 ft) below the floor of Halema`uma`u Crater. The lake began to drop slightly late on Wednesday, however, with the onset of a deflation-inflation (DI) cycle.

On Kilauea’s east rift zone, surface lava flows on the coastal plain have been slowly diminishing over the past week, their front more than 1 km (0.6 miles) from the ocean. There was no active ocean entry. Surface flows high on the pali, however, were more prominent and easily visible from the viewing area in Kalapana. Incandescence was visible from three degassing vents within Pu`u `O`o, including the pit on the northeastern side of the crater floor which has held a small lava pond. The lava pond was too low to be directly visible via webcam.

No earthquakes were reported felt under the island of Hawai`i in the past week.
