Time-lapse movie of Halemaumau 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 produced night-time glow that was visible from the Jaggar Museum overlook and by HVO’s Webcam during the past week. The lava lake level rose to a new high stand, about 50 m (165 ft) below the floor of Halema`uma`u Crater, during a prolonged period of summit inflation that ended on October 9. As of this writing (October 11), the lava lake remains high, but the level could begin to fluctuate if back-to-back deflation-inflation events resume.
On Kilauea’s east rift zone, surface lava flows continued to accumulate at the base of the Pulama pali within the abandoned Royal Gardens subdivision. One branch extended seaward across the coastal plain, reaching 1.7 km (about 1 mile) from the shoreline on October 10, but was moving slowly. Within the Pu`u `O`o crater, the lava pond in the northeastern pit continued to circulate and was visible in the Webcam over the past week.
No earthquakes were reported felt in the last week below the island of Hawai`i.
