Kilauea activity update
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 level fluctuated slightly due to several deflation-inflation (DI) cycles at the summit and several brief gas-driven rise-fall cycles.
On Kilauea’s east rift zone, surface lava flows remain active above the pali, near the top of the abandoned Royal Gardens subdivision, about 5.5 km (3.4 miles) southeast of Pu`u `O`o. The lava pond in the northeastern pit in Pu`u `O`o crater was visible in the Webcam over the past week, with the level fluctuating slightly due to the deflation-inflation cycles. Small amounts of lava were also visible in the southern pit on the crater floor.
One felt earthquake was reported in the last week on the Island of Hawai`i. A magnitude-3.0 earthquake occurred at 4:23 a.m., HST, on Tuesday, September 11, 2012, and was located 5 km (3 mi) south of Volcano at a depth of 3 km (2 mi).
