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 level rose and fell slightly due to a string of deflation-inflation cycles (DI events) at the summit.
On Kilauea’s east rift zone, surface lava flows reached the base of the Pulama pali, traveling through the abandoned Royal Gardens subdivision en route. 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 in response to the DI events.
One earthquake was reported felt across the Island of Hawai`i during the past week. On Monday, October 1 at 3:23 a.m., HST, a magnitude-3.0 earthquake occurred 1 km (1 mi) west of Ho`okena at a depth of 12.5 km (8 mi).

Advancing surface flows reached the base of the Pulama pali over the past few days, burning through one of the few remaining forested kipuka in the abandoned Royal Gardens subdivision. The white line marks the outline of the active flows. Photography by Tim Orr courtesy of USGS/HVO

Time-lapse movie of Pu‘u ‘O‘o Crater
Map showing the extent of lava flows erupted during Kilauea’s ongoing east rift zone eruption and labeled with the years in which they were active. Episodes 1-48b (1983-1986) are shown in gray; episodes 48c-€“49 (1986-1992) are pale yellow; episodes 50-€“53 and 55 (1992-€“2007) are tan; episode 54 (1997) is yellow; episode 58 (2007-€“2011) is pale orange; the episode 59 Kamoamoa eruption (March 2011) is at left in light reddish orange; and the episode 60 Pu‘u ‘O‘o overflows and flank breakout (March-August 2011) are orange. The currently active Peace Day flow (episode 61) is shown as the two shades of red—light red is the extent of the flow from September 21, 2011, to September 25, 2012, and bright red marks the mapped flow expansion from September 25 to October 4. There have been flow margin changes upslope, in the upper part of Royal Gardens, that are not yet mapped and not shown on this map. The active lava tube is delineated by the yellow line within the active flow field. An incipient tube extends downslope to feed the currently active flows, but it has not been mapped. The contour interval on Pu‘u ‘O‘o is 5 m.
