Time-lapse movie of Halemaumau Overlook Vent

The breakout from the upper flow field that began earlier this month is still active, with flows currently moving through the upper portion of the mostly-buried Royal Gardens subdivision. On the left is a conventional photograph, and on the right is a view with a thermal camera covering a similar area. The bright white and yellow areas mark the area of active flows in the thermal image. Photos courtesy of USGS/HVO

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 and several brief gas-driven rise-fall cycles.

On Kilauea’s east rift zone, surface lava flows remain active high on the pali, within the upper part of the abandoned Royal Gardens subdivision, about 7.5 km (4.7 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 in response to the DI events.

There were no earthquakes reported felt on the Island of Hawai`i in the past week.

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 48-€“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 (Mar-€“August 2011) are orange. The currently active Peace Day flow field (episode 61) is shown as light red, as mapped on August 8. The margins of the Peace Day flow field have changed very little since August 8. The thick red line shows the front of the currently active flows, which are in the upper portion of Royal Gardens subdivision and within the existing margins of the Peace Day flow field. The active lava tube is delineated by the yellow line within the active flow field. The contour interval on Pu‘u ‘O‘o is 5 m.

The lava pond in the northeast portion of Pu‘u ‘O‘o crater remains active, with persistent spattering at the pond margins and a slowly migrating lava surface. A time-lapse camera mounted on a tripod on the rim (left edge of photo) provides a sense of scale. Photo courtesy of USGS/HVO

A small skylight has been open for several weeks on the upper tube system, just southeast of Pu‘u ‘O‘o, providing a view of the lava stream within the lava tube. The lava rushing through the tube here is supplying the active surface flows shown in the image above this one. Photo courtesy of USGS/HVO
