Events at the summit of Kīlauea over the past few weeks have dramatically reshaped Halema‘uma‘u, shown here in this aerial view, which looks west across the crater. The obvious flat surface (photo center) is the former Halema‘uma‘u crater floor, which has subsided at least 100 m (about 300 ft) during the past couple weeks.

Fissure 8 (fountain visible in distance) feeds lava into an active braided channel that flows about 8 miles (north, then east) to the ocean entry in Kapoho Bay. USGS image taken June 12, 2018, around 6:50 a.m. HST.

This 'warped-curb' crack, the largest in the parking area for the former Halema‘uma‘u overlook (closed since 2008), is one of many that have sliced the parking area into slices. Ballistics (blocks of solid rock) strewn across the area are visible in the foreground.

Kīlauea LERZ lava flows and fissures, June 11, 3:00 p.m.
Kīlauea LERZ lava flows and fissures, June 11, 3:00 p.m.Map as of 3:00 p.m. HST, June 11, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

This thermal map shows the fissure system and lava flows as of 6:45 am on Sunday, June 10. The flow from Fissure 8 remains active, with the flow entering the ocean at Kapoho. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas.

Overflows of the upper fissure 8 lava channel this morning sent sma...Overflows of the upper fissure 8 lava channel this morning sent small flows of lava down the levee walls. These overflows did not extend far from the channel, so they posed no immediate threat to nearby areas. Channel overflows, like the ones shown here, add layers of lava to the channel levees, increasing their height and thickness.

Another explosion occurred at Halema‘uma‘u at 12:51 a.m. HST today, releasing energy equivalent to a magnitude-5.3 earthquake. Following the explosion, summit activity consisted mostly of passive degassing at Halema‘uma‘u, similar to what is shown in this image taken mid-morning.
