Another explosion occurred at Halema‘uma‘u at 12:51 a.m. HST today, releasing energy equivalent to a magnitude-5.3 earthquake.

Map as of 12:00 p.m. (noon) HST, June 10, 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.

Fissure 8 continues to erupt vigorously, with lava streaming through a channel that reaches the ocean at Kapoho Bay. The width of the active part of the lava channel varies along its length, but ranges from about 100 to 300 meters (yards) wide.

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.

A photogrammetry survey of Kīlauea's summit by the U.S. Department of Interior Unmanned Aircraft Systems' (UAS) Kīlauea response team show changes that have occurred at Halema‘uma‘u as of June 8. Cracks through the former overlook parking lot (bottom of image) wrap around the east margin of Halema‘uma‘u and extend to the north.

This thermal map shows the fissure system and lava flows as of 5:30 pm on Saturday, June 9. 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.

A closer view of the fissure 8 lava channel with the cinder quarry more clearly visible in the foreground (bottom of photo). During this morning's overflight, HVO geologists observed no new breakouts of lava near this quarry.

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.

USGS-HVO geophysicists installed additional continuous GPS stations around Halema‘uma‘u this morning. These stations will allow scientists to better monitor and measure the ongoing subsidence of Halema‘uma‘u and the adjacent caldera floor.

Fissure 8 and lava channel in the lower East Rift Zone of Kīlauea Volcano during this afternoon's overflight, with no apparent slowing in the eruption rate. The lava channel remained incandescent all the way around Kapoho Crater before entering the ocean.

An aerial view of the Kapoho ocean entry, as of 6:30 a.m. HST today, shows the extent of the lava delta, now about 200 acres in size, that has formed over the past six days (lava first entered the ocean on the night of June 3).

As of 6:30 a.m. HST today, fissure 8 continued to feed a vigorous channelized lava flowto the east of the vent.

Cracking and slumping of the Halema‘uma‘u crater walls are clearly evident in this aerial view captured during HVO's overflight of Kīlauea's summit this morning. Steam plumes have been rising from within the crater, as well as from cracks adjacent to the crater.

Map as of 10:00 a.m. HST, June 9, 2018. The fissure 8 flow has created a lava delta approximately 200 acres in size, filling Kapoho Bay and shallow reefs along the nearby coastline.
