Spattering is common in the summit lava lake in Halema‘uma‘u Crater. This afternoon, spattering was active at a site along the east lake margin. Spatter deposits have built a small ledge extending out from the crater walls (lower right of photo), onto which fluid spatter often falls.

The June 26 breakout remains active at the flow front, which can be distinguished by the light silver color at the bottom-center of the photo.

A zoomed in view of the Kamokuna lava delta reveals several crack systems parallel to the sea cliff which suggests instability of the delta. Over the past few weeks, flows on the delta have built up the surface near the base of the cliff creating a slope seaward.

This image shows a comparison of a normal photograph (left) with a thermal image (right) of the lava delta. The cracks spanning the delta, and the warm water plumes extending out from the entry point, are evident in the thermal image.

This video clip gives a view of the ocean entry and the cracks on the lava delta.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of June 21 is shown in pink, while widening and advancement of the active flow as of July 10 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray. The yellow line is the trace of the active lava tube.

USGS scientists continue to monitor the slide by collecting imagery every couple of weeks, weather permitting. Pilot Bob Van Wagenen, contracted through the Department of the Interior’s Office of Aviation Services, takes air photos for Jon Warrick’s Big Sur Landslide team, flying out of the Watsonville Municipal Airport in a Cessna 182R.

This video shows timelapse images of active pāhoehoe toes near the base of the pali.

During the March 2011 Kamoamoa fissure eruption on Kīlauea Volcano's East Rift Zone, spatter from this line of lava fountains just west of Pu‘u ‘Ō‘ō reached heights of 40 m (130 ft).

A breakout that started June 26 on the upper pali is now advancing across the coastal plain. The flow front has advanced approximately 500 m (0.3 miles) from the base of the pali, and was about 2.7 km (1.7 miles) from the emergency road this morning.

A closer look at the pāhoehoe flow on the coastal plain with pali in background. As the flow spread across the ground, its surface cooled and developed a hardened crust.

This spectacular lava fountain, erupting from Pu‘u ‘Ō‘ō on June 30, 1984, lasted just over 7 hours and reached a height of 318 m (1043 ft). It was one of 44 high lava fountains erupted during the first 3.5 years of Kīlauea Volcano's ongoing East Rift Zone eruption, which began in January 1983.

On the evening of June 30, 2008, littoral explosions at Kīlauea Volcano's Waikupanaha ocean entry created a fireworks-like display as incandescent fragments of lava flew through the air. When molten lava entered the sea, the water flashed to steam, triggering explosions that hurled spatter and other lava fragments up to heights of 50 m (164 ft).
