HAWAII VOLCANOES NATIONAL PARK - As the June 26 breakout continues to advance across the coastal plain, USGS scientists map the activity.
(BIVN) – Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone, sending lava to the sea miles downhill.
Geologists from the USGS Hawaiian Volcano Observatory reported that the June 26 breakout on the episode 61g flow remains active at the flow front. “The flow has been slowly advancing along the eastern margin of the main episode 61g flow field, and this afternoon was approximately 1 km (0.6 miles) from the base of the pali and 2.2 km (1.4 miles) from the emergency access road,” the scientists reported.

This new map was published by the USGS and posted to the Hawaiian Volcano Observatory website on Monday.
(USGS map) 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.
Ariel photos gathered at the the lava ocean entry show what appears to be growing instability of the lava delta.
(USGS 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.
These flows do not pose any threat to nearby communities at this time, scientists say.
