Map as of 2:00 p.m. HST, June 4, 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.

Video from helicopter overflight of Kīlauea Volcano's lower East Rift Zone on June 4, 2018, shows lava from fissure 8 entering the ocean at Kapoho Bay. View to the north.

This thermal map shows the fissure system and lava flows as of 12:30 pm on Sunday, June 3. The flow from Fissure 8 continues to advance and had a wide flow front advancing towards the ocean in Kapoho. The black and white area is the extent of the thermal map.

What a difference four days makes! These thermal images of fissure 8 fountains erupting on Kīlauea's lower East Rift Zone show a few things: 1) The lava fountains have gained height—with the tallest one growing from 150 ft to over 250 ft. 2) A pu‘u (cone) has built up downwind. 3) The amount of material wafting downwind is greater.

Overflight photo at 7AM HST from offshore looking up the flowfront. Nearly all of the front was active and advancing/spreading.

Summit plume at 8:40AM HST on June 3. A slight mist in the air softens the look of the plume, which is predominantly white steam with very minor amounts of ash.

Photo from 7AM helicopter overflight, hovering offshore and looking up the flowfront. Nearly all of the front was active and advancing; advance rates were estimated at an average of 250 feet/hour (76 m/hr), and as of 7AM the flow was 500 yards (457 m) from the ocean.

This thermal map shows the fissure system and lava flows as of 5:30 pm on Friday, June 1. The flow from Fissure 8 continues to advance in a northeast direction and the front was roughly 9.5 km (5.9 miles) from the vent at Fissure 8. The black and white area is the extent of the thermal map.

This thermal map shows the fissure system and lava flows as of 6:45 am on Saturday, June 2. The flow from Fissure 8 continues to advance in a northeast direction and the front was roughly 10.1 km (6.3 miles) from the vent at Fissure 8. The black and white area is the extent of the thermal map.
