This animated GIF shows a sequence of radar amplitude images that were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system. The images illustrate changes to the caldera area of Kīlauea Volcano that occurred between May 5 and June 2 at 6:00 p.m. HST.

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.

Map as of 11:00 a.m. HST, June 3, 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.

Northern edge of the fissure 8 flow front on the night of June 1, as it approached the intersection of Highways 132 and 137, known as "Four Corners."

USGS scientists on HVO's overflight this morning (June 2) captured this image of the fissure 8 flow front as it advanced west along Highway 132. Around the time of this photo, 7:15 a.m.

Overnight (June 1-2), fissure 8 lava fountains decreased to heights of about 50 m (164 feet). The moon can be seen in the upper left.

As fissure 8 lava flowed into Green Lake, the lake water boiled away, sending a white plumehigh into the sky—visible from afar between around 11:30 a.m. and 1:30 p.m. HST.

Viewed from the intersection of Nohea and Leilani Streets at 10:15AM HST on June 1, the Fissure 8 lava fountain (to the right) appears to have decreased in height from previous sustained heights of 260 feet.

Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park to collect visual information on this changing eruption site.
