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.

A pair of video cameras overlook the coast along a beach on Whidbey Island, Island County at the northern boundary of Puget Sound in western Washington. View looks west out into the Strait of Juan de Fuca.

A nodal seismometer can be easily deployed for a month in a closely spaced array of tens of instruments. Arrays have been installed at Yellowstone National Park to map subsurface of geyser basins.

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.

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.

This thermal map shows the fissure system and lava flows as of 12:30 pm on Monday, June 4 The flow from Fissure 8 remains active, with the flow front entering the ocean in Kapoho Bay over the past day. The black and white area is the extent of the thermal map.

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.
