Kīlauea LERZ lava flows and fissures, June 19, 1:00 p.m.

Map as of 1:00 p.m. HST, June 19, 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.

Geology field crews on the ground near the Kīlauea's fissure 8 midday on June 19, 2018 observed a still-vigorous channelized lava flow being fed by lava fountains at the vent. Standing waves are visible within the channel. Cascades/rapids are visible near the base of the cone, which is an estimated 50 m (164 ft) high. The maximum flow velocity in the channel is 7.7 m/s (17

Fissure 8 cone, lava fountain, and channelized lava flow on the morning overflight - June 19 at about 6:10am HST. The lava channel is very full with many small overflows visible on the channel margins. Overflows are sluggish and move slowly downslope as they build up the levees.

A healthy coral reef at Buck Island, U.S. Virgin Island
April 20, 2017

In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.

The ash deposits on the southeastern part of the Island of Hawai‘i have fortuitously presented an agricultural opportunity in an otherwise rocky and hilly landscape. An underappreciated fact is that the explosive nature of our volcanoes provided this opportunity.
