June 19: Magnificent Desolation

Six weeks in, this eruption can still take one’s breath away.

USGS: During the helicopter overflight on June 18, crews captured this image of the growing Halema‘uma‘u crater viewed to the southeast. With HVO and Jagger Museum sitting on the caldera rim (right side, middle where the road bends to the left) it is easier to comprehend the scale of subsidence at the summit. The estimated total volume loss is about 260 million cubic meters as of June 15th. (Full-sized)

USGS: “Fissure 8 vigor increased overnight June 18-19 with lava fountains reaching up to 60 m (200 ft). Spatter built up the cone to the east and into the channel. In this photograph, spatter lands on the east cone and flows downward.” (Full-sized)
Today’s Eruption Summary

Today’s summit explosion came early, 5:05am HST, with a weak ash/gas plume that reached 5,000 feet above sea level (Kilauea is ~4,000). Every one of these explosions means more downdropping and subsidence, resulting in the colossal changes we’re seeing to Halema’uma’u.

In the Lower East Rift Zone, Fissure 8 climbed back up to 200 foot fountains last night, beefing up the sides of its cone with spatter (but not adding much more height).  This morning the river was full to the top of its levees with a few minor breakouts.

Some of these overflows made it past the edge of earlier flows. One went north up Pohoiki Road a short distance before stalling, while another crept northwest along Luana Street. Fissure 6, 15, 16 are “oozing” lava and steaming. Near the ocean, the channel has forked to create two ocean entries, but the only place where it’s still covering more land is a creeping southwest edge of the lava flow in the Vacationland area.
