May 30: Pele Makes A Run For Four Corners

Today’s Eruption Summary

In fact, the current lava eruptions in Puna are as hot as Hawaii’s lava will ever get. “It can’t get hotter than where we are,” Stovall added. “We are pretty much tapping mantle temperatures right now.”

Fissure 8 is beauty & the beast. Since Saturday it’s been pumping out a huge volume of lava, creating pahoehoe and even a’a flows that occasionally surge up to ~600yards/hour. Yesterday its main flow headed NE, skirted the geothermal plant, crossed and followed Hwy 132 for a while, and then started downslope past Noni Farms towards Four Corners, threatening to cut off Kapoho and Lower Puna.

In the early morning hours, officials went door-to-door in the Kapoho area ordering emergency evacuations.  Newly-paved Beach Rd was pressed into service as a one-way evacuation route from Four Corners to Hawaiian Beaches. But it’s a race against time, as the lava is headed for that very road.

I saw no PGV news today, which is good. The summit produced yet more ash & earthquakes, one a pretty good thump (Mag 5.3 at 10:57am, no tsunami). Meanwhile, Fissure 18 is sending a channelized flow towards Hwy 137, just a little east of last week’s flows to the ocean:
