Today’s Eruption Summary

Sadly, yesterday afternoon was the end of Kua O Ka La Charter School and Ahalanui Warm Ponds. The flow that diverted west of Kapoho Crater created a channelized a’a flow all the way to the ocean. There is now a strong ocean entry at what used to be Ahalanui Beach Park. There are still multiple “ooze-outs” along the northern lava flow front spanning former Kapoho Bay— it’s now 6 km, 3.7 miles across— “despite no visible surface connection to the fissure 8 channel.”

The level of Fissure 8’s lava river was low above Pohoiki Rd in the hours before the summit collapse. USGSVolcanoes posted at 7:17pm today that they observed an increase in Fissure 8 activity following the 2:42pm summit collapse (mag 5.3, here’s video), raising its level again. But there were no overflows, apart from some “small channel breaches south of the ocean entry.”

Speaking of the ocean entry, Bruce Omori of @HotSeatHawaii captured a startling offshore laze/steam/lava explosion just offshore:

USGS field teams reported “no visible activity” at Fissure 22 or any other fissures besides 8.

Today, USGS also posted a 3-month timelapse of Halema’uma’u from the HVO panorama cam, April 14-July 11:

This is another busy news day.
