Today’s Eruption Summary
The Lower East Rift Zone eruption continues as per usual. USGS reported during today’s morning overflight that “the channel was incandescent its entire length from vent to ocean entry.” There’s a main ocean entry a few hundred meters NE of the southern flow border with smaller pahoehoe flows on either side. The southern margin doesn’t seem to have advanced much from yesterday.
No other fissures are active, and I already covered yesterday’s 4:33 HST collapse event. I’m betting the next one will be after dark.
State Highways have put a speed limit of 25 on Highway 11 between Mile Marker 28 and 30 due to cracks in the road.
The USGS today released a new report for Civil Defense planning: “Fissure 8 Prognosis and Ongoing Hazards”.
“If the ongoing eruption maintains its current style of activity at a high eruption rate, then it may take months to a year or two to wind down.”
Here’s the July 19 thermal map of the LERZ posted this morning.
