The Hawaiian Volcano Observatory reported Tuesday of a recent overflow at Kilauea Volcano’s summit lava lake.
The lava overflowed the vent rim between 1 and 2 p.m., and again around 6:30 p.m. on Saturday, Oct 15.
In the image above, small spill-overs (shiny black lava) on the east (far left) and west (right) sides of the vent rim can be seen.
In recent weeks, the lava lake level has been rising and falling in concert with summit inflation and deflation, with the lake surface often in view of Hawaii Volcanoes National Park overlooks.
On September 22, the lake level rose to within 33 feet of the vent rim, the highest level reached since the previous lake overflow in April-May 2015. Since then, the lake level has risen and fallen multiple times.
A switch to summit inflation on October 13 led to Saturday’s brief overflow, which was soon followed by a return to summit deflation and a drop in the lake level.
As of Tuesday morning, the summit lava lake level was 56 feet below the vent rim.
