The ebb and flow of volcanic activity at Kilauea saw an increase in lava activity this weekend, followed by a drop in lava levels Sunday night, the Hawaiian Volcano Observatory reports.
The lava lake at the summit started rising Saturday afternoon only to drop starting Sunday afternoon.
At Puu Oo crater, lava flows could be seen on the east and west edges of the crater floor, from a fissure on the southeast flank of Puu Oo and from a skylight on a tube where lava is flowing.
The increased activity followed inflation of the volcano, followed by a deflation episode as lava levels dropped.
Lava has advanced about 3.5 miles to the southeast since a Sept. 21 fissure eruption at Puu Oo. But scientists say the lava's advance has been slowed by the "highly variable" flows due to deflation/inflation events.
