New aerial video shows stunning transformation of Kilauea's summit

Here' new incredible aerial video at the summit of Kilauea!

PUNA, BIG ISLAND (HawaiiNewsNow) - Since early May, the crater floor at Kilauea's summit has collapsed a stunning 1,600 feet.

How tall is 1,600 feet? Taller than the Empire State building (by 350 feet) and the Eiffel Tower (by 540 feet)

That's according to the U.S. Geological Survey, which along with other federal agencies used drone flights to conduct new aerial surveys of the summit.

The footage shows a dramatically changed summit landscape. The total volume of Halemaumau Crater at the summit is now over 825 million cubic meters, enlarged by near daily explosive eruptions that have now gone quiet.

At the same time, eruptions in lower Puna sent rivers of lava flowing through neighborhoods, destroying whole communities — and more than 700 homes — and creating more than 850 acres of new land.

For weeks now, though, the eruptions have come to a standstill. (Scientists have stopped short of saying the event has come to an end.)

Last week, a drone flight showed there was no longer any incandescence within the fissure 8 cinder cone in Leilani Estates, which is 164 feet high.

Although there are minor amounts of gases rising from the north wall of the cinder cone, scientists say it is primarily steam.

Sulfur dioxide emissions from both the summit and lower east rift zone are also significantly reduced. Scientists say the combined rate is lower than any time since late 2007.

In mid-August the Hawaiian Volcano Observatory lowered the alert level for Kilauea from "warning" to watch."

"Although no signs of imminent hazardous activity are present at this time, residents of the region near recently active fissures should stay informed, heed Civil Defense warnings, and be prepared, if necessary, to self-evacuate," the observatory, said in a statement.
