HONOLULU -

On Jan. 3, it will be 35 years since the eruption of Pu'u O'o on Kilauea Volcano's East Rift Zone and it's still going strong, according to the Hawaiian Volcano Observatory.

Volcano experts reflect on what happened at Pu'u O'o during 2017.

The  year started off with the collapse of the eastern Kamokuna lava delta formed by an ocean entry during the last five months of 2016.  About 25 acres collapsed into the ocean over a period of four hours leaving only 2.5 acres of the original delta.

By April, the Kamokuna delta had begun to reform growing out from the sea cliff.  But, in early May, this delta became unstable and collapsed.

By August, the Kamokuna delta was about 8-to-10 acres in size.  Between August and November, enough material was added to the lava delta to double its height above sea level.

In October, an apparent blockage with the lava tube caused many overflows on the sea cliff.  HVO scientists say lava breakouts from the lava tube occurred frequently in 2017.

The lava pond at Pu'u O'o was active all year round.

HVO is inviting the public for Volcano Awareness Month presentations in January. Details are posted on the HVO website (https://volcanoes.usgs.gov/hvo/). You can also email askHVO@usgs.gov or call 808-967-8844 for more information.
