A volcano in Hawai’i

A volcano in Hawai’i was home to a dramatic feature last month: a ‘firehose’ of molten lava that streamed from a hole in a sea cliff into the Pacific Ocean. The creation of the stream was widely reported, and according to the US Geological Survey, the cliff has now collapsed.

The massive section of the Kamokuna lava delta, located in Hawai’i’s Volcanoes National Park, initially collapsed into the ocean on New Year’s Eve. The section had been an ideal viewing platform for visitors hoping to look at the active Kilauea shield volcano and the lava that it spews out. According to the USGS, the collapse caused “solid and molten fragments of lava and super heated steam exploded skyward, creating tremendous hazard for anyone” who had ignored warning signs.

What remained was a beautiful stream of red, molten lava pouring out from the newly-formed cliff into the ocean, creating a massive plume of steam.

Geologists at the Hawaiian Volcano Observatory first spotted cracks on the cliff from aerial surveys on January 25th, and visited the site to take measurements and observed a foot-wide crack in the ground. They noted that the crack could likely “be a precursor to collapse of an unstable section of the sea cliff,” and continued to warn visitors away. In the following days, the crack grew two and a half feet, and geologists on the scene reported that they could hear and see the section of rock moving. “These signs indicate that the section of sea cliff around the ocean entry is highly unstable and could collapse at any time.”

When the geologists hiked back on February 2nd, the section of rock did just that: it collapsed into the sea before them without warning. (They were unharmed).

 

The latest collapse meant the end of the spectacular firehose stream, although there are indications that lava is still flowing into the sea

The images and video show the raw power of volcanic activity. It’s beautiful, but incredibly dangerous
