Breathtaking aerial videos of the Kilauea volcano erupting

posted by Jason Kottke   Jun 28, 2018

Mick Kalber is posting daily flyover videos of the eruption of the Kilauea volcano in Hawaii. This one, from June 23, is one of the better ones from the past week and features a frothing ocean of erupting lava and a speedily flowing river of molten rock.

The Volcano Goddess, Pele is continually erupting hot liquid rock into the channelized rivers leading to the Pacific Ocean. Most of the fountaining activity is still confined within the nearly 200-foot high spatter cone she has built around that eruptive vent. Her fiery fountains send 6-9 million cubic meters of lava downslope every day… a volume difficult to even wrap your mind around!

According to the USGS, the temperature of the lava when it erupts is around 2140 °F, which is pretty hot but not as hot as a kiln can get when firing some high-fire clays and porcelains. (thx, christopher)

Hawaiian mega-tsunamis with 1000 ft waves

Scientists have found evidence of mega-tsunamis hitting the Hawaiian islands that were more than 1000 feet high. The tsunamis are caused by landslides from collapsing volcanos but don’t occur very often (every 100,000 years).

There are at least 15 giant landslides that have slid off the Hawaiian Islands in the past 4 million years, with the most recent happening only 100,000 years ago, according to the U.S. Geological Survey. One block of rock that slid off Oahu is the size of Manhattan.

Judith lost her camera (and most of her pictures) on her trip to Hawaii, so she’s using other people’s photos from Flickr to produce a trip journal.
