Kīlauea fissure 8 lava channel transports "lava boats"

Geologists captured this time-lapse video of the perched lava channel issuing from fissure 8 on Kīlauea's lower East Rift Zone.

Rafts of accreted lava move down stream and look like boats moving down a river. These are termed lava balls or lava boats and form when portions of the fissure 8 cone or levees break away and are rafted down stream. As they move along

September 28, 2017

Thirty-seven years after the May 18, 1980, eruption of Mount St. Helens, Washington, scientists, engineers, land managers, and Federal, State, and County officials are still grappling with a challenge created by the eruption—how to prevent potentially massive downstream flooding by the release of water from Spirit Lake, located at the base of the volcano.
