Cascade and lava falls on west edge of Kohola ocean entry
Cascade and lava falls on west edge of Kohola ocean entry, falling over sea cliff about 8 m high. Turn down your sound; lots of wind noise.
Lava Cascade
Base of lava cascade and construction of mound on beach below sea cliff. Turn down your sound; lots of wind noise.

Front of flow advancing
Front of flow advancing rather quickly across grassland about 70 m from Chain of Craters Road. Grass ignites a short distance ahead of the lava, owing to the intense radiant heat. Width of scene, about 4 m.

Video of lava flows
Same flow as in upper video, but a little farther upstream. Grass burns along the side of the stream. Width of view, 4-5 m.

Lava runs from under crust along edge of inflating flow
Lava runs from under crust along edge of inflating flow. Flakes of crust, heated by the emerging lava, spall off and fall onto surface of lava. Width of view, about 75 cm.

Lava tear
Tear begins to develop in crust on stage-left side of flow. Lava eventually pours from tear. Stream is 0.75-1 m wide.

Rushing toe of lava
Rushing toe of lava that has just broken out from front of one active lobe of flow on coastal flat seaward of Paliuli. Toe is about 50 cm wide. Note how crust is "scrunched" at bottom of minicascade, resulting in wrinkles. Other videos on this day show breakouts in same area. In all videos, wind noise may be bothersome.

Slow moving lava
Lava slowly rafts plate of crust downstream. Width of plate of crust, about 1 m.

Small gush of lava
Small gush is on crest of small divide and starts flowing down right side as well as left. Stream is about 1 m wide.

Two streams break from under inflating flow
Two streams break from under inflating flow. Note how crust forms on closer stream and becomes wrinkled where lava runs into barrier. Each stream is about 3 m long.

Wrinkling of thin crust
Video shows wrinkling of thin crust at bottom of gentle slope. Note the concave-upstream shape of the wrinkles. Stream is about 1 m wide.

Rapidly flowing single toe of lava
Rapidly flowing single toe of lava at front of flow 440 m seaward of Paliuli. Other videos on this day focus on similar toes. Sound was turned off during the imaging. For scale, flowing lava in all clips is 1-3 m wide.

Channeled cascade on Paliuli
Channeled cascade on Paliuli. Other videos on this day focus on front of this cascade. Wind noise in this and other clips is obvious, but listen for sounds of pieces of crust scraping against one another or across ground. For scale, flow front in all clips is 1-1.5 m high.
