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.
