Continuation and further development of rapidly moving and changing breakout in Highcastle lobe. Still taken today at 0603 is of this breakout. Width of view, about 2.5 m.

Spreading and advancing breakout, the same as that shown in 0545 still image for today. Width of view, about 2 m.

Closer view of spreading and advancing breakout shown above. Width of view, about 0.6 m.

Two converging toes, the same as those shown in last two still images for today. Width of view, about 1.5 m.

Lava moving rapidly at front of breakout 880 m north of coconut grove. Width of view, about 1.5 m.

Lava at front of breakout moves into and burns dead shrubbery. Width of view, about 2 m.

Lava moving along east edge of breakout near ahu. Width of view, about 1 m.

Lava moves rapidly from under crust of inflating flow and finally disappears under overhang. Length of flowing toe, about 1 m.

Continued movement of lava across rope barrier. Muffled sounds of a long-lasting, migrating methane explosion can be heard about two-thirds of the way through the clip, followed by a "Wow."

Lava breaks out of inflated toe and moves down moderate slope with rolling motion, top faster than bottom. See still images for this day; sagging rope gives scale.

Broad toe of lava moves across rope that formed barrier for access to Wilipe`a lava delta.

Lava moving down rather steep slope and burning bush at snout of stream. Width of burning bush, about 1 m.

Toe of lava moving fairly rapidly down moderate slope along edge of Kohola flow. Note that lava moves more rapidly at top than at base of toe, in contrast to lava in video for March 1, which was moving across nearly flat ground. Note also developing wrinkles in moving crust.

Details of flow advance shown in 25-second clip. Lava oozes outward from base of flow, picks up loose flakes of crust (1-3 cm across) on ground surface, and lifts them up as flow thickens. This is how material once on ground surface gets onto top of flow.

Part of broad cascade and falls that suddenly gushed from under crust at top of sea cliff. Turn down your sound; lots of wind noise.

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.

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 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.

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.
