Lava appears from under crust and drops into depression
Lava appears from under crust and drops into depression at front of advancing breakout. Width of blob of lava that appears is about 30 cm.
Lava emerges from under crust
Lava emerges from under crust along side of breakout on steep slope. Listen to creaking sounds, about halfway through video, as crust flexes and breaks. See still taken at 0610:15 today.

Lava flow
This clip lasts 30 seconds and so is a large file, but it shows such notable dynamics at flow front that it might be worth it to some of you patient ones. The active stream is 50-75 cm wide. Note, early on, how sliding crust plows into lava.

Lava cascade
Same cascade as in first clip, but viewed more from side to see lava falling down cliff and spreading across surface of lava delta. Similar view to still image taken at 0548 today.

Lava issues from breached tube
Lava issues from breached tube and quickly disappears over old sea cliff. Note that center of stream stands above margins. See still taken at 0545 today.

Surging cascade on steep cliff face
Surging cascade on steep cliff face. Note that surges override part of cascade next to cliff, which is slowed by friction with the cliff.

Lava in channeled breakout
Lava in channeled breakout from nearby tumulus flowing rapidly down steep slope before spreading out on flat ground. Same channel as shown in last two stills for today. Width of channel, about 2 m.

Two strands of flowing lava come together
Two strands of flowing lava come together to form single cascade on upper part of old sea cliff at Highcastle. Still taken at 0546 shows same scene.
