lava has broken from beneath crust
Detailed Description
A minute or two after lava has broken from beneath crust and started to cascade down sea cliff at Highcastle. Crust at very top of image is point of breakout at top of cliff. Lava is gushing out, not simply oozing. Its volume is small, however, so only a weak cascade ultimately develops. Width of flowing lava, about 1.5 meters.
