Lava breaks out of inflated toe

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.

Lava moving rapidly

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.

Lava flow advancing

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. This is a common mode of advance of lava on nearly flat slope. Note: This is a large file because of its
