Photographer heard cracking sound, glanced up, and saw top of tumulus sliding seaward (left). After wits were regained, this scene was shot. Lava was gushing from inside tumulus into water but was obscured from this vantage point. Collapsed top of tumulus is relatively smooth sloping area at left, with glow reflecting off inner wall of tumulus. Width of view, 8 m.
Setting for images in top row. Lava comes out of tumulus (high mound just left of source of lava) and flows down front of new western delta. Tumulus had several incandescent cracks a few minutes before it broke open; one can still be seen in this image.
New eastern delta of Banana flow, looking southwestward. Near end of delta is built on black sand. Small entries are taking place at left tip of delta, and other larger ones are in distance creating large steam plume.
Wider view of northeast end of delta. Lava falls in left image is just above leading edge of swash. Larger entry is at left, where lid on tube has been tipped seaward.
