On Friday, fast-moving lava crossed a road and isolated about 40 homes in a rural subdivision, forcing at least four people to be evacuated by county and National Guard helicopters.

The wide lava flow was "very active" Saturday morning and advancing at rates of up to 300 yards (274 meters) per hour, scientists from the Hawaiian Volcano Observatory said.
