Flowing Lava
Lava can move in two ways, wide flat lava flows, or through channels which squeeze the lava into a small area. The fastest lava flows move at about 6 mi/hr, an easy jog, but they average between 2/3 and 1/3 mi/hr.
Lava in channels can move very quickly. It can typically move up to 23 mi/hr (a sprinter's top speed), but have moved at up to 35mi/hr, faster than any person can run!
