Geologist Jerry Magloughlin made a lava video that’s a real labor of love. It describes the marvelous complexity of Hawaiian lava flows, combined with lots of cool footage and interesting facts. Plan on learning many new things.
Via Jerry:
A geologist describes the types of lava flows found on Hawaii, including pahoehoe and aa, shows what happens when wood is introduced into pahoehoe lava, and shows why lava deltas are dangerous and can disappear quickly. Animations, aerial footage, ground shots, time lapse.
