When I started FYFD, volcano footage was far rarer. These days the affordability and durability of drones and action cameras — along with the relative accessibility of eruptions in places like Iceland and Hawaii — means we get to see volcanic flows in glorious high definition. This footage comes from the recent Icelandic eruption on the Reykjanes peninsula. Lava fountains line the four-kilometer lava vent seen here, and flows from the vent spread into a delta-like fan in the field below. I never get tired of staring at molten rock that flows like water.
