This is the Pu'u O'o crater on Kilauea where a fissure eruption started when the floor of the crater collapsed. The fissure is approximately 1,605 feet long. There were 150 small earth quakes recorded within Kilauea in the last 24 hours.
Along with the lava fountains 65 feet in the air, there is the danger of lethal sulphar dioxide gas around the eruption area. The best way to see the eruption is from someone else's photographs.
