A third lava flow from Hawaii's erupting Kilauea volcano streamed into the ocean on Thursday as US Marines Corps helicopters stood by to evacuate a Big Island community should molten rock or huge cracks block its final escape route.
Six huge fissures sent rivers of molten rock through a blackened, volcanic wilderness that was once jungle, farmland and rural homes.
Kilauea, one of the world's most active volcanoes, entered the fourth week of what may be an unprecedented, simultaneous eruption at its summit crater and along a six-mile string of fissures 25 miles down its east flank.
At least 50 rural homes and other structures have been destroyed by lava from the fissures. One person was seriously injured after being hit by a flying piece of lava.
