Pu`u `O`o vent, part of Kilauea Volcano, Big Island, Hawaii. This vent has been active on and off in the 22 years since 1983. For most of that time, the cone has repeatedly grown and collapsed; according to the United States Geological Survey, the crater is about 1,300 ft (400 m) long and 820 ft (250 m) wide. At times, the crater has been as deep as 690 ft (210 m) although recent lava flows have filled much of the crater. The Geological Survey also reports that in early 2005, this cone was releasing approximately 3,000 to 5,000 tons (roughly 3,000,000 to 5,000,000 kg) of sulfur dioxide each day. To generate this volume of gas release, geologists calculate that over a million cubic yards/meters of lava are erupting every day from this volcanic system.
