Halemaumau Crater---The Earth Breathes

Look at that big hole, called a vent, in the earth's crust on the rim of Halemaumau Crater on the Big Island. It's spewing 1,000 tons of steam and sufuric acid and other gases every day. Yikes! I'm standing on the wall of the Jagger Museum at Volcano National Park. Sometimes the wind shifts and the gases drifts towards the park. They can be so toxic that the whole place gets closed down.
