Attempt to Drain Dangerous Volcano Crater
A dozen tribesmen with picks and shovels climbed the Mount Pinatubo volcano last week on the dangerous mission to drain the crater lake that threatens their villages with massive floods if the volcano explodes, as it is threatening to do.
Their aim is to carve a notch in the volcano?s crater, to slowly release water from the rising lake, by chopping 16 feet off the lowest point of Pinatubo?s summit. When the notch is completed, geologists predict another 16 feet of already-weakened wall will give way, draining about 530 million cubic feet of water in five hours. The lake contains an estimated 7 trillion cubic feet of water.
