NASA scientists took this visible and infrared (IR) digital image which shows renewed volcanic activity at Mount St Helens. The image shows an increase in the number of hot spots as well as a plume of smoke coming from the crater. Bright red in the crater indicates hot spots, and blue indicates snow and the plume. In 1980, Mount St Helens erupted, destroying over 270 square miles of forest in a few seconds, and sending a billowing cloud of ash and smoke 80,000 feet into the atmosphere.
