A blackened section marks where snow from the last two eruptions melted, as a small dark bulge in front of the lava dome, center, malforms the dome, in the crater of Mount St. Helens, Sunday. A second long tremor early Sunday and an increase in volcanic gases strongly suggest magma is moving inside Mount St. Helens, researchers from the U.S. Geological Survey said. The mountain's alert was raised to Level 3, the highest possible, after a volcanic tremor was detected Saturday for the first time since before the mountain's 1980 eruption.
