Three years after the cataclysmic eruption of Mount St. Helens on May 18, 1980, the U.S. Geological Survey scientists continue to monitor the volcano and its actively growing lava dome. USGS observers are shown surveying the shape of the dome from inside the crater blasted out by the 1980 eruption. Bright orange targets are placed high on the dome and are surveyed from stations established on the crater floor, like this one 200 yards north of the dome. By monitoring the inflation or swelling of the lava dome as magma moves up into it, geologists can predict eruptions up to three weeks in advance. Between eruptions, the dome inflates less...
