Mount St. Helens: Instrumentation and Dome Growth, May-Sept 2006

Throughout the eruption, scientists installed monitoring stations to track volcanic activity, deployed temporary monitoring ""spiders"", monitored the temperature of lava spines and created time-lapse of dome growth. During the 3+ years of the eruption, lava piled up to form a new dome 460 m (1,500 ft) high. The 92 million cubic meters (121 million cubic yards, or 36,800 Olympic swimming pools) and is roughly equivalent to the volume of the 1980–86 lava dome. Together, the two domes have refilled about 7% of the Mount St. Helens crater created on May 18, 1980. 1.
