Time-lapse images of Mount St. Helens dome growth 2004-2008 (duration 1:26 minutes) – The rapid onset of unrest at Mount St. Helens on September 23, 2004 initiated an uninterrupted lava-dome-building eruption that continued until 2008. As shown in the video, recorded from Sugar Bowl on the edge of the Mount St. Helens' crater, an initial succession of lava spines, two recumbent and one steeply sloping, grew to nearly 500 m (1640 ft) in length before disintegrating into mounds of rubble. The trajectory of lava extrusion was affected by the geometry of the crater, particularly the proximity of the vent to the south crater wall, and by the growing volume of erupted material.

Time-series of dome and glacier growth at Mount St. Helens, Washington, 2004-2012

Time-series of dome and glacier growth at Mount St. Helens, Washington, 2004-2012 (duration 0:20 minutes) – Time-lapse changes in the lava dome and Crater Glacier from 2004- 2012. Sequence created from 1:12,000 scale vertical aerial photographs combined with ground control points from GPS measurement locations. Software was used to collect a 3-D point cloud and combined to make a digital elevation model. Information regarding volume and rates of growth of the lava dome and glacier are extracted from DEMs to monitor surface changes in the crater.
