Time-lapse images of Mount St. Helens dome growth
(duration 1:26 minutes) – The rapid onset of unrest at Mount St. Helens on
September 23, 2004
initiated an uninterrupted lava
-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
(duration 0:20 minutes) – Time-lapse changes in the
and Crater Glacier
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
