|The Oso Landslide animation|
We remember the victims and honor them. Hopefully the missing people will be found, safe and sound.
The U.S. Geological Survey studies these sorts of things intensely. One of its units, the Cascades Volcano Observatory, was well situated to study the situation. It put together an animation, using a unique program developed for this purpose that has taken decades to refine, to show the progress of the landslide.
It may not be the most exciting or entertaining animation you will see, but it shows an important use of animation in the study of geological deformations.
You may have seen pictures of the result, with the road below Hazel Hill completely covered. Geologists estimate that the wall of earth and mud was moving at a speed of 60 miles per hour as it came down the hill. It is estimated that the destruction covered the mile from its origination to its conclusion in about a minute. Approximately 10 million cubic yards of earth was moved in that minute.
A local newscast discussed the animation to help us all make sense of it:
The raw animation itself is below:
