In July 2021, YouTube set all unlisted videos uploaded before 2017 to private (unless the channel owner had opted out). In the weeks leading up to this change, Archive Team archived many pre-2017 unlisted YouTube videos. If this video was uploaded before 2017 and has gone private, there is a chance that a 360p archived version can be viewed on archive.org via the site's Wayback Machine as follows: 1. Enter the YouTube URL in the Wayback Machine form or click on the following link: https://web.archive.org/web/20210000000000*/https://www.youtube.com/watch?v=rcFEg4mHAhY 2. Right-click on a blue entry in July in the calendar. 3. Click 'Copy link address'. 4. Paste the copied link address into your web browser's address bar and press enter.
Description: This is a visualization of the shaking produced by a magnitude 7.7 earthquake beginning at the southernmost end of the San Andreas fault in southern California. The animation here is 11 seconds, however the actual earthquake shaking shown would last about 4 minutes. The dashed line is the segment of the fault where one side will move up to 20 feet relative to the other side. The colors represent the intensity of shaking as the waves travel away from the fault. Note how shaking continues in the Los Angeles area for much longer than elsewhere. This is because of the deep layers of sediment that have filled in the "L.A. Basin" and other areas, that amplify the shaking. The video was made at the San Diego Supercomputer Center as part of a Southern California Earthquake Center project called TeraShake (http://www.scec.org/terashake).
