I love these old films. They show slices of history in an engaging form.
Excerpt from Library of Congress website:
This film shows the aftermath of the San Francisco earthquake of April 18, 1906, and the devastation resulting from the subsequent three-day fire. The 8.3 magnitude earthquake struck at 5:12am and was centered along the San Andreas Fault, which slices through coastal California. Most of the cities of central California were badly damaged. San Francisco, with thousands of unreinforced brick buildings - and thousands more closely-spaced wooden Victorian dwellings - was poorly prepared for a major fire.
This film is hosted by the Library of Congress. To view go here Your best bet is to click on the mpeg file. If that link doesn't work try going to http://memory.loc.gov/cgi-bin/query/S?ammem/papr:@FIELD%28COLLID+sanfran%29 scroll down to number 17. Sorry about the broken links. I can't image what the Library of Congress is doing.
