Here’s a film made soon after the quake:

The Retronaut site also has early color photos and films on other subjects.
Thanks. At 4:26 in the film, it’s the same street with the clock tower straight ahead.
Of course, everyone should remember that the bulk of the damage done in the SF earthquake and fire was done by the fire. Most of those were set by the Army (I think) as backfires to try to exstinguish the one fire started by the quake.
