Lars, thank you for posting this.

Hi, I found the data I wanted on the NOAA Tide Gage page. If you look at the graphs for Port of San Francisco you can see the signal of the tsunami in the difference between the predicted and actual sea level. The higher frequency signal begins when the tsunami was supposed to arrive and continues. It is still going on.

Time lapse begins at 8:35a, ends at 9:57a, almost an hour and a half long compiled from 323 photos, one taken every 15 seconds. The idea occurred to me after the first surge already passed so this does not document the entire event. The harbor master tied the caution tape to mark the high water line on the piling at 8:16a. Here are peak times: 8:41a high, 8:49a low, 8:59a high, 9:06a low, 9:18a high, 9:29a low, 9:41a high, 9:54a low.

The San Bruno police and the local volunteers did a very good job but overreacted being that the most significant danger on this basically hilly coast, people could evacuate to high ground in 5 minutes.........as it is, hundreds of panic "queens" immobilized the highway out of town and had to sit on the side of the road for hours almost at 1200 feet elevation.It was more comical than organized.I wish this area were as organized to have prevented city going bankrupt in HMB.

Can you give us timestamps for the photos?

@bruce122046 I tried to export the photos with the time, but couldn't figure out a way to do it. Summary of the high and lows is now posted above.. .
