CWU's Nick Zentner from his
CWU's Nick Zentner from his home in Ellensburg, Washington on Sunday, June 7, 2020 during the global coronavirus pandemic. California's San Andreas Fault, Carrizo Plain, 1906 San Francisco Earthquake, clockwise rotation, Tanya Atwater, Chris Goldfinger, Baja-BC, etc.
00:00 Waiting for start time + mailtime
14:34 Intro to San Andreas Fault
16:00 Outline walkthrough
17:00 Basics of the San Andreas Fault (as distinct from Cascadia)
21:40 Visual explanation of San Andreas Earthquakes
24:30 Nuance of why quakes happen in sections, not all at once
25:37 Explanation of 1906 SF earthquake
27:54 Fault history observations by shifted natural linear features (e.g. streams) in the Carrizo Plain
35:22 Determining the recurrence interval (average years between events)
37:00 Variability in types of movement on the fault, connecting San Andreas to the clockwise rotation of PNW (Pacific Northwest)
40:20 A new thought to consider: Why do we have 50My of clockwise rotation evidence if there is NOT 50My of San Andreas movement?
41:00 San Andreas fault born ~20Mya, future will be that all of western coast has San Andreas fault (including PNW)
42:07 Baja British Columbia (a large portion of today's Baja California is now in British Columbia)
42:58 Why San Andreas is a big deal in Geology : Bedrock map of the Palo Alto quadrangle in the 1960s, pre-plate tectonics!
47:36 Setting up the cozy fort :)
49:30 History of Thomas Diblee
51:22 Drone footage of San Andreas fault in the Carrizo Plains
53:20 Story of the post - 1906 San Francisco earthquake
1:05:00 Crazy Pre-1906 and Post-1906 SF earthquake footage
1:08:10 Seismograph live stream on YouTube
1:09:30 Point Reyes geology map showing 300mi of movement
1:10:40 Fault movement animation
1:13:22 What happens with the Gulf of California? & shows how nuanced SA is
1:17:20 Q&A
