The ages of the past major San Andreas “big ones” can be found in the Uniform California Earthquake Rupture Forecast, Version 3 ( UCERF3 ), Appendix G — Paleoseismic Sites Recurrence Database .
Below are screensnips of the dates from the paper beside Google Map images showing where the dating samples were collected. The images begin at the southern most tip of the San Andreas and move north to where the fault (more-or-less) meets the Cascadia Subduction Zone.
Event dates taken from Noyo Canyon were used to compare event timing with historical major earthquakes on the Cascadia Subduction Zone. Three worthwhile sources from the recently released research on the CSZ-NSAF connection are listed below. Those highlighted in green were likely a “one-two punch” near simultaneous.
- Media article: Big U.S. West Coast earthquakes could come as a one-two punch | Science | AAAS
- Scientific article: Unravelling the dance of earthquakes: Evidence of partial synchronization of the northern San Andreas fault and Cascadia megathrust
- Plain-language blog post: New paper, direct evidence of triggering of the northern San Andreas after Cascadia great earthquakes.
“If Cascadia went off, I would take that pretty seriously [as] a very clear advance warning for the northern San Andreas,” – Chris Goldfinger
