Black’s Beach Cliff Collapse- I Was There!

Blacks Beach Cliff 2018 featured image

Guess what! I was there when the cliff collapsed at Black’s Beach! I was about a mile away, checking out the bean clams on La Jolla Shores Beach.  Would you believe I didn’t even realize what had happened at 1:29 p.m. until three days later? Yes, it is true, but I am here now and have photos to share. Viewing these incredible videos, let’s look at the January 20, 2023, Black’s Beach cliff collapse! I have also researched and included every past cliff collapse at Torrey Pines State Beach for fun. Finally, I look deeper into the cliffs’ geology and try to figure out a few clues on why the cliff collapsed.

I want to say right up front that I am not a geologist and am trying my hardest, so if I get anything wrong or slightly wrong, please feel free to tell me in the comments.

Checking Out the Cristianitos Fault

Cristianitos Fault san onofre state beach

Hey! Have you ever seen an earthquake fault line? No? Well, today is your lucky day! Referred to as the Cristianitos fault, you can walk right up to it over at San Onofre State Beach.   Now I need to state this fact upfront so there will be no confusion. I am not a geologist; therefore, please be patient with me. If I make an incorrect claim, do not hesitate to correct me in the comments at the end of the post. I love to learn new things and will not be offended at all. Several references have helped me tremendously, but I have left them below. I encourage you to check them out!

Let’s take a trip to San Onofre State Beach (my favorite beach in San Diego) and investigate the Cristianitos fault line. As a bonus, I will highlight other unique geological features here at this fabulous State Beach.

One more thing. Did you know that the San Onofre Nuclear Generating Station (SONGS) is less than 800 yards away from this earthquake fault line?

Wait, what?! A nuclear generating station? Next to a fault line?

SONGS is no longer active and has been decommissioning for several years now. But obviously, the question is, why build a nuclear power plant right next to an earthquake fault line? (Click on the above link for more detailed decommissioning information.)
