Landslide in San Francisco neighborhood
Earlier this week, a landslide occurred in San Francisco’s North Beach neighborhood. In the early morning hours of February 27, a cliff composed of greywacke gave way as a 30 foot high section of rock smashed into buildings down below.
Fortunately, no one was injured in the rock fall, but 7 buildings are currently red tagged and over 100 people are currently seeking shelter.
The slide occurred in greywacke that is part of the Franciscan Formation (here is a link to a cool research project done in the formation in 2000), a block of rock from a subduction zone that is Jurassic to Cretaceous in age.
Read on below to see more pictures I took in the area today.
