Aerial photographs were collected in the days immediately following the 4–5 July 2019 Ridgecrest earthquake sequence (e.g., Barnhart et al., 2019) along the publically accessible sections of the surface ruptures south of California 178. These photos were then used to produce structure‐from‐motion point cloud models and orthophotos with resolutions varying from ∼1 to 20cm/pixel⁠. Here, the models are released and initial observations of the nature of the surface ruptures are presented.
