Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Centimeter scale drone based structure from motion orthoimagery was collected shortly following the 2019 M6.4 & 7.1 Ridgecrest and 2020 M6.5 Monte Cristo earthquakes. Fractures are mapped at high detail for tens of km along each rupture. Despite similarly ruptured materials and tectonic settings, each rupture displays distinctly different characteristics in not only the overall rupture pattern, but also finer scale fracturing. Ridgecrest ruptures are primarily confined to a few main traces, while MCE are frequently discontinuous fields of numerous distributed cracks. Here examples of these different patterns are presented. We also show our locations for trenching work to commence later this fall.
