Tectonic plates can be broken into smaller blocks with deformation concentrated at their boundaries. We use remote sensing and field studies to investigate how faulting accommodates deformation at the northern boundary of the Quito-Latacunga microblock (Ecuador & Colombia). We show this boundary is a wide zone characterized by several parallel faults capable of hosting moderate to large (<M7) earthquakes, such as the one in 2022, and which may be influenced by nearby volcanism.
