Fissures from lateral spreading located within farmland and beside an ephemeral stream, also being used as farmland. A Post-earthquake imagery. B High-contrast imagery showing fissures. Deformation structures contained by white boxes. C Rehabilitated farmland 6 months after earthquake without evidence of lateral spreading. D Cross-section from drone-generated DSM showing the largest vertical offset due to the subsidence. Transect is indicated by the red line
