Short summary
Coseismic landslides often cause loss of life and property damage. Accurately mapping hazards is very important and challenging work. This paper considers the roughness and size effect of the potential sliding surface unloading joint and then presents an improved method of Newmark analysis for mapping hazards of coseismic landslides. The approach is verified using the Mw 6.1 Ludian earthquake in 2014 and compared with a conventional Newmark analysis using area under the curve analysis.
