We describe and test a procedure to accurately co-register and correlate multi-temporal aerial images. We show that this procedure can be used to measure surface deformation, and explore the performance and limitations of the technique. The algorithms were implemented in a software package, COSI-Corr (available from the Caltech Tectonics Observatory website). The technique is validated on sever...

The 3 August 2014 Ludian earthquake with a moment magnitude scale (Mw) of 6.1 induced widespread landslides in the Ludian County and its vicinity. This paper presents a preliminary analysis of the distribution patterns and characteristics of these co-seismic landslides. In total, 1826 landslides with a total area of 19.12 km2 triggered by the 3 August 2014 Ludian earthquake were visually interp...

The earthquake-induced displacement of sloping soil mass is an important indicator co-seismic landslide initiation. In this paper, improved Newmark model that considers the accumulation dynamic pore water pressure (DPWP) in caused by both vertical and horizontal ground motions proposed. can quantitatively describe changes seismic yield acceleration near-saturated infinite slopes. Three differen...
