Complex rupture of the M6.3 2015 March 10 Bucaramanga earthquake: evidence of strong weakening process

We use seismic waves for a magnitude 6.3 intermediate-depth (160?km) earthquake in the Bucaramanga Nest, Colombia, to infer a complex rupture process with two distinct stages, characterized by different rupture velocities possibly controlled by the evolution of strength on the fault. Our integrated...
