Some field-based studies reported that the total length of the co-seismic surface rupture zone is only 200 240 km, (e.g. Liu-Zhang et al., 2009; Xu et al., 2010), while others have reported that the total length of the co-seismic surface rupture zone is up to ∼285 300 km (e.g. Lin et al, 2009, 2010).
Rasmussen et al.
