A first modeling of dynamic and static crustal strain field from near-field dilatation measurements: example of the 2013 M_w 6.2 Ruisui earthquake, Taiwan

We analyze the high-resolution dilatation data for the October 2013 M_w 6.2 Ruisui, Taiwan, earthquake, which occurred at a distance of 15–20 km away from a Sacks–Evertson dilatometer network. Based on well-constrained source parameters ( strike=217^∘ , dip=48^∘ , rake=49^∘ ), we propose a simple rupture model that explains the permanent static deformation and the dynamic vibrations at short period ( ∼ 3.5–4.5 s) for most of the four sites with less than 20
