– Fault slip rate determination:
Determination of the long-term slip rate on the Chelungpu thrust (central Taiwan) based on geomorphic and structural analysis of folded alluvial terraces. More in Le Béon et al (2014) [J. Geophys. Res., 119, doi:10.1002/2013JB010794]
– Characterization of fault geometries:
Investigating the structural setting of the 2016 Mw6.4 Meinong earthquake (southwestern Taiwan) and the geometry of the faults that were triggered in this event, based on geodetic data, field survey of ground surface deformations and structural geology.
Figure caption: (a) Interseismic leveling data and InSAR ALOS-1 line-of-sight velocities (Central Geological Survey 2014; Pathier et al. 2014). (b) Meinong coseismic E-W and vertical displacements (Huang et al. 2016a). (c) Geological cross-section at the latitude of the epicenter. Red faults are inferred to have activated during the Meinong earthquake.

– Paleoseismology:
Deciphering the paleo-earthquake history on the central Dead Sea fault (Lebanon). These images show the wall of a paleo-seismological trench, where relationships between faults and stratigraphy indicate buried ground surface ruptures associated to M>6 earthquakes.
