NB: I could combine several figures of this paper to make the image a bit more meaningful. This would take a bit more time. Please let me know how you feel first.

– Meinong EQ cross-sections

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. (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 along the Dead Sea fault

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.

– I could add something about Tainan anticline. Maybe later since I am running late.
