“…The fault has long been known to be an oblique-slip fault, with significant component of vertical movement (e.g., Hsu, 1962;Ho, 1986Ho, , 1988Chen, 1988 This is exactly coincident with surface ruptures of 1951. Along this reach, the fault has been rapidly creeping for at least 20 years (e.g., Yu and Liu, 1989;Angelier et al, 1997;Chow et al, 2001;Lee et al, 2001). Our discovery of 1951 ruptures here demonstrates that the fault fails by both creep and by seismic rupture.…”

“…Creepmeter measurements show that the Longitudinal Valley fault zone near the town Chihshang is creeping obliquely at a rate of about 25 mm yr-1 (Angelier et al, 1997;Lee et al, 2001). Inversions of GPS data across southern Taiwan also indicate that the Longitudinal Valley fault is a major active structure (e.g., Hsu et al, 2003).…”

“…The Chihshang rupture is along a portion of the fault that is well known for its rapid creep behavior (e.g., Yu and Liu, 1989;Angelier et al, 1997;Chow et al, 2001;Lee et al, 2001). Since the fault ruptured during the 1951 earthquake, one might well suspect that current creep is not releasing all strain accumulating in the blocks adjacent to the fault, and that creep should be viewed as retarding rather than eliminating the prospect of future seismic ruptures there.…”

“…5 both above and below). As the 25 concrete dykes are manmade and very recent, it is easy to reconstruct and inverse the deformation following the Angelier's methodology settled along the Longitudinal Valley Fault (see also Lee et al, 1998Lee et al, , 2000Lee et al, , 2001Lee et al, , 2003Lee et al, , 2005Lee et al, , 2006. One may note that we cannot recognize clearly in the topography the trace of the Hengchun Fault as a unique straight line thrusting (see Fig.…”

Abstract. Geometry, characterization and quantification of active faults are major concern in Taiwan, especially following the major Chichi earthquake of September 21 st , 1999. Among the targets that still remain poorly known in terms of active 15 tectonics, are the Hengchun and Kenting faults (Southern Taiwan). From the geodynamic point of view, the latter affects the outcropping top of the Manila accretionary prism of the Manila subduction zone that runs from Luzon (N. Philippines) to Taiwan. In order to settle the location, characterization and quantification of the Hengchun fault, we needed to up-date the Chinese Petroleum Corporation (CPC, 1993) and Central Geological Survey (Sung, 1991) existing geological maps using GIS mapping and photo-interpretation of both UAS's acquisition : 1). the very high precision (<50 cm) and resolution (<10 20 cm) Digital Terrain Model, and the 2). the georeferenced aerial photograph mosaic of the studied area. Moreover, the superimposition of the resulting structural sketch map with the new PSI interferometric data acquired through the SAR ALOS 1 images, validated by GPS data, helps to give motions, characterisation and quantification of the displacements along the LOS during the monitoring time-series (2007)(2008)(2009)(2010)(2011). We therefore focus herein on the geometry, the characterization and the quantification of the Hengchun Fault which is an active left-lateral transpressive fault. Finally, as the 25Hengchun ridge face one of the last major earthquake of Taiwan (Dec. 26th 2006, depth: 44 Km, M L =7.0), it is needed to better constrain the active Hengchun Peninsula tectonics in order to prevent major destructions in the near future.

Abstract. Characterizing active faults and quantifying their activity are major concerns in Taiwan, especially following the major Chichi earthquake on 21 September 1999. Among the targets that still remain poorly understood in terms of active tectonics are the Hengchun and Kenting faults (Southern Taiwan). From a geodynamic point of view, the faults affect the outcropping top of the Manila accretionary prism of the Manila subduction zone that runs from Luzon (northern Philippines) to Taiwan. In order to better locate and quantify the location and quantify the activity of the Hengchun Fault, we start from existing geological maps, which we update thanks to the use of two products derived from unmanned aircraft system acquisitions: (1) a very high precision (< 50 cm) and resolution (< 10 cm) digital surface model (DSM) and (2) a georeferenced aerial photograph mosaic of the studied area. Moreover, the superimposition of the resulting structural sketch map with new Persistent Scatterer Interferometric Synthetic Aperture Radar (PS-InSAR) results obtained from PALSAR ALOS images, validated by Global Positioning System (GPS) and leveling data, allows the characterization and quantification of the surface displacements during the monitoring period (2007)(2008)(2009)(2010)(2011). We confirm herein the geometry, characterization and quantification of the active Hengchun Fault deformation, which acts as an active leftlateral transpressive fault. As the Hengchun ridge was the location of one of the last major earthquakes in Taiwan (26 December 2006, depth: 44 km, M L = 7.0), Hengchun Peninsula active tectonics must be better constrained in order if possible to prevent major destructions in the near future.
