“…Similarly, the evolution of the Lichi mélange along the retrowedge location can be studied at offshore transects south of its current location (e.g. Huang et al, 2008) in addition to the on land exposures. One thing to note, however, is that while most variations from south to north likely represent the changes as plate motion continues, some distinct localities may have small-scale variations that are specific to their locations and not related to the evolution.…”

“…However, micropaleontology study indicates that the igneous blocks in the Lichi Mélange are angular showing block-in-matrix feature without discernible stratification. They are embedded in highly sheared forearc matrix with predominant early Pliocene microfossils (Chi et al, 1981;Huang et al, 2008). In contrast, the igneous pebbles in feeder channel conglomerate beds of the Mutan Formation are Late Miocene age.…”

Spatiotemporal evolution of seismic and aseismic slip on the Longitudinal Valley Fault, Taiwan

et al. 2014

View full text Add to dashboard Cite

The Longitudinal Valley Fault (LVF) in eastern Taiwan is a high slip rate fault (about 5 cm/yr), which exhibits both seismic and aseismic slip. Deformation of anthropogenic features shows that aseismic creep accounts for a significant fraction of fault slip near the surface, whereas a fraction of the slip is also seismic, since this fault has produced large earthquakes with five Mw>6.8 events in 1951 and 2003. In this study, we analyze a dense set of geodetic and seismological data around the LVF, including campaign mode Global Positioning System(GPS) measurements, time series of daily solutions for continuous GPS stations (cGPS), leveling data, and accelerometric records of the 2003 Chenkung earthquake. To enhance the spatial resolution provided by these data, we complement them with interferometric synthetic aperture radar (InSAR) measurements produced from a series of Advanced Land Observing Satellite images processed using a persistent scatterer technique. The combined data set covers the entire LVF and spans the period from 1992 to 2010. We invert this data to infer the temporal evolution of fault slip at depth using the Principal Component Analysis‐based Inversion Method. This technique allows the joint inversion of diverse data, taking the advantage of the spatial resolution given by the InSAR measurements and the temporal resolution afforded by the cGPS data. We find that (1) seismic slip during the 2003 Chengkung earthquake occurred on a fault patch which had remained partially locked in the interseismic period, (2) the seismic rupture propagated partially into a zone of shallow aseismic interseismic creep but failed to reach the surface, and (3) that aseismic afterslip occurred around the area that ruptured seismically. We find consistency between geodetic and seismological constraints on the partitioning between seismic and aseismic creep. About 80–90% of slip on the southern section of LVF in the 0–26 km, seismogenic depth range, is actually aseismic. We infer that the clay‐rich Lichi Mélange is the key factor promoting aseismic creep at shallow depth.
