Subsurface Structure Investigation of the Longitudinal Valley, Eastern Taiwan from High-Resolution Seismic Reflection Data

  1. The profile J north of the Peinanshan in Luyeh reveals the east-dipping Luyeh fault, and the undulations of the alluvium strata are observed as a result of the fault.

  2. The deformation and tilting of the sedimentary strata in the southern Longitudinal Valley is inferred to relate to the collision toward the northwest from the southern Costal Range and the reverse movement of active faults in the LV.

Seismic reflection survey in eastern Taiwan

作者:

Seismic reflection survey in the northern part of the Longitudinal Valley, the suture zone, in eastern Taiwan

  1. In this study, we found that beneath the longitudinal valley, there are about 2000 m thick of sedimentary beddings laid on top of the basement dipping to the east.

  2. In fact that only Lingding fault has been found in the section, no other major fault has been discovered.

Study seismic stratigraphy in the alluvium fan

  1. We have completed four seismic profiles with a total of 10.748 km in length and according to the seismic data four unconformities can be identified from seismic stratigraphy analysis.

  2. According to the analysis of sequence stratigraphy, it is found that this area is in a sedimentary cycle from the development of the transgressive system to the high stand system tracts, and from the topographies of the unconformities in different periods it indicates that the river was through headward erosion.

Improving the seismic imaging by using multiple attenuation methods

Improving the seismic imaging in the southern Ryukyu subduction system by using multiple attenuation methods

  1. In this study, we test two sets of multiple attenuation methods: differentiate the physical properties and modeling multiples from sea bed and signal.

  2. We end up using the flow: surface related multiple elimination(SRME), Radon transform, dip-filter and deconvolution.

Fault Investigation Using Shallow Seismic Survey

作者:

Yuli Fault Investigation Using Shallow Seismic Survey

  1. In this study, we combine two types of active source for fault imaging: Minivibe and weight drop.

  2. The reflection signal from weight drop can be recovered is 700 m and from Minivibe is around  2000 m.

  3. We can clearly see the Yuli fault dipping to the east.
