Description

Laser imagery technique is applied to obtain comprehensive features of a typical reverse fault (the Senya fault in NE Japan) and strike-slip fault (the Adera fault in Central Japan) We test several methods for obtaining fault slip from detailed DTM images. Using the visual analyzer“ Geo-Graphia”, a series of three-dimensional laser imagery is processed around the Senya hill, especially along the surface fault ruptures associated with the Rikuu earthquake in 1896.<BR>We compared amount of fault slips along the fault ruptures measured by previous field studies with those obtained by automatic and manual topographical profiling using detailed DTM. Three-dimensional laser imagery is also processed along the Adera fault, and slip vectors are restored based on successively faulted terrace risers around Sakashita town.
