| Research Abstract |
1)Recognition of detailed fault trace and its geometrical pattern in the Himalayan front
Based on photo interpretation focused on the Nepal Himalaya, I recognized the 50-km-long fault system with right lateral strike slip behind the Himalayan front newly. The founding leads that not mega thrust along the Himalayan front, but strike slip fault system across the range played an important role to release to the strain of the plate collision.
I interpreted the distribution of active fault in Bhutan and show its geometrical pattern.
2)Clarification of characteristics of tectonic landform
I surveyed tectonic landform in Gelephu, southern Bhutan to clarify its characteristics where most prominent landform developed.
3)Reconstruction of seismic history accompanied with surface rupture, NW Himalayan front
It is highly possible that the mega thrust along the NW Himalayan front for 430 km length generated two earthquakes in 16 century with dividing into two extents for 200 km in the east and 230 km in the west.
