[SSS13-P33] Broadband Microtremor Array Exploration at and around Tribhuvan International Airport, Kathmandu, Nepal
Keywords:Gorkha earthquake, Kathmandu Valley, Broadband Microtremor Array Exploration
In this poster session, we will report the results of analysis of the microtremor array exploration at and around TIA and NAST, and a hard rock site (Chobar) that we have conducted Dec. 2018 following the above mentioned activities.
The attached figure shows the configuration of observation sites and a summary of the dispersion curves of Rayleigh waves. In the legend, BDR (red circles) shows the results given by Hayashida et al. (2018, SSJ-Fall) using tele-seismic surface waves, CHB (red “x”s): the phase velocities estimated on the outcropped bedrock of the Chobar hill.
