Seismic Surface Wave Analysis for Layering Information of the Crust Using Sikim Earthquake
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
Seismic surface wave analysis has performed for Sikim earthquake of magnitude 6.9 occurred on 18 September 2011 of 12:40:48 UTC. Group velocity dispersion has determined by graphical method. A model taking subsurface layer parameters is also constructed to compute the group velocity dispersion by modified Haskell matrix method. Group velocity dispersion by graphical method is then interpreted from model parameters. Some statistical analysis of the model are studied and presented in this research. Interpreted information of the crust for the Sikim region shows that there are four major subsurface layers of thickness 1.0 km, 2.7 km, 3.5 km and 5.5 km.
