Abstract

Frequency time analysis of surface wave and co-seismicity are the key points to analyze the different characteristics of subsurface feature beneath the Himalaya Gharwal region. The different parameters group wave velocity, polarizing anomaly, gravity offset for NW of Himalaya Gharwal region are studied through earthquake data analysis from 2008 to 2012 with magnitude ? 4.5. The co-seismicity characteristic is analyzed by superconducting gravimeter data, which is most sensitive to the long period signals (gravity tides with period longer than 6h). The analysis result for co-seismicity is found approximately 40 nms-2 . The frequency time analyze of surface wave indicates the spectral content of signal changes with time. The study of group velocity anomalies correlate the major geological structure of the region, which is useful to prepare the of tomography map for the study of crustal structure.
