Lateral-Variation of Seismic Attenuation in Sikkim Himalaya
We study the frequency dependent attenuation characteristics of the crust and upper mantle beneath Sikkim Himalaya using decay of coda wave amplitude. Data from local earthquakes (mb ≥ 3.0), which originated within the Sikkim Himalaya, and recorded by the temporary network of broad-band stations, have been used for the analysis....

We studied the source characteristics of the 18th September (Mw 6.9) deep focus Sikkim main shock and its major aftershocks to understand the kinematics of deformation of the underthrust Indian Plate beneath the Sikkim Himalaya and its influence, if any, on the active deformation of the overlying wedge..
