Lateral-Variation of Seismic Attenuation in Sikkim Himalaya

Ajaay Thirunavukarasu, Ajay Kumar and Supriyo Mitra

08 Oct 2016

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....

Active transverse faulting within underthrust Indian crust beneath the Sikkim Himalaya

Himangshu Paul, Supriyo Mitra, S.N. Bhattacharya and G. Suresh

24 March 2015

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..
