    Seismological Evidence for Intra-Crustal Low Velocity and Thick Mantle Transition Zones in the North-West Himalaya
    Author(s): Chinmay Haldar*, Narendra Kumar and Kalachand Sain

    The Himalayan region witnesses several natural hazards like earthquakes and landslides due to the continental collisions between the Indian and Eurasian plates. This has given rise to extreme topographic variations throughout the Himalayan belt. The Kumaun-Garhwal region is a classic example of such geological consequences and is prone to several earthquakes. High-quality three-component teleseismic waveform data recorded at seven seismological stations operated by the Wadia Institute of Himalayan Geology (WIHG) are used to investigate the detailed subsurface of the crust-mantle boundary, the intra-crustal Low Velocity Layer (LVL), and the upper mantle discontinuities beneath the Kumaun-Garhwal, North-West Himalaya. The results, derived from the inversion of the stacked P-Receiver Functions (PRFs) of individual stations using the neighborhood algorithm approach, s.. View More»
