Subcontinental lithospheric mantle discontinuities beneath the Eastern Himalayan Plate Boundary System, NE India
Autor: Jashodhara Chaudhury, Supriyo Mitra
Publikováno v: Geophysical Journal International. 233:2155-2171
We use P-wave receiver function (P-RF) analysis and joint inversion with Rayleigh wave group velocity dispersion data to model the shear-wave velocity (Vs) structure of sub-continental lithospheric mantle (SCLM) discontinuities beneath northeast (NE)

Crustal Structure of the Jammu and Kashmir Himalaya
Autor: Supriyo Mitra, Swati Sharma, Debarchan Powali, Keith Priestley, Sunil Wanchoo
We use P-wave receiver function (P-RF) analysis of broadband teleseismic data recorded at twenty stations spanning the Jammu-Kishtwar Himalaya, Pir Panjal Ranges, Kashmir Valley, and Zanskar Ranges in Northwest Himalaya, to model the seismic velocity

Radially anisotropic shear-wave velocity structure of northern India, Himalaya and Tibet
Autor: Monumoy Ghosh, Arijit Chakraborty, Siddharth Dey, Inashua Kharjana, Shubham Sharma, Sankar N. Bhattacharya, Supriyo Mitra
3-component regional waveforms for ~14700 raypaths sampling India, Himalaya and Tibet, have been used for multi-taper polarization analysis of surface waves between periods of 10 and 120 s. Rayleigh (LR) and Love (LQ) wave energy arriving at the stat

Detection and (re)location of earthquakes using Jammu And Kashmir Seismological NETwork
Autor: Sk Shamim, Ayon Ghosh, Supriyo Mitra, Keith Priestley, Sunil Kumar Wanchoo
Broadband waveform data from the recently established Jammu And Kashmir Seismological NETwork (JAKSNET) has been used to detect and locate earthquakes in the Jammu and Kashmir (J&K) Himalaya. Continuous data recorded by the network between 2015 and 2

The Main Himalayan Thrust beneath Nepal and Southern Tibet illuminated by seismic ambient noise and teleseismic P wave coda autocorrelation
Autor: Hari Ram Thapa, Surya Pachhai, Abdelkrim Aoudia, Daniel Manu-marfo, Keith F. Priestley, Supriyo Mitra
Nepal is an actively deforming region due to its tectonic setting that hosts many destructive earthquakes including the most recent 2015 Gorkha earthquake of magnitude 7.8. To better understand the physics of earthquakes and their precise location as

Detecting Microseismicity in Jammu and Kashmir Himalaya Using Template Matching Technique
Autor: Ayon Ghosh, Blaž Vičič, Supriyo Mitra, Keith Priestley, Sunil Kumar Wanchoo
We study microseismicity in the Kashmir seismic gap from broadband data of the Jammu and Kashmir Seismological NETwork (JAKSNET) using the template-matching technique. Template-matching is done by the Python routine ‘PyMPA’ (Vuan et al. 2018) to

Seismic Attenuation of India, Himalaya and Tibet using Lg-coda waves
Autor: Dibyajyoti Chaudhuri, Ayon Ghosh, Shubham Sharma, Supriyo Mitra
We present maps to show the lateral variation of Lg coda attenuation at 1-Hz across India, Himalaya and Tibet. We use vertical component waveforms from regional earthquakes (epicentral distance5) recorded by the IISER-K seismological network, ones op

3D transversely isotropic shear-wave velocity structure of India and Tibet from joint modeling of Rayleigh and Love waves group velocity dispersion
Autor: Siddharth Dey, Monumoy Ghosh, Rupak Banerjee, Shubham Sharma, Supriyo Mitra, Shankar Bhattacharya
We use regional Rayleigh and Love wave data, from 4750 earthquakes (M >= 4.0) recorded at 726 stations across India and Tibet, to compute fundamental mode group velocity dispersion between 10 s and 120 s, using the Multiple Filter Technique (MFA). Th

A Report on Broadband Seismological Experiment in the Jammu and Kashmir Himalaya (JAKSNET)
Autor: S. K. Wanchoo, Debarchan Powali, Shubham Sharma, Swati Sharma, Liyaqet Ali, Supriyo Mitra, Keith Priestley
Publikováno v: Seismological Research Letters. 91:1915-1926
A significant Himalayan seismic gap lies between the 2005 Mw 7.6 Kashmir earthquake and the 1905 Mw 7.8 Kangra earthquake, across Jammu and Kashmir, in the northwestern Himalaya. The last great earthquake in this region was the 1555 Mw∼8.0 earthqua
