Geomorphic parameters are very helpful as they can quickly explain the concerned area, which is going through a tectonic adjustment. For this purpose, four indices were applied to examine active tectonics in Quetta-Ziarat region. These include: sub-basins asymmetry (Af), transverse topography (T-Factor), hypsometric integral (HI) and stream-length gradient (SL). The calculation of three denoted...

The Puqu Fault is situated in Southern Tibet. It is influenced by the eastward extrusion of Northern Tibet and carries the clockwise rotation followed by the southward extrusion. Thus, the Puqu Fault is bounded by the principal dynamic zones and the tectonic evolution remains active alongside. This study intends to understand the tectonic activity in the Puqu Fault Region from the river profile...

[1] We estimate the spatial variation of the seismic parameter t* using teleseismic (epicentral distance = 30 –85 ) P wave spectra of about 200 deep (focal depths > 200 km) earthquakes recorded by 378 broadband seismometers in the United States and Canada. Relative P wave spectral ratios up to 1 Hz for about 63,000 station pairs with high signal-to-noise ratio and impulsive P waveforms are inve...

Assam region is mainly formed by the deposit and erosion process of Brahmaputra River. The frequency seismic events results in landform deformation, which highly influences drainage basin pattern causes anomalies, having a subsequent effect on flood distribution pattern. In present study, morphometric parameters geomorphic indices for are derived from SRTM DEM data 30 m resolution using GIS to ...

Successful scientific theories provide theoretical understanding for reliable deterministic or probabilistic forecasting of events. In the past decades the volume of data obtained within the fields of structural geology and tectonics has increased enormously, but the theoretical understanding of the processes that generate these data has not advanced at the same rate. For example, after decades...

The sub-Himalayan thrust belt is an active thrust wedge which progresses southward over the northdipping Indian plate. The north–south compression resulted in severe deformation of sedimentary rocks in this belt. Distinct thrust geometries and topography have evolved under the interaction between tectonic and erosional environments. To better understand the relationship between tectonics and to...
