Jan 26, 2001 · The Bhuj earthquake showed that peak horizontal accelerations (PHAs)≤0.2 g were generally safe. PHAs>0.2 g were hazardous, when unconsolidated granular foundation soils were water saturated. N values of <20 are indicative of susceptibility to soil liquefaction. The Bhuj experience showed that alluvial foundation soils, subject to a PHA>0.2 g ...
The 2001 Bhuj earthquake in Gujarat resulted in the death numbering up to 20,000. The major damage and loss was at Ahmedabad, which is at a distance of about 225 km from the epicenter. Gujarat is divided in three zones by the zonation map of India as zone III, IV and V with expected intensities of VII, VIII and VIIII.
Feb 1, 2015 · Mishra and Zhao (2003) infer that the epicenter zone of Bhuj earthquake is associated with high crack density, high saturation and high porosity which suggests the presence of fluid filled, fractured rock matrix which might have contributed the earthquake. 2-D inversion of broad-band MT data of two profiles by Chandrasekhar et al. (2012) revealed a thick (∼3 km) highly conductive (1–4 ohm-m) surface layer of fluviomarine Mesozoic–Cenozoic sediments.
Nov 15, 2008 · The Bhuj earthquake was the largest intra-continental earthquake instrumented by modern seismic observation. The fault plane solution and aftershocks of the Bhuj mainshock suggest predominant reverse motion on the south dipping fault ( Antolik and Dreger, 2003 , Kayal et al., 2002a , Negishi et al., 2002 ).
Jul 25, 2003 · Quantitative estimates of the crack density (ϵ), saturation rate (ξ) and porosity (ψ) parameters from seismic velocities (V p, V s) and Poisson’s ratio (σ) in the 2001 Bhuj earthquake area in western India indicate that the 2001 Bhuj earthquake hypocenter is associated with high-ϵ, high-ξ and high-ψ in the depth range of about 23–28 km, extending 15–30 km laterally. These anomalies may be due to a fluid-filled, fractured rock matrix, which might have contributed to trigger the ...
Apr 2, 2012 · The seismic characteristics of the 2001 Bhuj earthquake (Mw 7.6) has been examined from the proxy indicators, relative size distribution (3D b-value mapping) and seismic tomography using a new data set to understand the role of crustal heterogeneities in rupture initiations of the 2001 Bhuj earthquake of the Gujarat (India), one of the disastrous Indian earthquakes of the new millennium.
Nov 1, 2002 · The Bhuj earthquake of 26 January 2001 was the most disastrous earthquake experienced in India in recent history. Deaths were in the tens of thousands and injuries were in the hundreds of thousands. Buildings destroyed were in the hundreds of thousands. Several important dams were destroyed and others were damaged.
Feb 20, 2007 · Bhuj–Gujarat's earthquake (occurred on 26th January 2001, M S ∼ 7.9) has been considered as a test case in the validation phase, while a relatively unperturbed period (no earthquakes with M S ≥ 5, in the same region and in the same period) has been analyzed for confutation purposes. To this aim, 6 years of Meteosat-5 TIR observations have been processed for the characterization of the TIR signal behaviour at each specific observation time and location.
Nov 20, 2011 · Highlights 3-D distributions of b- and D2 values are mapped in the 2001 Bhuj earthquake zone. A zone of high b, D 2 and Vp/Vs values is delineated in the main rupture zone (MRZ). Events in the GF (D 2 =1.2b) zone show a poor agreement with the D=2b relationship. Events in the MRZ (D 2 =1.7b) show a fair agreement with the D=2b relationship. While events in the remaining parts of NWF (D 2 =1.95b) show a strong correlation.
Dec 15, 2017 · The 26 January 2001 Mw 7.7 Bhuj earthquake and its subsequent shocks allowed us to study the Fractal and Multi-fractal behavior for the Kachchh rift. A time sequence of earthquake dataset from 2001 to 2012 has been compiled for the present analysis.
