“…The present conclusion also gains support from the various earlier studies that the reactivated basement faults have acted as loci for the earthquakes in Latur in 1993 (Rajendran et al, 1996) and Bhuj-Kutch in 2001 (Biswas, 2005;Karanth and Gadhavi, 2007). Further, present study has also provided a lead that it can be used for groundwater and engineering foundation related issues.…”

ABSTRACT:The study area falls in the southern part of the Indian Peninsular comprising hard crystalline rocks of Archaeozoic and Proterozoic Era. In the present study, the GIS based 3D visualizations of gravity, magnetic, resistivity and topographic datasets were made and therefrom the basement lineaments, shallow subsurface lineaments and surface lineaments/faults were interpreted. These lineaments were classified as category-1 i.e. exclusively surface lineaments, category-2 i.e. surface lineaments having connectivity with shallow subsurface lineaments and category-3 i.e. surface lineaments having connectivity with shallow subsurface lineaments and basement lineaments. These three classified lineaments were analyzed in conjunction with known mineral occurrences and historical seismicity of the study area in GIS environment. The study revealed that the category-3 NNE-SSW to NE-SW lineaments have greater control over the mineral occurrences and the N-S, NNE-SSW and NE-SW, faults/lineaments control the seismicities in the study area.

“…If similar rates prevail in the Kachchh region, the strain contraction released by the Kachchh event would require c. 100000 years for its renewal, an interval long compared with the time needed to erode the 1819 scarp, a problem common to Peninsular India earthquakes (Rajendran et al 1996). It is therefore unlikely that future large events will recur soon near the epicentre of the 1819 Kachchh event.…”

The 16 June 1819 Rann of Kachchh earthquake was felt throughout much of India. Although significant vertical movements of the ground caused flooding of regions near sea level, damming of a distributary of the Indus river, widespread liquefaction, and a local tsunami, the geometry of the fault plane has hitherto remained obscure. Dislocation models based on deformation data gathered 7 and 25 years after the earthquake suggest that a near-surface reverse fault slipped locally more than 11 m, and that rupture extended at least 80 km along strike. Estimates of maximum uplift and depression during the earthquake yield similar, but not identical, solutions to those based solely on a levelling profile across the zone of uplift, known as the Allah Bund. The inferred 50-70~ fault plane beneath the Allah Bund is unfavourably steep for reverse faulting, and its down-dip width (6-10 km) short for slip exceeding 10 m. Some forms oflistric fault geometry are also consistent with the observed surface deformation fields, with increased fault width (15-25km) and similar coseismic slip. A geometric moment magnitude of M = 7.7 + 0.2 is obtained from the inferred slip parameters, assuming uniform along-strike slip, consistent with a magnitude estimated empirically from the intensity distribution. Although a recurrence of the Kachchh earthquake is unlikely soon because of low inferred contractional strain rates in the region, the westward continuation of the Kachchh rift zone could host future ruptures contiguous with the 1819 event, with important consequences for the city of Karachi.

“…Rastogi (1994) argued that the incremental stress due to Makni reservoir was too small to trigger the Killari earthquake. Rajendran et al (1996) and Rajendran and Rajendran (1997) strongly advocated that the Killari earthquake was generated by reactivation of an existing fault in the area, and not a reservoir triggered event.…”

“…The most spectacular effect was the ground deformation; scraps of varying height (few cm to 80 cm) appeared at several locations along the 1 km long discontinuous rupture in E-W direction between the Killari and Talni villages. The deformation zone had been the site of many geophysical investigations as well as trenching and drilling (Rajendran et al, 1996;Gupta and Dwivedi, 1996).…”
