Abstract

Extensive geoseismological studies of the 26 January 2001 Kutch earthquake have been carried out by Geological Survey of India in an area of 1.2 million sq km. The isoseismal map of the earthquake has been prepared adopting MSK-64 Intensity Scale. Separate studies have been conducted for evaluating the effects of the earthquake on engineered structures, geothermal manifestations and groundwater. A 13-Station MEQ array, in operation for the last two and a half months in the Kutch region, has precisely delineated the aftershock activity. Collation and analysis of data obtained from different sources have enabled understanding of source mechanism of the seismic event.

Abstract

The Upper Permian index species Cyclolobus walkeri is recorded and described from the base of C-Member, Zewan Formation, Guryul ravine, Sri nagar, Kashmir. On the basis of the present record of the Upper Permian C. walkeri (Diener, 1903), C-Member is correlated with the mid-Dzulfian Chhidruan Stage. By extension, the units above and below belong to the Dzulfian series though the existing record of fauna is inconclusive regarding the age of the members B and D.
