The tremor left a 200-foot long/10-foot deep crater on the road. by Dr. Nitish Priyadarshi It is for the first time in earthquake history of Jharkhand that the earthquake, which jolted North and Eastern India on 19th September, left a 200-foot long crack on the NH-75 in Latehar district, disrupting traffic. The tremor left a 200-foot long/10-foot deep crater on the road disrupting traffic near Sikni Colliery. It came as surprise as the area is treated geologically as the most stable cratonic block related to tremors. According to the local administration it was due to Sikni coal mines near that highway. They said that the mining has created instability of the upper surface of the earth of near by areas and the cracks were the multiple effects of both mining and tremors. If it is true then most of the areas of the Jharkhand State where the coal mining are rampant are under tremendous threat in future.

These methods are concerned with forecasting earthquake of a particular intensity over a specified locality within a specified time limit. by Dr. Nitish Priyadarshi Tectonic earthquakes are attributed to rupture in the rock masses which occur following accumulation of strain. Earthquakes present a frightening experience in the lives of men. The disaster strikes suddenly, similar to that of lightning, tornadoes or nuclear explosions. It is estimated that an average, about 15,000 human lives are lost every year, while in a singe year of 1976 about 200, 000 were killed by earthquakes in china, Guatemala, Philippines and in other parts of the world. The damage to property runs into billions of dollars. Earthquakes generate a variety of effects. Some are temporary, such as the shaking ground, swinging objects, rattling windows and oscillating trees. Permanent effects include damage to buildings, transportation, water supply systems and the landslides. Till today there is no perfect method t...
