density affects the death count as well. Prediction of earthquake Long term forecasting founded on the knowledge of place where the earthquakes have taken place previously. In order to study the occurrence of earthquake, the knowledge of the current tectonic setting, geological records and the history records are analyzed critically to establish locations and occurrence intervals of earthquake. Pale seismology and seismic gaps are the most crucial aspect when carrying out analysis. Paleoseismology is
