Earthquake in India. India has a long history of earthquakes. But we have not been able to develop a perfect warning system nor have we been able to identify areas that may experience this natural calamity. The worst earthquake that killed more than 3 lakh people was in Calcutta more than two centuries back on October 11, 1737. 300 people were killed in Mathura and Kumaon Hills on September 1, 1803 and 1,000 on June 6, 1828 in Srinagar. Thousands were killed in Kangra in H.P. on April 4, 1905. Records are not available for deaths in Earth tremors that were experienced in Assam, Andamans, Nepal border, Maharashtra, A.P., Kinnaur, Maharashtra, Goa, Srinagar and J & K between 1981 and 1993. But the Indo-Nepal border quake of January 15, 1934 took atoll of 10,700. In 1950, 1,530 died in Assam. But the worst was on May 31, 1935 in which 30,000 died in Quetta. According to a report a thousand quakes occur daily in the world. The intensity is measured on Richter scale developed by Charles F. Richter, an American seismologist in 1935. Most of the earthquakes that occur daily are of a magnitude of 2R and are not hazardous. Most of the damaging ones measure more than 5. Those that cross 7 are most serious. Each (lumber on the Richter scale represents an intensity of ten times more than the previous number i.e. the intensity of a quake measuring 7 is ten times stronger than that measuring 6. Most of the damaging earthquakes in India have been between 6 and 8.5 (Assam in 1950). Worldwide, the Mexico quake of 1985 measured 8.1, of Japan in 1933 and Colombo Equator border in Pacific Ocean in 1906 measured 8.9 the highest recorded anywhere. Richter scale has been considered a traditional system. The modified Mercalli Intensity Scale (MM) classifies earthquakes into 12 categories. The Mexico (1985) earthquake had an MM intensity of VIII to IX. It took 5,000 lives and
