INDIA NEWS - Not only Sikkim and the Northeast as a whole, more than half of the country is earthquake prone. In twenty years the Sunday evening earthquake in Northeast was the worst, measured 6.8 on Richter scale and the epicenter was Sikkim.
According to Central Seismological Observatory data, the entire region is increasingly unstable. In 2009 there were 34 earthquakes there, 26 in 2008, 26 again in 2007 and in 2006 it was hit 23 times.
Northeast, Punjab, Rann of Kutch, parts of Kashmir and central Himalayas fall in Zone 5 of areas most prone to quakes. Jammu, Delhi, Bihar, Maharashtra and Indo-Gangetic basin is in Zone 4, slightly less risky but extremely dangerous. Zone 3 areas have moderate risk where as Zone 2 is the safest.
Few days before Zone 4 Delhi experienced 4.2 intensity earthquake. However, scientists deny of any connection between the two quakes.
RS Dattatrayam, Seismologist at India Meteorological Department said, "It is incorrect to connect a 4.2 intensity earthquake in Delhi with a 6.8 one in Sikkim."
