The risk of a large earthquake was well known beforehand . In 2013 , in an interview with seismologist Vinod Kumar Gaur , '' The Hindu '' quoted him as saying , " Calculations show that there is sufficient accumulated energy in the Main Frontal Thrust , now to produce an 8 magnitude earthquake . I can not say when . It may not happen tomorrow , but it could possibly happen sometime this century , or wait longer to produce a much larger one . " According to Brian Tucker , founder of a nonprofit organization devoted to reducing casualties from natural disasters , some government officials had expressed confidence that such an earthquake would not occur again . Tucker recounted a conversation he had had with a government official in the 1990s who said , " We do n't have to worry about earthquakes anymore , because we already had an earthquake " ; the previous earthquake to which he referred occurred in 1934
