Despite major quakes and repeated tremors, tsunami did not wreck the world on Wednesday. Unlike the situation of 2004, the earth plates had moved horizontally and not vertically during the quakes which rocked Indonesia and Sumatra regions on Wednesday. In 2004, the plates had moved vertically which caused devastating tsunami in which 2.4 lakh people had died worldwide. In India, more than 15,500 had died.
Tsunami warnings were lifted at around 4 pm. Fear of getting bruised by wrath of nature was dimmed when the tsunami didn't hit Greater Nicobar where massive waves were supposed to reach within half an hour of the quake at 2:08 pm.
Central government alerted all officials to beef up security at all beaches in Chennai where tremors were felt repeatedly. Orissa government also vacated Puri beaches. Kerala security officials alerted all fishermen about tsunami warnings.
Kolkata metro services were stopped and all high-rise buildings were vacated following the tremors and Indonesian quakes measuring 8.6 in the Richter scale.
