N Venkatanathan, research scholar, who is currently undergoing a Ph.D programme in Predicting Earthquake and Aseismic Construction Designing and the man behind the team working on predictions, said he had already presented a report about the Indonesian earthquake on 22 December to members of the Department of Science and Technology, New Delhi.
The 15-member team headed by S K Tandan were in Chennai at that time for a meeting.
Venkatanathan, said, 'we predicted that the disaster will occur on 26 December 2004 at 00:30 (GMT) with 3.54 N latitude and 97.17E longitude, which is located near the coast of Banyak Island, Sumatra, Indonesia, with a magnitude at around 6 to 7. The actual calamity occurred on 26 December 2004 at 00:58 (GMT), with 3.298 N latitude and 95.779 E longitude, located off the west coast of northern Sumatra'.
The difference in distance between the predicted place and the epicentre was 157.11899 km with a time difference of 28 minutes. He also said the team had predicted that the after-shocks would occur at 700 km to the South of the epicentre between 5 pm and 6 pm. This was recorded with permissible error. It occurred at 157 km from the epicentre. That is with the error of 521 km.
