Seismology experts from all over the world presented their research papers on the second day of international symposium, organised at the recently inaugurated Institute of Seismological Research,Gandhinagar. Experts talked on the topic -2001 Bhuj earthquake and advances in earthquake science.
Professor Arun K Saraf from IIT Roorkee threw light on the post seismic ground deformation after 2001 earthquake in Bhuj. Apart from this, CD Reddy of Indian Institute of Geomagnetism- Panvel and KM Sreejeeth of Space Application center -ISRO, Ahmedabad discussed the use of GPS system in understanding earth patterns and results acquired through modern technology.
According to KM Sreejith, the seismic region is now expanding towards Saurashtra from Kutch, which can be a cause of concern. Saraf showed detail maps of a project conducted by IIT Roorkee to understand the patterns of deformation of land around Bhuj after the earthquake. The project was conducted between 2003 and 2005. Through this project, a clear uplift of land was noticed in many villages of Kutch. "The land got uplifted by almost 8 centimetre, which shows the kind of activity going on beneath the surface," said Saraf.
He added that the data for such project was collected from European Space Agency, because India doesn't have such advanced satellites. "We didn't have enough data till now. So to fulfil this need, India will soon launch its own microwave satellite to monitor seismic activity," said Saraf.
On the mysterious explosions heard through out the region, Prof Saraf said that it is a result of activity beneath the earth's crust. "It is good thing. This means energy is getting released in small pockets without harming anyone" said Saraf.
He compared the earthquake prediction to predicting heart attacks. "Just like you can't predict the time of a heart attack, you cannot predict when earthquake will strike," he said.
