The number of seismic tremors precursor to massive earthquakes is increasing exponentially as the world moves towards 2012. (2013)

At least 136 tremors were recorded all over the world by seismologists between December 9 and 16 and these shocks were concentrated all along plate boundaries and majority of them along the Pacific and Indian ones.

Compared to earlier years, the earth is showing a pattern not experienced by humans although such unusual phenomena is not uncommon to the planet, Prof Chandrasekharam, Earth Science department of IIT here said while explaining the earthquake record for the period.

"This apparently shows the dynamic changes that the earth is undergoing internally. A large amount of scientific data is pouring-in with respect to such changes taking place within the earth," he said.

One of the most interesting phenomena noticed recently, is the shifting of the present magnetic pole of the earth towards Russia. A major shift of the pole is recorded by palaeomagnetist Joseph Stoner from Oregon State University, who announced it last week.
