A new study, carried out by Dr. Tom Parsons and Aaron Velasco, claimed that big earthquakes do not initiate other dangerous earthquakes around the globe.
However, monstrous earthquakes like the one in Japan generate local aftershocks within a radius.
The study was published in the online edition of ‘Nature Geoscience.’ Dr. Tom Parsons was the leader of the study, and Aaron Velasco was the co author.
To collect enough proof for their theory, they looked at the earthquake records of around the world for the past 30 years, ending in 2009.
During this timeframe, there were 205 huge earthquakes with a magnitude of 7 or greater, and 25,222 moderate ones with magnitudes between 5 and 7.
