Japan had experienced well over 3,000 noticeable earthquakes in just the year 2012, nearly 60 percent of them were aftershocks from last year's massive tremor that devastated the country's northeast, Japanese media reported on Monday.
Quoting the Japan Meteorological Agency, the NHK broadcaster reported that a total of 3,134 quakes had been felt across Japan until Sunday (December 30) which is about 1,000 more than the annual average from 2001 to 2010.
An analysis of seismic waves indicates that there were more than 10,000 noticeable quakes in 2011. While the number of quakes decreased from that of last year, seismologists continue to monitor frequent seismic activity.
They urged people to be on the alert for possible strong quakes with a magnitude of at least 7 or those triggering tsunami.
