According to me in older generations there were very less earth quakes when compared to the present situations

there were some estimations about earth quakes such that atleast there are 13-17 earth quakes happening month of which 2 of them are major i.e.,a rictor scale reading of 6-7.5

now a days you are able to notice that there are new types of earth quakes happening throughout the world such as TSUNAMI why is the change so . what made rapid increase in earth quakes level ?

even the concept of the 2012 dec 21 include earth quakes ,tsunamis. Is there any alternate to offend from an earth quake other than hiding beneath the tables and benches?
