Japan is just starting to put back together the pieces from the earthquake and tsunami that occurred almost a month ago on March 11. To make matters worse for them they were just stricken by yet another earthquake on April 7. Granted this was not as severe as the last one, but it still raised concerns. Experts say that this was an aftershock from the March 11th earthquake. This quake measured at a 7.1 magnitude, which is the largest aftershock ever recorded. It originated about 41 miles from Sendai and 73 miles away from Fukushima, both cities were completely ruined from the earthquake and tsunami last month. Although there were no fatalities, there were 132 people that were injured.
