More than a thousand earthquakes shake Japan from March 11

Tokyo .- More than a thousand earthquakes above 4.5 Richter scale has rocked Japan since the great earthquake of 9 degrees on March 11 rocked the northeast of the archipelago and caused a devastating tsunami which killed more than 28,000 dead or missing. According to the U.S. Geological Survey. UU., Today at 17.00 Japanese time (08.00 GMT) there had been in this country at least 1,001 earthquakes of over 4.5 degrees on the Richter scale.

A spokesman for the Japan Meteorological Agency for his part explained to EFE which 408 earthquakes have a magnitude 5 or greater on the Richter scale and that take into account those of at least 4 degrees, the number could increase tenfold. Of earthquakes recorded since 11 March, a total of 68 have been 6 or more on the Richter scale and another five were at least 7 degrees, the same intensity of the earthquake that left some 300,000 dead in Haiti in January 2010.

The Richter 9 earthquake that does little more than a month shook northeastern Japan was the strongest in this country since measurements began 140 years ago, and was followed by a tsunami with waves up to fifty feet. More than a month after the disaster, the death toll stands at 13,456 and 14,851 are still missing, police at last count.

The tragedy also caused a serious nuclear crisis in Fukushima plant, where workers continue to work day and night to try to cool the reactor core and contain the radioactivity. Japan sits on the so-called Pacific Ring of Fire, so it is relatively accustomed to tremors, most have no serious consequences for the strict building codes in force.

Until March 11, the worst earthquake in recent history in Japan was 7.2 on the Richter scale that struck the city of Kobe in 1995, which killed some 6,400 people.
