Math and earthquakes in Japan


The volume of the earth is approximately 1 sextillion cubic meters. To observe the movement of the earth, scientists create computer systems that analyze the earth by dividing it into cubes. In this case, taking cubes of 1 kilometer edge, the system should analyze 1 trillion cubes. Because of this immensity of mathematical calculations, earthquake prediction is difficult.

The 2011 earthquake that hit Japan, pointed at the Richter Scale at 8.9, is equivalent to the intensity of the explosion of nearly 1 billion trucks loaded with 32 tons of TNT explosives.
