6 Best Free Online Earthquake Energy Calculator Websites

Here is a list of the best free online Earthquake Energy Calculator websites. Earthquakes are measured on the Richter scale. This scale gives you the magnitude of an earthquake; the more the magnitude the more severe the quake is. It can be hard for an average person to grasp the severity of an earthquake from its magnitude. Energy can help you assert the severity of an earthquake. We are talking about the amount of energy released by an earthquake.

You can easily calculate the energy of an earthquake from its magnitude. This post covers 6 websites where you can do that. These websites feature simple calculators where you can enter the magnitude of an earthquake and calculate its energy. The calculators provide the energy in joules. But it is the equivalent comparisons of these calculators that show the real harshness of an earthquake. All these calculators compare the calculated earthquake energy to equivalent TNT or past incidents like Hiroshima, Nagasaki, the largest nuclear test, etc. Some of these calculators can also calculate the magnitude of an earthquake from the energy. You can go through the post and check these out yourself.
