Convert the magnitude, which represents seismic energy, to mechanical energy (J), and then convert it to TNT explosive (t).
Magnitude

Calculation Formula

Although there are several types of magnitude, moment magnitude is primarily used today. The magnitude M in this library refers to moment magnitude.

\(\normalsize Magnitude\\ \hspace{20px} \log_{10}J=4.8+1.5M\\ \hspace{50px}M:Magnitude\\ \hspace{50px}J:Joule\\ \)

A 1 increase in magnitude results in approximately 32 times the energy, and a 2 increase results in 1000 times the energy. 1 joule is the energy required to move an object 1 meter with a force of 1 newton (1 J = 1 N × m). 1 TNT ton is equivalent to 4.184 GJ.
