It depends.

For the lay person, it has it’s issues.

https://www.sciencedirect.com/topics/engineering/richter-scale

“Magnitude is best known from the historic Richter Scale which gives local magnitude, M or ML, and is widely reported after earthquakes. It correlates with the amount of energy released at the hypocentre for medium-sized local events. (It is important to note that this scientific measure of magnitude may not relate to damage or felt intensity due to distance, depth and other factors.)”

This is why Shindo is a Better system for laypeople.

I experienced many Shindo 1 & 2 while in Japan. They’re amusing.
