Question

What does a lower number on the magnitude scale mean?

Answer 1

So firstly a magnitude scale measures the size of an earthquake! So the lower number on the magnitude scale means that the earthquake is not that strong and the higher it goes the bigger and stronger it is. No, earthquakes of magnitude 10 or larger cannot happen. No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet!

I hope this helps if you have any question just message me and I hope can I help :)

Answer 2

Richter's magnitude scale – is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale".[2] This was later revised and renamed the local magnitude scale, denoted as ML or ML .
