for Richter scale:
The strongest earthquake ever to strike Japan occurred in 1933 and measure on the Richter scale.

since neither nor is given, let

1933 quake than the one in May 1983 which measured on the Richter scale?
-> let be

How many times more severe was this 1933 quake than the one in May 1983:

=>
This means that the magnitude earthquake is times more intense than the magnitude earthquake.
