The Richter scale is logarithmic. The difference between a 5 and a 6 is not 1x, it is 10x. The difference between a 5 and a 7 is not 2x. It is 100x.

So a .3 increase in the size is 3x.

The quake broke other records, too, as outlines in journal Science. The rupture extended about 180 km, by far the longest known rupture.

How far back could the records go?

Guessing they would need three direction seismometers to record the depth?

I understand how the Richter scale works.

But an increase from 5 to 5.3 or 8 to 8.3 is not 30% is it?
