A magnitude 8 earthquake is 100 times stronger than a magnitude 6 quake.
A magnitude 6.0 earthquake is about 1.4 times stronger than a magnitude 5.9.

A magnitude 9.2 earthquake is 794 times bigger on a seismograph than a 6.3 nut is 22387 times stronger in terms of energy released.
By definitiona an aftershock is always smaller than the larger earthquake that preceeded it. If an earthquake then occurs that is of larger magnitude and related to the prior seismic activity it is redesignated as the mainshock and all pre-recording quakes are re-designated as foreshocks.
Seismic energy increases by a factor of about 31.6 for each increase of magnitude, so a magnitude 3 earthquake has 31.6 times more energy released than a magnitude 2 earthquake.
A magnitude 9 earthquake is 10,000x stronger than a magnitude 5.
A magnitude 6.0 earthquake is about 1.4 times stronger than a magnitude 5.9.

My understanding of the magnitudes of earthquakes is that each decimal point is equal to a magnitude of strength 10x more than the previous number. Example would be that a 4.2 earthquake is 10x stronger than a 4.1 earthquake. Therefore, a magnitude 8.5 EQ is 100x stronger than a 7.5 EQ.
Answer #1:by a magnitude of 2======================Answer #2:by a factor of 100
0.3 magnitude
0.3 magnitude
A magnitude 9.2 earthquake is 794 times bigger on a seismograph than a 6.3 nut is 22387 times stronger in terms of energy released.
The Richter scales grows by powers of 10, so an increase of 1 point means the strength of an earth quake is 10 times greater than the level before it; for example, and earthquake registering 3.0 on the Richter scale is 10 times stronger than a quake that registered 2.0
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.
