And isn't earthquake measurement logarithmic? (Don't hate me for being ignorant. Please?)
Yes, it is. That is what SBM means by "an order of magnitude." One order of magnitude is a fator of 10. Thus, 10 is an order of magnitude bigger than 1, and 100 is 2 orders of magnitude greater than 1. A 4 point earthquake is an order of magnitude (10 times) stronger than a 3 point earthquake.
I'll attest to that. You can feal a 3, but it doesn't do much. A 4 is not only noticable by movement, but by sound. The highest I've been in was the Northridge Earthquake, which was a 6.7. You feel, hear and notice that. Big time.
