Actually, if you take the mean or average of the Loma Prieta, it could be called a 7.0 (rounding down). Then the difference between your 5.7 and the 7.0 would be around 20X.
Believe me, it really shook things up. We had a pool at that time, and almost half of the water was lost (almost straight in the air). Our next door neighbor happened to be in her driveway at the time, looking toward the fence of our back yard. She said that she saw the plume of water shoot 25-30 feet in the air above our backyard fence.
Flip-flops and lawn furniture were all washed to far ends of the
back yard.

Minor league for you, but we are bush league in Utah when it comes to earthquakes. I cannot imagine a 6.7 being 10X what was happening this morning.From: Bill PrinceSent: Wednesday, March 18, 2020 11:00 AMTo: af@af.afmug.comSubject: Re: [AFMUG] OT earthquakeA 5.7 is minor league. You should try out a 7. The 1989 Loma Prieta was a 6.9 or 7.2 depending on which scale you use. Either way, it created a pretty major disruption around here.

5.7 Biggest I have ever felt. About 15 miles from my home. I think downtown SLC got it stronger than I did. Lots of aftershocks.
