I've always heard we could have something around an 8. That such a thing is a >1000 year event, but also that we are more than 500 years overdue.
So An Earthquake Just To Keep Us On Our Toes?

I think 8 is near the top end of what’s possible.
No it’s not. 18 mm is .71 inches.
10mm per centimeter. 2.54 cm per inch (or 25.4 mm per inch).
Still a big movement though.

Probably a good thing this is my first day of work from home.
What's it called when an earthquake happens in a place that used to be an ancient lakebed? It happened to Mexico City. Well anyway, The Salt Lake Valley is an ancient lakebed. I think I felt a little bit of that effect after the main shaking was over, there was a bit of "my girlfriend is getting out of the waterbed" feeling where there were some waves that lasted for several seconds. In a major earthquake that reverberation can cause a lot of additional damage.

o fml. I could've sworn there were 16mm in an inch...Aren't there 16 little marks on a ruler per inch?
Thanks.
Yes, there are. The standard ruler or tape measure breaks down the inch into sixteenths. 1/16” does not equal 1mm.

That effect is sometimes called liquifaction.
But you don’t need to be on an ancient lake bed to have that kind of feeling. Different soil and sediment environments can result in magnifying the amplitude of a wave... sorta by allowing it to roll with a more steady rhythm.

On the channel 2 news they said this rumor is circulating around and according to seismologists they've spoken to it's absolutely not true. They expect aftershocks to continue for the rest of the day and possibly even the next few days but nothing even as big as the original earthquake.
