I'd say it's mostly when referring to something big. Earthquakes are often described as "good ones" when they are big enough to rattle us. Normally a 5 doesn't rattle most people, but these aftershocks are too frequent right now so there's a few of us that consider them "good ones" right now, lol.

This was by far the worst one I've been through. Being on the 12th floor of a building that is built on sand sure did some damage - but my friends in the Valley have it worst. Their houses literally fell of the foundations and cracked in two - we're hoping FEMA will help out, because they cannot afford to fix the houses themselves...

And I've posted this on all facebook groups I'm in, but I'll post it here too - baby child proof locks keep dishes safe in your kitchen. I learned that a few years ago.

We have the non-slip pads in our cupboards and none of our dishes fell out. We also have the soft close doors and they seem to have a little bit of tension that helped keep them closed. I opened one cupboard that has glass water goblets on the top shelf and they had danced their way to the very edge of the shelf and were just held back by the closed door.

That's a really good idea - thanks for sharing. I'm going to do it and share with one of my sisters that lives in Eureka CA on the Cascadia subduction zone.

Compared to 1964 this was a very mild earth quake. I would be curious if this quake was enough to relive the plate tension or if we are still due for a real quake. 1964 was a 9.2 vs what we just had was a 7 or 7.2 and if I remember correct the ricter scale is a log plot so it is exponential and not linear so a 9.2 was hell.

Any quake is relieving tension in a fault, for a while.

7.0 range is definitely in "real quake" territory, some of the areas that are susceptible to liquefaction, or areas that are transmitting the sound waves had quite a bit of damage. Eagle River and Chugiak got it good, that's for sure. We're still having aftershocks, but I don't feel them where I am, but over in ER? Oh yeah, they're feeling them still.

I agree that a 9.2 is pretty unimaginable, unless you've been through it.

I wasn't living there in '64 but a close friend of mine grew up there and has told me vivid memories of it. She happened to be outdoors at the time and watched their house crumble into rubble. Her sister was in the house, searched for, but never found.

The strongest quake I've been in was the 1971 San Fernando (or Sylmar) now categorized as MMI XI. In Richter terms about 8. Not too much damage to our house probably due to the direction of movement, its orientation and style of construction.

I posted an article that video was linked in in the other EQ thread but it was sort of hard to get to. This short clip has an excellent graphic illustration of how the Richter scale increases exponentially. Each successive magnitude is 33 times larger than the previous one, so the 9.2 in 1964 was roughly 1,000 times larger than the one a couple weeks ago.
