Earthquake in OK right near my home

[chilidogg]

Everywhere can have quakes. Some places just have them less frequently than others. We're just micro-fleas on a big dog !

Not here in Florida. Ive been here 37 yrs and never saw nothing. Just some normal hurricane blow your damn house over stuff.

Theoretically they can come pretty much everywhere, but mainly they're limited to the seams of the tectonic plates. Don't really have to worry about that over here. =)

Heheh, here's a How to Not Fall Into an Earthquake Fault for the United States.

There was a quake in the Norwegian Sea a little over a week ago, looks like. I ran a few queries through the NEIC database and Florida doesn't have many quakes at all. Looks like there are a lot of itty bitty quakes in the Sweden/Finland area, and over into Russia (I centered on Helsinki), but nothing people would notice.

Normally I'm not an earthquake nut, but I had a few minutes, so yeah.

Most Finns don't know we have earthquakes. I went on for over thirty years thinking that before i got set right. Usually nobody notices anything in their lifetime.

Is there a difference between "earthquake" and "minuscule, almost unnoticeable tremor"?

Have you finished picking up your stacks of fallen discs yet?

Each step up in magnitude means that the shaking is 10 times stronger (the scale is logarithmic).

A 3.0 will feel like a freight train going by next to you.

A 4.0 will feel like a large truck hitting the building.

A 5.0 is enough to make you jump out of your seat and wonder if you should head for better cover, and then its over. Only very minor damage will occur.

A 6.0 shakes for a while longer, and you will definitely dive for cover. It'll scare the heck out of you until it stops. Old buildings with brick and masonry can collapse. Windows may shatter. Your kitchen cabinets will be a mess. But mostly everything is OK.

A 7.0 knocks you on your ass and you'll try to find cover as your shelves and furniture lurch and leap away from the walls, throwing all the contents onto the floor, you can hear the groan of the building moving and stretching, your large appliances are jumping around, and infrastructure (electricity, gas, water, etc.) will collapse for at least a few days.

An 8.0...
