my very first Earthquake :o|

[Tjalfe]

I never really thought of this place as being seismically active, but it seems that I was wrong.

it felt like the neighbors we out steamrolling their parking lot again, but it was quiet, except for the actual shaking. nothing too extreme, yet it was strange to feel.

I guess we will know the magnitude and such later on. Apparently it could be felt as far away as Ohio

Yeah I was at work trying to setup a conference room and never felt anything but when I left the room I saw a bunch of people talk about it. Too bad I missed out on the experience.

We felt it at about an R3.0-3.5. We feel quite more than you'd expect because of the faults under Lake Erie & off Cleveland, Ohio. Back in the 80's we felt a strong one epicentered there that swayed buildings and did a great job of "reorganizing" my office

EDIT: as if the quake wasn't enough we just went through a tornado alley special - severe t'storms and 2 tornadoes (so far) - one less than 2.5 miles from here. Severe t'storms warnings still up over a large area.

No sleep for grandpa tonight - weather watchtower duty

My first one here happened the first week I landed.
I was sitting in my pc chair in my 2nd story wooden shoe box appartment.

The half bottle of whiskey I consumed after nicely calmed my nerves.

A 5.0 apparently....

[lowlifecat]

depends where in canada... This particular area goes through around 150 earthquakes /year. Most are 2s and 3s with the odd 4s. The kind where you have to be flat on your back in a basement to feel.

There are 5-6s once every 10ish years (the last two where in lake erie area)

There are some big faults in the area (follows saint laurent river). The area north of here is still rebounding from the last ice age.

One thing that bugs me: right after the quake it was announced it had been a 5.5. Later it was revised to 5.7.

On the news they called it a 5.0 there is bloody 7000% difference between 5.0 and 5.7, where did it all go?!

My theory is that they felt it as a 5.0 in Toronto and because they are the center of the universe; it was a 5.0 earthquake.

[Brian Ellis]

7000%? Hardly!. It is a logarithmic scale. This means the essentially horizontal (destructive) movement increases by a linear factor of 10 for an increase of 1 on the scale. If you want it on 360° energy release, the difference between 5,0 and 5,7 is ~8.5x on a linear scale.
