Earthquake in Northern Ohio?

[DocCincy]

Just felt our whole office building shake here in Northern Ohio. Lasted about 10 seconds. Anyone else feel anything??

[cleveland gop]

I was in my car driving and didn’t feel a thing. My cousins in Akron felt it though. Now the ‘86 quake, that is a different story

[fanfan]

It looks like one of our hot spots blew it's top today.

[DollyCali]

thanks to all for their informative posts.

in Northfield OH, i am not sure we could feel one. I was chipping wood for a few hours .. mucher/chipper & my whole body was “shaking”

Another this to follow & wonder .. get, what if....

[Quix]

INDEED IT DOES.

THX THX.

[SunkenCiv]

Thanks fanfan and hennie pennie. I felt nothin'.

Tremors in Eastern Canada are rare but widely felt due to the rock under the ground here. They say this quake, like most, was caused by the earth rebounding after the glaciers of the last ice age retreated. Apparenty we get a lot of tremors from that, mostly 2.0 or less.

That’s why Mexico City was devasted. The entire city is a landfill on a lake and it completely liquidated during their bigh quake about 30 years ago.

Probably others. The oil and gas under Lake Erie and Southwestern Ontario and the salt dome under Lake Huron must lend themselves to a fair bit of seizmic activity.

Google “New Madrid Earthquake”. Apologies for delayed response — been driving since I made my last post and just got to where I have wireless access...

[gleeaikin]

The New Madrid quake was actually a series of quakes in 1811 and 1812. Three of them were over 8, many were over 7. Fortunately, there was not much population there then. Very bad if it happened now. Twenty thousand were killed in an earthquake in Caracas, Venezuela in 1812.

Thanks for the link fanfan...boy, what a day!

Perhaps. It might also be seen as a relatively innocent relief of pressure too. Of course a release of pressure in one area, could increase pressure at another location on the fault too.

What I noticed was that this quake was thirty miles off the New Madrid fault line. It may or may not actually have been a New Madrid quake. It may have been something moving perpendicular to the New Madrid fault zone. It’s widespread nature may shoot that down. I just don’t know.

Look, I’m expressing my theory based on living in a quake zone for most of my life, and watching how things developed on the fault lines I observed. Don’t take these as if they were comments by an expert geological insider.

[DoughtyOne]

It would seem so. Generally there are anywhere from tens to hundreds of smaller quakes after a moderate quake.

After the large quake just over the border into Mexico from California a few months back, there were hundreds of aftershocks in the first 24 hours, many of them 4.0 to 5.0 or greater.

30 miles is very close to fault of that magnitude.

[DoughtyOne]

Thirty miles does sound close. Still, if it’s not the New Madrid fault then New Madrid pressure relief or build-up would be affected differently.

If it was the New Madrid fault, it could be seen as relieving pressure in the region, possibly a good thing. If it’s a secondary fault, I believe it could only be seen as adding pressure to the New Madrid fault, not a good thing.

We have a number of known fault lines in California, and we’re learning of new ones all the time. Although some of them are within ten to twenty miles of the San Andreas fault, they still aren’t considered to be a part of it, and when they go off, they aren’t considered to be quakes involving the San Andreas, even though they may be affecting it.

I remember the earthquake in 1986 because it was the same day as Judy Resnik’s funeral in, Akron. After the earthquake I called a local radio station to see if anyone else was reporting an earthquake. The DJ told me that it wasn’t an earthquake, it was the jets flying over for Judy Resnik’s funeral. I told the DJ something along the lines of - “hey, I grew up in San Diego and I KNOW that was an earthquake.”

Turned out I was right. :-)

...boy, what a day!

You can say that again. ;-)

Cyman, this native Californian who's been through a zillion earthquakes (had one the other day, that one that moved San Diego something like 31 inches, that only got a casual glance at swaying hanging pots from my husband and me) and all of the major ones of the last three or four decades, was sitting here giggling at your comment:

"In the Imperial Valley California we use 5.5’s to stir our coffee in the am."

THAT SAID ... a 5.5 is pretty respectable. You folks over there in the East who felt it, don't let anyone tell you it was a candy-ass quake. It was big enough to make one get the picture fast: a human being is about as significant as a bug on this Earthly plane when nature's sh*t hits the fan. Nature calls the environmental shots, not us.

And Cyman, is Imperial Valley rock strata? I don't know. I do know that there are plenty of areas in California that get shook like jello in a decent quake. The Chino Hills quake, for example. That was a pretty ho-hum quake, yet it rocked the bejeebers out of places on flatter ground.

Ya just never know. What you do figure out is that everything, and I mean everything, that happens on this planet is temporary.

I live in ottawa.
I’ve experience two quakes in the last ten years I will remember. This one and another one maybe six or seven years ago. The first one was like an oncoming freight train in the dead of winter. You could actually hear it coming. Very unnerving feeling. Kind of like an animal I could sense something was wrong and something was coming. This 2nd one had no sound, but it seemed to be stronger and last longer.
It was a real shake and bake. Bizarre feeling of dread just waiting for it to end. Good thing canadians don’t live in straw huts. Everything up here built very very solid. Only old buildings seem susceptible. But these quakes are minor and happen infrequently unlike the pending doom facing good ole california.

[Finny]

Can you remember, for how long did you hear it coming, that rumble?

"Like an oncoming freight train ..." is a great description. I was in the Northridge Quake in the early 90s, about 25 miles from the epicenter. It hit in the wee hours, something like 4 a.m. I sleep so soundly my husband jokes that Patton's Third Army could go through our backyard and I'd sleep through it.

But the Northridge quake -- I awoke with a start, and there was a sensation of about 500 freight trains heading straight for us! I think it was only for a split second, but I'm certain that I was awake before our apartment started jolting us as around if it was God's martini shaker.

In retrospect, I figure the rumbling must have been horrific because the quake was rippling through about 100 square miles of solid cityscape and that rumbling of all those millions structures must have made a hell of a lot of noise (part of a 3-level concrete parking structure just a mile or two from us away collapsed -- can you imagine how much noise that made?).

When it hit our place (the top floor of a four-story apartment complex) the noise was terrifying. I remember bounding up the hall to our predesignated structural "safe" spot and feeling the floor wildly swaying left to right under my feet, like those fun-house floors at the carnivals.

What was WEIRD was that immediately afterward, for the first ten minutes or so I guess, as I walked around in a semi-coherent daze, scared gutless, I could see everything, as if the lights were on. I could see where my clothes were in the bedroom, pants to pull on, as we definitely weren't going back to bed! I puzzled for days as to when the electricity went out, then. After the quake? That long after the quake? And we didn't even have an overhead light in the bedroom, just bedside lamps, but I could see things as if it was daylight.

Husband had the same experience while methodically going around the place before the next big aftershock (count on 'em) to take glass-fronted and heavy-framed pictures off the wall. We talked about it later: we functioned as if the lights were on, and only later stopped to think, "But it was like 4 or 5 in the morning." Neither of us remember having to use a flashlight.

I finally concluded that all the adrenalin pumping in us must have triggered some extreme defense mechanism where our eyes dilated to the point we were like cats. It's the only thing I can think of.
