The quake at 12:10 appears to be one down to the NW of Fort Worth.

Just felt another one at 12:27am (6:27 UTC).
Probably less than 3.0 (but close). Brief, but definitely noticeable.

I wasn't dreaming last night, I had just quit watching tv at around midnight and turned over to go to sleep when the house shook. What was that, senility? I can accept that because obviously, it wasn't logged by OGS.

David,
The USGS shows one at 12:00 (0600 UTC), see below. What am I missing? I didn't mention this in my earlier post, but I thought it was in the high 2 or low 3 range.

Re: 2013 Oklahoma Earthquake Discussion
Obviously this can't be the cause and here's why: The colder it gets, the closer the water gets to turning to ice. Ice is obviously lighter than water (put an ice cube in a glass of water and watch it float.) Ergo, the water is lighter than it is in the summer so Lake Arcadia, itself, can't possibly be the cause of the most recent spate of earthquakes and aftershocks. Science Rules, Mythology Drools.
Anyone up for doing some random dunking of people and ducks out in that area to make sure no witches are behind this?

If you haven't read the comments on the News 9 story they are priceless.
And that article is a month old in case someone missed it.
Re: 2013 Oklahoma Earthquake Discussion
I read them. They were.
Another theory is that the Lake is covering an ancient Indian burial ground and the spirits are restless.
Not Native American Indians, but Sub-Continental Indians who were on a mysterious mission to the New World.

Re: 2013 Oklahoma Earthquake Discussion
Are you kidding me? Ice is lighter?
Re: 2013 Oklahoma Earthquake Discussion
Lighter . . . Less Dense . . . Whatever . . .
In any case, not the cause of the recent spate of earthquakes.
(now . . . if it were a spurt of earthquakes . . . on the other hand)

Re: 2013 Oklahoma Earthquake Discussion
Ice is less dense than water, so for a given volume of ice or water, the ice will have less mass.

Re: 2013 Oklahoma Earthquake Discussion
No kidding.
A lake that freezes loses no mass.

Re: 2013 Oklahoma Earthquake Discussion
Yeah, you're joking about a frozen lake being somehow lighter than the same lake, fully thawed?
David
Re: 2013 Oklahoma Earthquake Discussion
This is pretty basic stuff. Ice is less dense than water typically unless you are able to ensure there is no trapped air in the ice. How often does that happen? Now, you aren't going to lose water itself as it freezes, it is just going to expand and spread out.
We could probably assume that as a lake freezes, it is spreading the weight out over a greater area. As far as the lake having any impact on the earthquakes, who knows.

Re: 2013 Oklahoma Earthquake Discussion
The lake is not frozen, and it won't get cold enough to freeze, so that is not an option.
Participating Member
Re: 2013 Oklahoma Earthquake Discussion
I doubt it can be assumed that it would spread weight out over enough more area it would have any significance. Lakes freeze from the top down, so lateral movement outwards will be pretty small, especially near OKC were we rarely get more than an extremely thin layer of ice for a short period on any body of water of significance. Plus the short period that we might get a layer of ice also has the lowest amount of precipitation of the year, it seems like most years we are doing well to compensate for evaporation and what cities draw out of the lakes.
Re: 2013 Oklahoma Earthquake Discussion
The suggestion to check for witches (and ducks) should have been a tipoff.
But, speaking of ducks . . . I realize that the lake would never freeze all the way to the bottom. However, if a large enough flock of ducks or other waterfowl got their feet frozen in the top layer of ice, then flew away, taking the topical ice sheet with them, it might take enough of the stress off of the soil to minimize future lake effect earthquakes.

Re: 2013 Oklahoma Earthquake Discussion
lake arcadia was constructed in 1987. if the weight of the water is playing a role in seismic activity, you'd think that the frequency of seismic events would have increased not long after its construction instead of 25 years later. -M

Re: 2013 Oklahoma Earthquake Discussion
I don't know. I have a hard time believing the connection between the weight of Lake Arcadia and earthquakes happening 4 - 6 miles below the surface.
