Did you feel it? Didja? Huh? Early-early Wednesday morning? Or have Oklahoma's little earthquakes become so common you sleep right through them?
Not me. I could probably get used to sleeping with a John Deere 9630 firing up in the next room every hour — if it fired up every hour. But let one little noise occur out of the ordinary and HAPPY BIRTHDAY, as Frosty the Snowman says when he comes alive: I am UP and at 'em.
So there I was, UP, heart racing, at 1:54:45 a.m. Wednesday, and at 'em by 2 a.m. sharp — online, looking to see if what I'd just heard and felt was an earthquake, after making passes through all the rooms to make sure all furniture and other items were in their places and all domestic livestock secure.
I know it was 1:54:45 a.m. thanks to the U.S. Geological Survey. The data on the quake wasn't posted by 2 a.m.; it does take time. But it was up in a few hours.
Add near immediate earthquake data to the wonders at our fingertips, which I know is old news — but I stumbled across something I hadn't noticed the last few times I went searching for info after a particular quakelet.
First, the details:
• Magnitude: 2.4.
• Date-Time: Wednesday, November 21, 2012 at 07:54:45 UTC (Coordinated Universal Time), 01:54:45 a.m. at epicenter.
• Location: 35.752°N, 97.494°W.
• Depth: 5 km (3.1 miles).
• Region: Oklahoma.
• 10 km (6 miles) N of Edmond, Oklahoma.
• 15 km (9 miles) SSW of Guthrie, Oklahoma.
• 27 km (16 miles) NNE of Warr Acres, Oklahoma.
• 28 km (17 miles) NNE of Bethany, Oklahoma.
Plus some other details about “surface wave magnitude” and the like.
But here's the really fun part: The “Did You Feel It” page at http://earthquake.usgs.gov/earthquakes/eventpage/dyfi/.
It lets you submit your own details:
What was your situation during the earthquake? (Inside a building, in my case). Select the option that best describes the structure you were in at the time. (Single-family home). Were you asleep? Did others nearby feel it? Shaking strength? Shaking duration (2 seconds, in my case). How did you react? (Excitement).
Was there any damage to the building? Options range from “No Damage” and “Hairline cracks in walls” to “Masonry fell from block or brick wall(s)” to “Separation of porch, balcony, or other addition from building” and “Building permanently shifted over foundation.”
In a nutshell: It sounded like an explosion a mile or two away. The sensation lasted just that long: the duration of a boom. I was surprised, actually, to learn it was an earthquake.
No shake, not much of a rattle, no roll. Just a boom. A real different kind of boom.
