Aha! I thought that I barely felt something at 8:14. I took note of the time in case a 20:14 event showed up.

At this point though, I'm so keen to suspect something might happen that I think that I'm psyching myself out and am just "feeling things"
all the time (vibrational mirages).

[Praedura]

A busy day such as today deserves another tune:

Home, home on the plains
Where seismic disturbances reign
Where often you hear, the earth rumbling so near
And the ground is not quiet all day

[Praedura]

Why do I have the feeling that late tonight, or rather early in the morning -- like around 3 or 4am -- there's going to be a big one?

Just feels like the build up to the main event...

It wouldn't shock me. These things aren't really letting up so the pressure is still there.

[dmoor82]

I know most of these smaller ones we really cant feel,but I swear about 3-4 times today I would see my blinds shake,so a larger quake wouldn't shock me!

Looks like that only pulls USGS records and not OGS ones, so that's not really an accurate source for the true number. I wouldn't trust it anyway.

We had an additional yesterday, so actually 4. Today we saw it tick back up to 7.

While the USGS may very true not be able to be as accurate or quick to update the latest Oklahoma earthquakes, it does unlike OGS, provide distances from towns earthquakes originated with link for more info, as well as the distance from the epicenter to Oklahoma City.

[Bunty]

OGN thinks the quakes have been occurring along a previously unknown fault line: Oklahoma earthquake surge reveals previously unknown fault line, state agency trying to connect dots

[venture]

The 19th had a few more quakes that previously reported...
April 19th - 16 quakes
April 20th - 2
April 21st - 5
Today (so far) - 4

Nearly all have been fairly weak. Only one that was at least 3.0.

Found this article about a possible major earthquake happening in the midwest. Don't know how credible it is, but it was an interesting read. The Big One » Local News » The Edmond Sun

Felt some kind of boom in Harrah a few minutes ago. Initially dismissed it as having the stereo up too loud but my wife came in to ask about it as it moved her chair and both our cats were freaked out. Can't seem to find any other mention of it other than somebody in KOCO's Livewire. Maybe feeling something from the Philippines quake?

Latest Quakes is a handy little app to keep up with what's shaking and where.

Not seeing anything on the helicorders online. So not sure what it was.

Finally found it reported at the USGS.

OGS seems to be down since May 31st...so wonder if they lost power at their facilities or something. Not easy finding these weak ones on helicorders from surrounding states.

It's just rehashed USGS data, we can get that from their page directly. The OGS site, with the local detection network, catches significantly more earthquakes that USGS misses.

From OGS:
"We experienced a computer failure and are working to recover our interactive earthquake catalog for Oklahoma. This information is provided while our interactive system is down. We are working to restore the functionality. Please be patient as we work to correct these issues."
