An earthquake shook northeast Oklahoma early Monday afternoon.

The preliminary estimate of the quake lists it as a 4.5 on the Richter Scale.

The tremblor is believed to have been centered near Crescent, Oklahoma, roughly 3.2 kilometers below the surface and occurred at 1:12 p.m. Central Daylight Time.

KRMG has heard from people as far away as Wichita, Kansas who also felt the shaking.

It shook the building and rattled a few nerves at the KRMG studios near E. 71st Street and South Yale Avenue.

It's apparently the second quake of approximately 4.0 or better to hit the area Monday.

The earlier quake hit about 12 minutes earlier, also near Crescent, Oklahoma.

That one is listed as a 4.0 on the Richter Scale, and is believed to have occurred roughly 5.6 kilometers below the surface.

Crescent is northwest of Guthrie, in Logan County.

We are awaiting additional information from the Oklahoma and US Geological agencies.

So far, there are no reports of damage or injuries.
