I live in Edmond, OK and at 11:11 an absolutely massive earthquake compared to what normally happens here hit and shook the house for a minute or so.
On Reddit, it seems like OKC, Tulsa, Shawnee, and Norman folks felt the same powerful quake at the same time and are convinced that it originated near them.
USGS silent.
Anyone know what it could be? DUMBs?
When the USGS site blocks it, it is apparently under orders of the Military, so I think you nailed it. It's a D.U.M.B. or tunnel system explosion. What did Raspberry Shake say? I think they have an entry level free product. They often record what the USGS omits, and I'm not the only one saying that Gene Decode says that all the time:
