While IRIS did not have the Mineral Quake recorded I did find it elsewhere...
Takes a bit to load but hit play...
Now notice anything unusual?
Number of stations running through the middle of the country from North to South is amazing compared with the remainder except Southern Cali. Telling! Also, BL worked for years hardening bridges in the Meridian fault line areas.
Makes me wonder...
Supposed to be a “bunker-buster nuke” that knocked out the DC elite underground city, or something like that. The seismo did look interesting of the quake. Not sure about the rest of they nuke-theory.
