4.6 earthquake at Yellowstone: USGS deleted it

There have been a series of quakes at Yellowstone that have been collected as data on the recent quakes page, but then deleted. I don’t know why. Quake swarms are common at Yellowstone because it is the site of seismic activity after all, and also the site of a supervolcano that has magma on the move. But with the recent mega-swarm that caused so much panic last year, it behooves us to watch the location closely. But why were the quakes deleted from USGS lists? They are still captured on Intellicast maps, and are properly sourced to USGS. One of the quakes was a 4.6, which is an unusually large quake for the area.

Here are the links to check it out for yourself:

Look on the USGS list for Feb 11-12 quakes. USGS doesn’t have any, but Intellicast does- citing USGS. Look at the screen shot of the Lat-Long for Feb 12:

The red box indicates a 4.0+ sized quake on that date in that latitude and longitude. Now look at a screen shot of the same Lat-Long a day later. The 4.6 quake is gone, along with most of the others…

Also gone are most of the other quakes, and they are removed from the list on the Recent Quakes page, too. None for MT, UT or WY except for one 2.5 quake in Utah. File it under things that make me go “Hmmm.”
