Major international seismic movement is occurring.
With the 8.3M (7.7M) event in the West Pacific, the Central America volcano activity, and the South America earthquake swarms…. across the board, an uptick in activity is showing.
Earthquake prone areas , and non-prone areas , BOTH need to be on watch.
Now we see a 4.9M earthquake strike the Western portion of the Yellowstone supervolcano magma chamber. A noteworthy event occurring along the Northwest edge of the craton (some agencies reporting a 5.0M).

44.644°N 114.251°W depth=5.0km (3.1mi)
This new 4.9M event is on top of the earthquake swarm over the past several weeks, and the PREVIOUS borderline 5.0M event 3 weeks ago (largest to occur in 40 years in the region).
Check this graphic from 12 days ago (March 30, 2014).
You can see the Yellowstone cluster spot , as well as the Oklahoma fracking swarm, and the Southern California event (which everyone already forgot about).
The areas along the edge of the craton need to be on watch for possible compensation movement in the near term.
With all the unrest currently happening internationally (and nationally), we can expect to see further movement along the edge of the craton in the near term.
Have an earthquake plan ready.
Don’t be scared, be prepared.
