As earthquakes go, those at Yellowstone are pretty weak, and they reflect underground movement of magma, as opposed to plate movement, or land movement caused by underground magma movement.
Yellowstone National Park Hit By Magnitude 4.8 Earthquake

March 30 (Reuters) - Yellowstone National Park, which sits atop one of the world’s largest super-volcanoes, was struck on Sunday by a magnitude 4.8 earthquake, the biggest recorded there since February 1980, but no damage or injuries were immediately reported.
The tremor, a relatively light event by seismic standards, struck the northwest corner of the park and capped a flurry of smaller quakes at Yellowstone since Thursday, geologists at the University of Utah Seismograph Stations said in a statement. ...”

About 1,000 to 3,000 earthquakes strike Yellowstone each year, according to the Yellowstone Volcano Observatory, a research partnership of the park, the University of Utah and the U.S. Geological Survey.
The ancient super-volcano, or caldera, that lies beneath the surface of the park was discovered by scientists in recent years to be 2.5 times larger than previously thought, measured at 30 miles (48 km) wide, according to the park.
Sunday’s quake occurred near the center of an area of ground uplift that geologists have been tracking for several months, University of Utah seismologists said. Elevated seismic activity was also found in the area during a previous period of uplift from 1996 to 2003.
The recent spike in earthquake activity at Yellowstone is linked to the uplift, which in turn is caused by the upward movement of molten rock beneath the Earth’s crust, according to the U.S. Geological Survey.
Fortunately, there was no indication that the recent seismic activity signaled an impending eruption of the Yellowstone Caldera, scientists said. ...”

I'm not. It's going to go.
But, geologically speaking, the event is only a few ticks of the clock away.
In terms of human experience and frame of reference, that's probably another 2000 years from now, minimum.
As is the next major asteroid hit.
:) ...or should I say :0!
My Troop and I spent a week at Camp Meriwether in Oregon. Learned about John Colter, and Colter’s hell.
He was something else, John Colter. They were made of sterner stuff.
As a youngin’, I tried to aspire to Colter. He was definitely one of my first, non-athletic, heroes!

This webpage talks about the effect a large eruption the size of Yellowstone would do to the Earth’s climate.
Interesting article until it stated that even the cooling results of a magnitude 8 volcano would not stop global warming!
Even the mention of ‘glowball warming’ causes me to have much reduced faith in everything else in the article.
I saw that, too. I should have warned ya!
The AGW crap has really been a great Big Lie indoctrination of the Left.
When Mt. Pinatubo erupted back in 1991 in the Philippines it dropped the global temperature about one degree Fahrenheit for a year. Just think of what Yellowstone would do!
