From the article: 
"

“Swarms in Yellowstone are a common occurrence. On average, Yellowstone sees around 1,500-2,000 earthquakes per year. Of those, 40 to 50 percent occur as part of earthquake swarms.  This swarm is larger than the average swarm we record but this is a normal thing to happen in Yellowstone (and other volcanic regions throughout the world).”

He says they are not seeing an “volcanic signatures” that would indicate an eruption could take place. “This looks to be a ‘tectonic’ swarm in that these earthquakes are due to slip on small faults/fractures in the crust.  There doesn’t look to be any evidence at this point that these earthquakes are related to the movement of magma in the subsurface.

"Having said that, we will continue to monitor this swarm just in case we start seeing those things.

“When a volcano starts ‘acting up’ prior to an eruption, one of the typical signs is increased seismicity.  However, it is usually just one of the signs of an impending eruption. Other signs include, large changes in surface deformation, changes to the hydrothermal system and changes in gas output.  We monitor for all these things at Yellowstone. Typically if we see just one of these things, it doesn’t necessarily mean there is an eruption coming. If we start to see changes in all these things, then a red flag may be raised.”

This story has been updated to include quotes from Jacob Lowenstern and Jamie Farrell."
