According to USGS, this place is not safe for time being

Around 1,000 earthquakes have now been recorded  at Yellowstone volcano since January 

The popular national park is closing off areas to visitors because of "Elevated seismic activity" 

According to USGS, the geothermal activity that helps create some of the site's most notable features can also be a "recipe for trouble" by causing some roadways to melt

So far, the experts are not signaling for any disastrous event

Yellowstone National Park—which extends across Wyoming, Montana, and Idaho—sits atop a large, relatively young and active volcanic system  

This system features magma (subterranean molten rock) boiling and pressurized waters, and a variety of active faults

Though there is no immediate threat issued by the agency, they have cautioned people about it.
