I think it's just called Supervolcano (but it may have a subtitle, like "disaster at Yellowstone" or some such). It's a BBC movie and is supposed to be shown over here on a regular US cable channel, like Discovery, not on BBC America....

Googled "bbc supervolcano" and the second hit was the BBC blurb on the show:

Supervolcano

The beauty of America's Yellowstone National Park masks one of the rarest and most destructive forces on Earth - a supervolcano.

A new two-part BBC factual drama asks: 'What if Yellowstone erupted?'

Parts 1 & 2: 13-14 March, 9pm BBC One

No listing on network or timing for US broadcast there.

Here's another hit from that same google search:

Yellowstone Supervolcano Drama on BBC this Month

which has more detail on the program.  It does state that it is co-produced by BBC and Discovery (among others) so I guess that means it's going to be on Discovery.

Thanks for the information! I'll keep an eye out.

...so I guess that means it's going to be on Discovery.

Beware of specials on Discovery. Right after the Indian Ocean Tsunami, The Discovery Channel ran a special several times that made irresponsible sensational claims about a volcano, Cumbre Vieja, on the island of La Palma in the Canary Islands off the coase of North Africa. In the special, they claimed that a side of the volcano could suffer a landslide which would spur a "mega-tsunami" that would deluge the whole East Coast of America. They were claiming the wave from such a tsunami could reach 300 feet at Miami, FL. They said it would dwarf the earthquake-generated Indian Ocean tsunami. This is absolute hogwash, according to all but a handful of geologists. The "Tsunami Society" was very critical of such claims. Yet Discovery ran with it over and over because it was sensationalized by the Indian Ocean tsunami. They needlessly scared a lot of people to get a few more ratings points. I no longer trust the Discovey Channel.
