linkSome people have characterized the seasonal rise and fall of Yellowstone as being like breathing. During the summer there is a little pause in the overall trend of subsidence and sometimes even a short episode of slight uplift. The trend reverses in early winter.

During July, Yellowstone caught everyone’s attention with 1,000+ earthquakes located in seven distinct earthquake swarms. The largest swarm occurred beneath Yellowstone Lake and had 764 earthquakes, the largest of which was a Magnitude 3.6.

Yellowstone Volcano Observatory scientist-in-charge Mike Poland provides the YVO monthly update from the rim of Yellowstone’s Grand Canyon. The V-shaped gorge tells an amazing geologic story. About half a million years ago, a large rhyolite lava flow erupted. Over time, hot water and gases heated by the magma chamber rose through faults in the lava flow.

It's May, the snow is melting and the roads are mostly open, so it's time for geologists, geophysicist and geochemists to head into Yellowstone to start projects they have been planning for the last several months. Next week, a field team will deploy a temporary GPS network to help “densify” the network of continuous GPS stations already in place.

There are thousands of volcanic features distributed throughout the southwest United States, which are grouped together in volcanic fields. The Yellowstone Volcano Observatory monitors these volcanoes using a combination of techniques.

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, debunks the misconception that if Yellowstone were to erupt, it would be Armageddon. In fact, the most common form of eruptive activity at Yellowstone is a lava flow, and even those aren't that common. They happen only once every few tens of thousands of years.
