Yellowstone Hit By Swarm Of Earthquakes

Historical poster of Yellowstone from 1938By Howard Pankratz for the Denver Post:

Yellowstone National Park has been rattled by more than 250 earthquakes in the past two days following a period of 11 months of quiet seismic activity in the park.

The quakes have been gaining strength, with a 3.1 tremor recorded at 11:03 a.m. today. A 2.9 quake was recorded at 12:38 p.m.

Prof. Robert B. Smith, a geophysicist at the University of Utah and one of the leading experts on earthquake and volcanic activity at Yellowstone, said that the activity is a “notable swarm.”

“The swarm is located about 10 miles northwest of Old Faithful, Wyo., and nine miles southeast of West Yellowstone, Montana,” said Smith.

Jamie Farrell, a doctoral student in geophysics who works with Smith at the University of Utah, said that as of 3 p.m. today, 270 quakes have been recorded in the past two days.

Farrell said the quakes are occurring in an area about 5 miles from where the largest swarm of quakes was ever recorded in October 1985.

Quakes in the current swarm have ranged in magnitude of 0.5 to 3.1.

Farrell said there have been reports of at least one of the tremors being felt in the park, but he is expecting more reports as the earthquakes continue…

    There's no mention of the current theory that it was the 40 mile wide supervolcano under Yellowstone that wiped out the dinosaurs, rather than a comet impact. If you want to see how such an eruption might turn out for us, read Cormac McCarthy's THE ROAD.

      Another book I read recently described it as “the world turns gray and everything dies.”
