Yellowstone quake swarm continues

After dropping off some, quakes increase again-

This time around, fortunately,  fewer folks are predicting doom. 😉

These swarms happen every year or so. With the development of the Internet, blogging, and the realization of the catastrophic potential of the Yellowstone supervolcano, news of these earthquake swarms began to spark alarm when they were reported.  In fact they have come and gone each time making little observable difference.

Large quakes are possible in and near the Park, but not common. The largest since seismology developed was in 1959. This 7.4 quake just northwest of West Yellowstone caused a huge landslide at the mouth of the Madison River Canyon. It dammed the river, buried a number of campers, and created what is now named Quake Lake. In total 35 people died. More information on that quake.

There have been a number of moderate quakes since, and one other large one, a 6.5 quake in 1975 centered near Norris Geyser Basin. None have resulted in any volcanic activity.

More than 1,200 tiny quakes hit Yellowstone Park, but jitters are few.  By Mead Gruver. Associated Press.
