Between December 26, 2008 and January 8, 2009 in the YellowstoneLake area, there were 813 distinct earthquakes ranging in magnitude up to 3.9. There was another swarm that was larger – but it was back in 1985.
No property damage occurred. Take a look, it’s pretty interesting.It’s a good explanation of what’s going on – and we’re not to worry!
It’s still perfectly safe to visit YellowstoneNational Park & the Jackson Hole area.
