From 2011: Underground plume of Yellowstone supervolcano bigger than thought
The biggest Yellowstone earthquake in recent times occurred on August 17, 1959. It was a 7.3-magnitude quake that caused over 28 fatalities and left $11 million in damage to highways and timber. The slide blocked the flow of the Madison River resulting in the creation of Quake Lake. Effects of the earthquake were also felt in Idaho and Wyoming.
The 1959 quake was the strongest and deadliest earthquake to hit Montana since the 1935-36 Helena earthquakes left 4 people dead.
Bottom line: A 4.8-magnitude earthquake shook Yellowstone National Park on Sunday, March 30, 2014.
