leeneia BS: Montana Earthquake July 2017 (22) RE: BS: Montana Earthquake July 2017 06 Jul 17

Here's the seismic info on this quake:

https://earthquake.usgs.gov/earthquakes/eventpage/us10009757#executive

Montana has a flat eastern part and a mountainous western part. The quake occurred about where the mountains begin, near Lincoln.

All the lingo at the beginning of 'Tectonic Setting' merely means that the movement along the quake was horizontal - two masses of land were sliding or jerking past one another, side by side.

It would not be unusual for shock waves which went east to be felt for hundreds of miles. East of the mountains, rock layers are relatively strong and unbroken, and waves can travel far.

In 2010, a 5.6 near OK City was felt in Chicago.
