Recently, we reported on a string of earthquakes that have hit the town of Manhattan, Montana.

For the past 20 years, there has not been a lot of seismic activity in Manhattan, but in just the past 30 days, there have been at least 7 earthquakes measuring 2.5 or higher on the Richter scale.

We caught up with Don Blakeman, a geophysicist with the USGS, in order to get a better understanding of what is going on under Manhattan.
