Cleveland, Ohio -- Experts say Ohio seems to be increasingly prone to earthquakes.
A 3.1 magnitude quake hit Tuesday and there have been 25 earthquakes of magnitude 2.0 or higher over the past two years. That's equal to the number the five years before that.
And there have been about as many such quakes in Ohio so far this decade as in the previous 30 years.
Mike Hansen, coordinator of the Ohio Seismic Network, says Ohio is going through a period of increased seismic activity. He says that's especially true for northeast Ohio and Lake Erie.
Geologists say Ohio might be especially active because of a combination of a few ancient collisions.
The first was probably 800 million years ago, when land masses the size of continents came together, causing mountain ranges and fault lines.

Comment: Increased frequency of earthquakes, and only the blandest of explanations from the "experts".
"Nothing to see here! Move along! Earthquakes are 3 times more common now because of something that happened 800 million years ago."
Sheesh!
