Next thing we know they'll say the midwest got hit by a Magnitude 3 earthquake... oh wait.
Ever since Haiti then Chile this year, the media is gona report every tremor from a 3-4 (which is barely felt) to something actually serious like a 6.
Also look at the depth of some of the higher ones. A 2-3 near the surface isn't even noticeable, imagine what a 2-4 80 miles deep feels like... only the seismologist would know.
