Earthquakes Rock Oklahoma
Over the past couple of years, earthquake frequency and strength have risen in Oklahoma, a state most wouldn't equate with such tectonic activity. In fact, 2010/11 has been the most active so far, and just days ago the Sooner State saw its strongest yet--at nearly 6 points. I've blogged about this increased activity before and postulated whether it could be a precursor to another event along the New Madrid fault, a potentially dangerous scenario for those cities along the Mississippi River. But in Oklahoma, the Meers Fault has been active as well, and one wonders if it isn't becoming something with which Oklahomans will have to deal with in the future. Records of seismic activity in Oklahoma are less than 100 years old, so in a geological sense we're quite ignorant as to what might be "normal" for this region. Is this a new threat emerging or a cyclical activity that will subside with time? We'll have to wait and see. Check out the Earthquake tag below to read more.
