An Earthquake for the Holidays

In the doldrums between the Christmas and the New Years holidays the New Madrid seismic zone has decided to remind us that it is around by calling attention to itself.  This morning at about 8:20am a 2.6 magnitude earthquake occurred west of Millington, Tennessee. It occurred in the midst of stormy weather and did not attract much notice outside of our instrumentation.  For more information go to Millington Earthquake

204 years ago this week.

On Wednesday of this week the 204 years ago the first of the great New Madrid earthquakes occurred.  It would herald a burst of seismic activity in the central United States that would include 2 more major earthquakes and  change the face of the region for years to come.  These earthquakes are still being studied and discoveries are still being made about them. The earthquakes do not willingly give up their secrets and only by coaxing information from the past both geologic and historic can new information shed more light on the phenomena that would be felt across the North American continent all those years ago.  For more information about the earthquakes and their history go to New Madrid Comependium

An Earthquake in Michigan

Even though the focus of this blog is the New Madrid seismic zone sometimes events come to notice that would be of interest to the reader.  Occasionally earthquakes occur in the Central and Eastern United States that are not in seismic zone. One of these occurred in Michigan over the weekend. It was a magnitude 4.2 and was centered in southern Michigan.  Of note is the several state area in which the earthquake was experienced.  This was a phenomena noted with the New Madrid earthquakes which were felt for vast distances across the continent. For more information visit Michigan earthquake

Historically Michigan is not noted for earthquake activity. They occasionally occur there but are not common,   During the New Madrid earthquakes Detroit and the surrounding area was noted to have felt them.

Another weekend, another earthquake

It seems the New Madrid seismic zone has been active on a weekend basis in recent times.  While last weekend was mild and sunny inviting people outside to enjoy the spring an earthquake occurred near Ridgley, Tennessee. It occurred in the early evening of May 1st. For more information look at Ridgley earthquake.
