Magnitude 3.5 earthquake in the New Madrid Seismic Zone

Well this morning the New Madrid seismic  zone had a 3.5 earthquake.  It caused a stir here as our instruments detected it quite clearly. Also it was felt in the Tiptonville/New Madrid area. It happened at a time when people are more likely to feel it that being the quiet time of the morning. For more information visit3.5 magnitude earthquake.

The other earthquake news was the 5.6 magnitude Oklahoma earthquake that occurred Saturday morning. This was felt across a broad area of the Central United States including the Memphis area.  More information can be found at Oklahoma earthquake.

In the case of both quakes if you did feel it, please fill out the did you feel it form as this data is important to help in calculations of effects vs. magnitude of earthquakes in the Central and Eastern United States. Every bit of data helps.

A Few more Earthquakes

Over the last week New Madrid has been a bit more busy.  On the 6th and 7th of August there were a couple of earthquakes with the initial magnitudes being 2.3. These were later revised and had differing magnitudes . The first was 4 miles southwest of Caruthersville, Missouri with a magnitude of 2.3 and the second on August 7th was 4 miles northwest of Tiptonville, Tennessee with a magnitude of 2.5. On August 9th there was a magnitude 2.8,  5 miles west-northwest  of  East Prairie, Missouri. Thats not counting the magnitude 1.5 earthquake of August 7th that was 3 miles southwest of Caruthersville, Missouri.

As a note the magnitude 2.8 earthquake generated a few "did you feel it reports" in contrast to the July 4th earthquake.  This was probably due to the lack of fireworks in August to distract people from feeling the earthquake.

And finally not to be outdone by the New Madrid seismic zone there was an earthquake nearby in the Wasbash seismic zone in Southern Illinois 8 miles west-southwest of Albion, Illinois, with a magnitude of 2.4 on August 8th.

A Shake on the 4th of July

A few minutes before the end of the 4th of July an 3. 0 earthquake happened near Carruthersville, Missouri.  The earthquake  should have been felt by many in the area except for one factor. That is with all the fireworks going off it would be hard for anyone near the epicenter to tell the difference. During the American Civil War the same effect occurred for reports of earthquakes. Due to the concussions and noise of the fighting people did not notice or were indifferent to earthquakes. Reporting of earthquakes in the eastern United States does not pick up until after the war was concluded.

For more information on the earthquake please go to this link4th of July Earthquake.  Also if you felt it please report it to the Did You Feel It? link in the website. These reports are important to scientists who measure the effects of earthquakes in the New Madrid seismic zone and surrounding areas.

A couple of earthquakes

Last night and early this morning we had a couple of earthquakes. One was inside the New Madrid seismic zone and the other was in Alabama. The first one occurred last night at about 10 o'clock near Carruthersville Missouri, the magnitude was 2.5 and its depth was 10 kilometers.  For further information go to Carruthersville earthquake

The other earthquake happened this morning in Alabama. This one was not located in the New Madrid seismic zone but in the zone of intermittent regional seismicity. Alabama has occasional earthquakes and this is one of them.  For more information  go to Alabama earthquake

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
