Earth Changes ... in case you are asleep and waiting for an earthquake to wake you up ... Arkansas has been very active and growing in intensity. A 4.7-magnitude earthquake struck central Arkansas just after 11 pm. Sunday. More than seven hundred earthquakes have hit Arkansas since September. Chile: 6.0 magnitude February 28, 2011 This is just in from scientists! By studying seismographs from the (8.8) earthquake that hit Chile last February, earth scientists at the Georgia Institute of Technology have found a statistically significant increase of micro-earthquakes in central California in the first few hours after the main shock. The observation provides additional support that seismic waves from distant earthquakes could also trigger seismic events on the other side of the earth. |
