Brett Smith for redOrbit.com - Your Universe Online Folks living near the Mississippi River where Arkansas, Tennessee, Missouri and Kentucky converge should expect to see a low-flying, red-and-white Cessna today. Do not be alarmed, U.S. Geological Survey officials announced. The region, known as the New Madrid seismic zone, is of particular interest to geologists and the federal agency is using low-level flights, being performed by specially trained pilots, to detect subtle local...

Seismology tip sheet: New Madrid seismic zone, Japan quake, earthquake triggering and more among topics to be discussed This tip sheet highlights presentations at the upcoming international meeting of SSA, which is an international scientific society devoted to the advancement of seismology and its applications in understanding and mitigating earthquake hazards and in imaging the structure of the Earth. These summaries reflect submitted abstracts and the actual presentations will include...

2000 years of Chinese records shows migrating mid-continent earthquakes This December marks the bicentennial of the New Madrid earthquakes of 1811-12, which are the biggest earthquakes known to have occurred in the central U.S. Now, based on the earthquake record in China, a University of Missouri researcher says that mid-continent earthquakes tend to move among fault systems, so the next big earthquake in the central U.S. may actually occur someplace else other than along the New Madrid...

Understanding earthquakes minimizes loss of life and property University of Oklahoma researchers are working with Chinese colleagues to better understand intraplate earthquakes"”those occurring far from a tectonic plate boundary"”in an effort to minimize the loss of life and property in both China and Oklahoma. China holds the record for the deadliest earthquake with 830,000 casualties, even though the event occurred far from a tectonic plate boundary. In recent months, a U.S....

Most earthquakes occur along fault lines, which form boundaries between two tectonic plates. As the relative speed of the plates around a fault increases, is there a corresponding increase in the number of earthquakes produced along the fault? According to this study published in the December issue of BSSA, the answer depends upon the type of tectonic boundary. On certain types of boundary, the efficiency of earthquake production actually depends on the fault slip rate. Seismic hazard...

Although the fault zones beneath the Mississippi River Valley have produced some of the country's largest modern earthquakes east of the Rocky Mountains, scientists acknowledge they don't yet fully understand the Midwestern seismic zone that caused Friday's earthquake in southern Illinois.However, what they do know is rather unsettling.  The Midwest region is covered with old structures not built to withstand seismic activity.  And, when earthquakes do happen, they are felt at...

The first direct evidence of how and when tectonic plates move into the deepest reaches of the Earth is published in Nature today. Scientists hope their description of how plates collide with one sliding below the other into the rocky mantle could potentially improve their ability to assess earthquake risks. The UK and Swiss team found that, contrary to common scientific predictions, dense plates tend to be held in the upper mantle, while younger and lighter plates sink more readily into the...
