New Madrid Fault
March 12, 2011 by staff
New Madrid Fault, After magnitude 8.9 earthquakes struck Japan on Friday, many Missouri residents are wondering if the new Madrid fault line, which crosses the southeast corner of the state, could show similar activity.
University of Missouri geology professor Dr. Mian Liu studies the line New Madrid fault. He first explains how the earthquake in Japan has nothing to do with the state of Missouri.
“It happened so far. It’s a totally different system of land, a different process. It is therefore not increase or decrease the risk that we have here in Missouri, “he said.
The last earthquake along the New Madrid happened in the early 1800s. The fault model shows an earthquake every 400 to 500 years, which could produce another event over the next two centuries. However, studies by Dr. Liu could be New Madrid is finished with the reactions.
The fault lies in the middle of a tectonic plate much more. Active fault lines are continuous ground deformation, where the energy of the earth in place. However, the new line Madrid could be increasingly less dangerous.
“We found no significant deformation in our reviews of New Madrid. It makes some scientists suspect may be stopped New Madrid,” he said.
Dr. Liu compares the situation to a similar one in northern China. He studied another fault line in the middle of Asia. He found, in the last 2000 years, the earthquakes ranged from the fault zone of the fault zone and never occurred twice in the same place. He thinks maybe Missouri following the same pattern.
“If this is the pattern of how things work in other continents, then we have reason to suspect that perhaps the next major earthquake in the central U.S. will move somewhere else rather than the New Madrid seismic zone. ”
