Big Quake in Central US Would Displace Millions

21.01.2010
Theresa Jefferson and John Harrald, research faculty members at the Virginia Tech Center for Technology, Security, and Policy in the National Capital Region recently completed a Federal Emergency Management Agency (FEMA) funded research project to model the social impacts and disaster response requirements of a 7.7 magnitude catastrophic earthquake on the three segments of the New Madrid Seismic Zone.

The researchers, whose focus is response requirements and social impacts, found that such a disaster would result in 80,000 injuries and 3,500 fatalities. Their analysis also concluded that, due to the extensive damage to critical infrastructure and buildings, two million people would seek shelter.

Using damage and loss estimates produced by Amr S. Elnashai, director of the Mid America Earthquake Center, University of Illinois, the study principal investigator, and Lisa J. Cleveland, technical project manager with the earthquake center, the study focused on the impacts to vulnerable populations and the requirements necessary to support the 7.2 million people who would be directly impacted by such an event. Jefferson and Harrald have both academic and practical experience in crisis, disaster, and emergency management. They traveled extensively through the New Madrid Seismic Zone in connection with their research.

The New Madrid Seismic Zone is a 150-mile-long fault system spanning four states in the Central United States. Historic earthquakes in the region, such as the 1811–1812 earthquakes, are believed to have had magnitudes of approximately 8.0 if measured on the Richter scale. The geology in the Central United States based on soil liquefaction makes earthquake damage in that area much more widespread. There are approximately 12 million people in the high risk area; there are 44 million people in the entire New Madrid Seismic Zone region.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
