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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
