Simulation Unveils Catastrophic Impact of Potential 7.7 Magnitude Earthquake in New Madrid Zone

Central United States, (The Lake Tribune) – A groundbreaking computer simulation has offered a stark visualization of the potential devastation a magnitude 7.7 earthquake could unleash in the central United States, particularly within the New Madrid Seismic Zone. This detailed simulation, incorporating a comprehensive geologic model of the central U.S., aims to depict the expected long-period ground shaking characteristic of a significant seismic event in this region.

The simulation illustrates the seismic waves emanating from the epicenter, vividly demonstrating the seismic energy’s concentration along the Reelfoot rift. This geologic feature significantly focuses ground shaking towards the northeast and southwest directions, affecting major areas including Paducah, Kentucky, and Little Rock, Arkansas. The simulation further highlights the Mississippi embayment’s role in amplifying and prolonging the seismic waves due to its relatively unconsolidated materials, with some locales experiencing 30 to 45 seconds of shaking.

The severity of this simulated earthquake’s impact is further detailed in a comprehensive 106-page report, which assesses the potential earthquake impact across the central USA. This document, available at CUSEC’s official website, outlines the anticipated hazards, inventory, and fragility assessments, alongside social impacts and direct economic losses. The extensive appendices include shaking maps, inventory data, fragility relationships, and detailed earthquake impact assessment methodology, offering an in-depth view of the potential state-level and regional damage, functionality loss, social impact, and direct economic losses.

This simulation and accompanying report underscore the critical need for preparedness and infrastructure resilience in the face of such a potentially catastrophic event. The New Madrid Seismic Zone, known for its historical quakes in the early 19th century, remains a significant concern for emergency management and disaster response planning in the central United States.
