Alabama tornado outbreak second deadliest, according to monitoring team

March 22nd, 2012 by Susan Smith

A monitoring team from the Marshal Space Flight Center is monitoring the disastrous tornado outbreak in Alabama on April 27, 2011, that greatly impacted the economy of the state.

This image is of ASTER NDVI for the NWS Tuscaloosa tornado swath on top of NASS CropScape data layer. The graph shows the difference in NDVI in and outside of the tornado path.

On record, the tornado outbreak was the second deadliest tornado outbreak in the U.S. When considering the agricultural and value-added activities such as food and timber processing, farm inputs, manufacturing, transportation, and retail sales, the dollar value of Alabama agribusiness annually exceeds $40 billion (NASS). This research aims to examine how the timber and agriculture damage affected the state economy of Alabama. The research harnesses NASA ASTER and MODIS data along with NASS ground verified surveys to analyze the scale of change in land use/land cover, vegetation, soil profiles, topography and other surface features post April 27 tornado attack in order to examine the effectiveness of the recovery strategies at a local level.
