60 years of tornado activity, animated

Last Friday, an EF-4 tornado, the second-highest on the Enhanced Fujita scale, ripped through the St Lois Area. The twister caused significant damage to Lambert Airport and hundreds of homes. Miraculously, nobody was killed. According to the NOAA severe weather database, there have been 730 tornadoes of EF-4 or EF-5 scale between 1950 and 2010 causing 3,791 fatalities.

We took a look at this NOAA data in SpatialKey. Here's a timelapse of EF-4 and EF-5 events over 60 years.
