These pictures of tornadoes are taken more than 100 years apart. There are a lot of things that changed over the course of the years that helped improve the quality of the more recent picture; more knowledge behind how to take a picture, better cameras and technology, and also more chances to get a picture of an active tornado because of the continued research on their patterns. You can even follow tornadoes and track them using your cell phone. The same scientific and technological improvements are true for safe rooms. We used to solely rely on going underground or into our linen closets if we wanted shelter from the storm, but now, thanks to science and continued research, there are bigger and better options when you’re looking for a way to safely ride out a tornado. At Tornado Alley Armor Safe Rooms, we take pride in the fact that our shelters have not only been built to be 100% FEMA compliant, but we are also members of the NSSA (National Storm Shelter Association.) This means that we have also successfully passed our impact testing performed at Texas Tech AND we have taken advantage of the advances in tornado safety and have been verified by third party engineers (for an unbiased review) that our shelters are strong enough to withstand an EF-5 tornado.
