While that may be the case in other places, the second siren in Joplin was to alert residents that there was a tornado on the ground. Twenty-seven minutes later, the sirens sounded again, but this time some residents didn’t know what to do, some even thought it indicated an all-clear. Prior to the touchdown of the 2011 tornado, the people of Joplin heard the sirens go off for a storm on the northern edge of the city that did not produce a tornado. This is special because no national standard currently exists for such a system. Joplin has also worked with neighboring communities to develop a regional activation policy for outdoor storm sirens. They’ve made these shelters available year-round with an automatic unlocking system that activates as soon as a tornado watch is issued. Not only can they accommodate the entire population of the school, but also all of the residents within quarter- to a half-mile radius around the school. The community rebuilt schools with storm shelters and added storm shelters to schools that weren’t even damaged. While the hospital was eventually torn down, construction on a new, stronger successor was completed in 2015. The people of Joplin took the damage of the 2011 tornado into account as they were rebuilding their community and made changes to their building code that improved tornado resistance. Not every building needs to be able to withstand an EF-5, but critical facilities like hospitals and 911 call centers must be designed to remain operational following these events so they can continue to serve their communities after the storm. We need to make a paradigm shift in how we consider tornadoes in the built environment. fatalities per year than hurricanes and earthquakes combined. Tornadoes are also more deadly, causing more U.S. It’s true that they are smaller events and impact less area than say, a hurricane or an earthquake, but tornadoes are much more common and significantly more intense than we have understood in the past. One hundred sixty-one lives lost, 3,000 residences heavily damaged or completely destroyed the devastation was overwhelming.ĭid you know that, with the exception of provisions governing the design of storm shelters, the word “tornado” isn’t even in our building codes? Is it any wonder that our buildings fail? We design for other hazards, but tornadoes haven’t been part of that calculation because they are perceived as being too rare, which is strange because we record over 1,200 of them annually. And I had never experienced the aftermath of an EF-5, so Joplin was a first. Only after that tornado, which damaged parts of Sedalia, Mo., had passed, were we able to get back on the road.Īs part of my work, I had seen the damage that tornadoes and other severe types of weather can cause, but you never really get used to it. We had to race to the small town of Marshall, Mo., where we ended up huddling alongside some students in the basement of the Missouri Valley College science building. Coincidentally, as my colleague Erica Kuligowski and I were driving to Joplin to get our first look at the 2011 tornado’s impact, we had a pretty harrowing run-in with an EF-2 tornado. Growing up in Dallas and going to school at Texas Tech in Lubbock, I’ve had a few close calls with tornadoes as well. Living in southeast Louisiana for nearly 20 years, my family and I had experienced many of these hurricanes directly, including some of the most infamous storms of the past few decades: Andrew, Katrina, Rita, Gustav, and Ike. As an engineering professor and director of the LSU Hurricane Center, I had conducted a number of investigations following tropical cyclones. I had come to NIST just three months earlier from Louisiana State University to lead R&D efforts under the National Windstorm Impact Reduction Program. I was among a small, but highly skilled team of engineers and a sociologist dispatched to the scene two days later to collect data on how well the buildings and emergency communications systems had performed during the storm. Over 3,000 of those residences were heavily damaged or completely destroyed. All told, the tornado damaged 553 business structures and nearly 7,500 residential structures. With losses approaching $3 billion, it was also the costliest tornado on record. It caused 161 fatalities and more than 1,000 injuries, making it the deadliest single tornado in the U.S. since we began keeping official records in 1950. The May 22, 2011, tornado in Joplin, Mo., rated an EF-5-the most powerful ranking-on the Enhanced Fujita tornado intensity scale.
