ST. LOUIS (AP) - A federal review of the 2011 Joplin tornado is calling for stronger building codes and more storm shelters in vulnerable areas.
The National Institute of Standards and Technology released its 492 page draft report Thursday at a Joplin news conference. The U.S. Department of Commerce agency calls the study the first to take a systematic look at how communities across the country can better prepare for twisters.
The study's recommendations include improved emergency communication systems to better warn residents of approaching danger. But institute officials emphasized that most of the power to make such changes rests with state and local governments and private businesses.
The May 2011 Joplin tornado destroyed 8,000 buildings and killed 161 people, making it the country's deadliest single tornado since records have been kept.
