Indiana’s most recent weather tragedy

Chances are good that by now you know what happened last night in Indianapolis. According to news reports, a wind gust somewhere in the range of 60-70 miles per hour toppled a stage at the Indiana State Fair where the country group Sugarland was scheduled to perform. Five were killed and dozens were injured. For background, pictures, and a video from the Washington Post web site, click here.

It’s sad to see an occasion that could have brought so much joy and pleasure to so many end in this way. Too many lives have been cut short and too many others have been changed forever. We owe it to those who suffered such loss to ask what might be done to reduce such tragedies in the future.

Though Indiana’s governor referred to the high winds and the stage collapse as a fluke, the fact is that there undoubtedly will be repetitions of this heartbreak.  The Washington Post coverage cited similar events in Indiana’s history over recent years. Increasingly, meteorologists are thinking more about the dangers at such venues. [Interested?

Lightning was a particular concern during the 1996 Summer Olympics, which were held in Atlanta. Fortunately, no harm occurred.]

My friend Mike Smith, in his blog, Meteorological Musings, has already suggested that a gust front, clearly evident on radar and well-warned by his company AccuWeather to its clients, was the cause. Citing several similar weather-related incidents of this type in recent months, Mike suggested that it was time for those putting on outdoor events to reexamine their safety precautions.

As Mike pointed out, it may be impractical to design temporary stages and stands that can withstand such high wind speeds. He’s most likely right. Fabrication costs of sturdier facilities might be prohibitive. It might take much longer to erect such stronger structures. And such tragedies , though not flukes, are unlikely. The live shows are brief in duration, and highly localized. So are the weather extremes. Thus for any given performance, such a catastrophic concurrence of storm and show should be rare. However, given the thousands of such events that occur across the country every year, a disaster somewhere each year is almost inevitable.

Given that outdoor sporting events, live music, and other performances confer such great societal benefit, we don’t want to give them up. That leaves searching for mitigation measures in the social science of communicating risk and warning.

Perhaps, therefore event organizers could be more disciplined with respect to their warning and evacuation procedures. Organizers and local authorities could work toward better risk communication at such venues and better planning for evacuating and/or dispersing large crowds.

One suggestion that we’ve brought up in this blog several times might be useful here; an analog to the National Transportation Safety Board – a standing federal agency, as opposed to an ad-hoc group – for studying the causes of such calamities and recommending measures to reduce risk. Over time, such a group would very likely suggest a range of measures to improve communication that last mile – from governmental and private weather service providers to audiences in such venues.
