doesn't stop Emergency Officials from gearing up. Getting the word out has gotten much easier for mostplaces including right here at WDBJ7. WDB7's DavidKaplan shows us why and how.Emergency Management officialssay the most famous example of the power of socialmedia and mobilealerts happened in the Louisa County Earthquake of 2011.The story goes that people read aboutthe earthquake on twitter before they felt the tremors. It is amazing, fromthe social media site, from thetechnology standpoint. Billy Ferguson hasdone emergency management inFranklin County for33 years. He remembers very well life before the digital age. You go door to door, you would put the PAsystem on a police car and you'd say it out and you'd walk down thestreet with a bullhorn. I just can't see us doing that today.The biggest addition to most Emergency Manager's arsenals;reverse 9-1-1. Ferguson is one of five people in Franklin County whocan literally draw a circle or any other shape over ageographical area, see when police are close, and in case ofemergency, call every landline in that area. It's kind of like an insurance policy; glad you have it, we don'twant to use it, if we get by every yearand use it it'll be fine for us. Whether it's robo-calls, text alerts or social media from local emergencyservices or even WDBJ7, getting theword out to as many people as possible,just in case, is most important. An added challenge in rural communities. We're trying every way we can to get itout there. We still know there'sfolks who fall through the cracks andanything we can do to improve that, wecertainly want to do it. the cracks and anything we can doto improve that, we certainly want to do it. Those reverse 9-1-1 calls that localities are depending moreand more on apply only to landlines unless people sign up their cell phones. That's one thing emergency officials say can help fewer people slip throughthe cracks. Go to your area'semergency management page to sign up if it does usereverse 9-1-1.
