AGHP Webinar

Wednesday, October 1 | 1:00 - 2:00 pm ET | Online

Florida is well known around the world for its karst landscape and sinkholes. Like hurricanes, sinkholes are natural hazards that pose a risk to the state. Unlike hurricanes, you can’t see sinkholes coming. As such, the Florida Geological Survey has conducted extensive data collection and research on sinkholes in order to educate the public about sinkholes and provide tools supporting mitigation. This webinar will educate you on Florida’s karst landscape, the types of sinkholes present, and the problems they can cause. Finally, we will discuss the research and tools produced by the Florida Geological Survey to help mitigate the effects of sinkholes.
