Dr. Dennis Mileti’s PrepTalk, “Modernizing Public Warning Messaging,” presents research on how to design and disseminate alerts and warning information that encourages public action. He also emphasizes that “multiple dissemination channels for public disaster warnings yield quicker and more comprehensive audience penetration,” Mileti says. “One technology is insufficient because you need multiple technologies to reach different sub-populations in an at-risk audience.” He is the author of more than 100 publications.
