According to Timothy Manning, Deputy Administrator for Protection and National Preparedness at the Department of Homeland Security's (DHS) Federal Emergency Management Agency (FEMA). Since the September 2001 terrorist attacks, significant and measurable strides have taken place to improve preparedness for the hazards faced by all levels of government and all segments of society (DHS, 2012).

             FEMA is now part of the DHS's Emergency Preparedness and Response Directorate. FEMA is tasked with advising on building codes and flood plain management; teaching people how to get through a disaster; helping equip local and state emergency preparedness teams; coordinating the federal response to a disaster; making disaster assistance available to states, communities, businesses, and individuals; training emergency managers; supporting the nation's fire service; and administering the national flood and crime insurance programs.Listed below are some of the improvements that have taken place post 9/11 (DHS, 2012).

             In the four years between 2006 and 2010, the proportion of states and urban areas that were confident in the effectiveness of their emergency operations plans increased from 40 percent to more than 75 percent; commercial radio broadcasters, in partnership with FEMA, today can deliver public warning messages to more than 84 percent of the U.S. population, up from 67 percent in 2009. By the end of 2013, coverage is expected to expand to more than 90 percent of the population;.

             Since 2001, federal, state and local governments have built a network of specialized teams capable of interdicting and disrupting a variety of imminent threats. That network includes 1,100 Hazardous Materials Response Teams, 5,400 SWAT teams, and 469 FBI-trained and accredited bomb squads;.

             Prior to the Sept. 11 terrorist attacks, major population centers in many parts of the country lacked structural collapse and urban search and rescue capabilities.
