Tierney (1999, 216) says the field of Tierney (1999, 216) says the field of disaster studies has yet to develop a disaster studies has yet to develop a coherent theoretical perspective.”coherent theoretical perspective.”
Mileti (1999, 35) acknowledges that Mileti (1999, 35) acknowledges that “researchers have called for a broader “researchers have called for a broader view of the disaster problem and even for view of the disaster problem and even for a revolution in approach.” a revolution in approach.”
Interest in VulnerabilityInterest in Vulnerability
““Vulnerability is a greater determinant of disaster Vulnerability is a greater determinant of disaster than hazards themselves” (Alexander 2006, 2).than hazards themselves” (Alexander 2006, 2).
““Governments, disaster management agencies Governments, disaster management agencies and the community are increasingly accepting and the community are increasingly accepting that the proper focus of disaster management is that the proper focus of disaster management is not on the hazard agent in itself” (Buckle in not on the hazard agent in itself” (Buckle in Quarantelli 2005, 344).Quarantelli 2005, 344).

Comfort et. al. (2005, 43) “propose that Comfort et. al. (2005, 43) “propose that human vulnerability . . . becomes an human vulnerability . . . becomes an integral concern in the development and integral concern in the development and evaluation of disaster policies.”evaluation of disaster policies.”
Quarantelli (2005, 343-344) states “the Quarantelli (2005, 343-344) states “the recent shift in much of the literature from a recent shift in much of the literature from a primary focus on hazards to one of primary focus on hazards to one of vulnerability is a step in the right direction.” vulnerability is a step in the right direction.”
