The ubiquitous use of mobile devices and smartphones in the United States presents an interesting opportunity for application developers with respect to emergency management. Software engineers from the federal government to individuals have recognized the unique prospect of utilizing always-connected devices to assist in emergency notification, preparedness, and response. The federal government has instituted and ratified multiple acts and mandates with respect to mobile communications during a crisis such as the Commercial Mobile Alert System. Likewise, individual organizations and developers have created mobile applications that access weather alerts from the National Weather Service. Many of these applications utilize push notification architectures to notify users and stakeholders about impeding emergency situations. While most of these applications are geared towards a national audience, there are a few that are highly granular with a focus on the local community. This thesis presents a universal iOS application running on all iOS mobile devices: iPhone, iPad, iPad Mini, and iPod Touch for the Virginia Tech community. The application is highly granular with respect to emergency response guidance and notification by providing clear, concise, and supportive information to citizens during a crisis. Additionally, the application provides another medium of delivery for the Office of Emergency Management at Virginia Tech to potentially mitigate the extent of collateral damage and secondary incidents while saving lives. / Master of Science

Crises are spontaneous and highly variable events that lead to life threatening and urgent situations. As such, crisis and emergency notification systems need to be both flexible and highly optimized to quickly communicate to users. Implementing the fastest methods, however, is only half of the battle. The use of geospatial location is missing from alert systems utilized at university campuses across the United States. Our research included the design and implementation of a mobile application addition to our campus notification system. This addition is complete with optimizations including an increase in the speed of delivery, message differentiation to enhance message relevance to the user, and usability studies to enhance user trust and understanding. Another advantage is that our application performs all location data computations on the user device with no external storage to protect user location privacy. However, ensuring the adoption of a mobile application that requests location data permissions and relating privacy measures to users is not a trivial matter. We conducted a campus-wide survey and interviews to understand mobile device usage patterns and obtain opinions of a representative portion of the campus population. These findings guided the development of this mobile application and can provide valuable insights which may be helpful for future application releases. Our addition of a mobile application with geospatial location awareness will send users relevant alerts at speeds faster than those of the current campus notification system while still guarding user location privacy, increasing message relevance, and enhancing the probability of adoption and use. / Master of Science
