Using social media data has several advantages over traditional means of data collection to understand multiple phases of disaster management. Previously, methodologies, such as phone calls, direct observations, or personal interviews, were commonly practiced by disaster responders and damage evaluators to gain situational awareness and investigate impacted populations. A typical social survey at the city level demands years of dedicated investment of resources to be successful [9]. Even with the research at rudimentary level, social media data has presented interesting snapshots about human society at a macro scale with agility that could only be dreamed of by traditional surveys [13]. Moreover, the timing of transitions between various disaster phases is usually unknown. The four disaster management phases do not always occur in isolation or in this precise order. Often phases of the cycle overlap and the length of each phase greatly depends on the severity of the disaster [14]. Social media data can provide “real-time” information for the emergency managers to understand the transitions and make effective decisions through multiple phases of disaster management.
