This paper shows how Noticed Witness Data can ease the challenges of information triage in disaster response efforts. Recently, disaster management has seen a revolution in data collection. Because information and communication are cornerstones in preventing risky behaviors, advanced technologies uses to the reduction of seismic risk by providing to the crowdsourcing management. Real-time determination and reporting of all disaster and emergency incidents that we may encounter in our daily lives are crucial. That is especially true of the natural hazard types common in the geographic location of our country and of terrorist incidents. Systematic reporting of disaster and emergency situations is required to promote safety of life and property and to rapidly and reliably determine the scope and degree of the disaster. Because each disaster and emergency incident has spatial data properties, those incidents are represented as real objects in the geographic information system (GIS) solutions, and databases aimed at modeling the relationships between those objects are developed. Crowdsourcing management is used effectively in such quick, assessment-oriented studies. Crowdsourcing is not a new phenomenon; it has been used in the past in many cases for collecting users’ participations [1] In this study, an new damage estimation method in the earthquake has investigated by using of Web Geographic Information System (GIS) Technologies and Mobile Application with witnesses participation. The method is based on earthquake witnesses, who are the first to feel an earthquake, and therefore the first informed that an event is happening. The real-time information and data is collected in connection with to the populations affected by earthquakes. The research aims to minimize the damage and losses caused by disasters and emergency incidents, to provide public information services, and to contribute to the literature concerning the utilization of crowdsourcing.
