Social media becomes a communicating channel during a natural disaster for detecting disaster events because people share their opinions, feelings, activity during the disaster through the Twitter. Twitter is not simply a platform for broadcasting information, but one of informational interaction. So, we use this platform for mining various disaster relevant tweets during a natural disaster.

This thesis examines various aspects of environmental economics. The first chapter estimates how individuals' beliefs about climate change are affected by local weather fluctuations. Climate change is a one-time uncertain event with no opportunities for learning; the belief updating process may not be fully Bayesian. Using unique survey data on beliefs about the occurrence of the effects of glo...

Natural disasters may be powerful and prominent mechanisms of direct and indirect hazardous material (hazmat) releases. Hazardous materials that are released as the result of a technologic malfunction precipitated by a natural event are referred to as natural-technologic or na-tech events. Na-tech events pose unique environmental and human hazards. Disaster-associated hazardous material release...

Recent natural disasters have brought forth the need for disaster preparedness, planning, and management. Hurricane Katrina demonstrated the usefulness of websites in dealing with a natural disaster. However, little is known about the necessary contents and structures of web-based information management for natural disaster preparation. In this paper, we focus on developing the ontology structu...

Recent empirical literature has found a negative relationship between income per capita and measures of risk from natural disaster, supportive of logic that higher incomes allow countries to mitigate disaster risk. We argue that behavioral changes at the micro level in response to increasing income (such as location choice and extent of costly abatement activity) may lead to a nonlinear relatio...
