Write an analytical case study about a specific geological event that has occurred in an urban region. Topics might include specific landslides, areas of subsidence, sinkholes, earthquakes, or volcanoes. Geographic case studies detail a particular instance of something connected to a particular geography through literature research analyzed to illustrate a thesis or principle – in other words describe the where, what, when, who & why with the purpose of drawing out a “so what?” conclusion. Often in urban ecology the “so what” deals with a planning implication, best practice, or lessons learned from the event.
