To understand cultural and physical aspects of the earthquake, university students use geographic information system software to examine the characteristics of the affected human population (e.g., population density), damage to buildings, changes in the natural landscape (e.g., landslides) and ground shaking. Although the Northridge Earthquake is often described as an 'urban' earthquake, students learn that much of the strongly-shaken region was sparsely-populated, lessening the human impact."
