Abstract

The 1992 Northridge Earthquake in Los Angeles, California is one of the costliest natural disasters in the U.S. history, causing more than $22 billion (in 2001 dollars) property damage. Using the U.S. Geological Survey Landsat remote sensing images of Los Angeles area before (1989) and after (2001) the earthquake, this paper aims to investigate how the earthquake affected the urban land use changes in Los Angeles area, California. By comparing the supervised classification of remote sensing images at different time, the land use changes in the seismic risk areas of Los Angeles were identified. The results can be useful for governmental agencies such as emergency management and planning departments as well as private business sectors in the high seismic-risk zones.
