| | SEISMIC HAZARD ASSESSMENT, ONONDAGA COUNTY, NEW YORK |
 | | Onondaga County was selected for study because of the types of surficial materials deposited within the County during retreat of the Wisconsinan Ice Sheet, 13,000-10,000 years ago, and because of the large urban population in the greater Syracuse region. |
 | | The thesis by Steven J. Winkley, 1989, The Hydrogeology of Onondaga County, New York, Syracuse University, M.S. Thesis, 118p, was used in the compilation of the Surficial Geologic Map of Onondaga County. |
 | | The composite seismic hazard in Onondaga County represents an overlay of areas within the County that have Liquefaction values of Very High or High, Ground Shaking Amplification values of 4 or 5, and Landsliding values of 8, 9 or 10, when the surficial materials are either wet or dry. |
