Reducing seismic vulnerability in low to moderate risk areas

Abstract

Argues that, while the Commonwealth of Pennsylvania (USA) is found to be a low to moderate risk area in terms of seismic vulnerability, it is vulnerable to future episodes which could be quite threatening to a sizeable population. Degree of seismic vulnerability varies across the Commonwealth. Pursuant to assessing Pennsylvania’s earthquake preparedness, the Commonwealth’s various state agencies (n = 12) and the campuses comprising Pennsylvania’s State System of Higher Education (n = 14) were asked to complete a mail‐questionnaire which sought to determine their degree of earthquake experience, risk assessment activity, mitigation activity, and planning for response and recovery. A response rate of 78 per cent was attained. The experience, activity, and planning levels were found to be consistently low. These findings are consistent with research literature which describes the circumstances under which hazard reduction is likely to occur.
