Geohazard Assessment and Management - Geohazard, Weather, and External Force Mechanisms

This chapter is the second of four on the topic of geohazard assessment and management, focusing on geohazard, weather, and force mechanisms. The regulatory framework for geohazard assessment is introduced based primarily on US standard B31.8S and Canadian standard CSA Z662 as background for what constitutes a geohazard mechanism. The distinction between a hazardous geological/geotechnical condition, a geohazard trigger, and a geohazard event or process is described, and an overall philosophy for characterizing geohazards in a way that is compatible with the geohazard assessment methodology outlined in Chapter 14, and mitigation options outlined in Chapter 15, is introduced.
