Hazard preparedness at the family-, business-, and community-level is critical to building a resilient community capable of mitigating the worst of natural hazards events. Similarly, the duration of a volcanic event can be forecast through careful geodetic monitoring and modeling (Segall, 2013). Engineering geology is the application of geology to engineering study for the purpose of assuring that the geological factors regarding the location, design, construction, operation and maintenance of engineering works are recognized and accounted for. 2010. Geologic Hazards Mitigation is the application of geologic engineering principles to minimize or prevent the effects of naturally occurring geologic hazards. In the case of an earthquake, for example, a rapidly determined rupture model can be used to estimate the size of the tsunami (if any) as well as to forecast the size and location of large, potentially damaging aftershocks (Bock and Melgar, 2016). or which negatively impacts the productive capacity/sustainability of a population.
