Natural Hazards Test Bank

Course

Introduction

Natural Hazards explores the scientific principles and real-world impacts of geologic and atmospheric hazards such as earthquakes, volcanoes, tsunamis, hurricanes, floods, landslides, and wildfires. The course examines the causes and mechanisms of these events, their environmental and societal effects, and the methods used to assess risk, predict occurrences, and mitigate their impact on human communities. Through case studies and hands-on activities, students learn how hazard assessment and emergency management strategies contribute to public safety and sustainable development.
