Earthquake Geology and Seismic Hazard Assessment

Earthquakes are among the most powerful natural phenomena on Earth, posing significant risks to communities and infrastructure. Understanding the geological footprint of past earthquakes is essential for predicting future events and minimizing their impact. This course introduces you to the foundational principles of earthquake geology and demonstrates how geological data is translated into practical seismic hazard assessments. You will start by exploring the core concepts of plate tectonics, active faults, and structural geology. From there, you will learn how to identify active tectonic landforms and read the sedimentary records of past earthquakes. By the end of this course, you will understand how geologists map fault lines, calculate slip rates, and contribute crucial data to modern seismic hazard models. What you'll learn: - Understand the foundational concepts of tectonic geomorphology and active faulting. - Identify and map active faults using satellite imagery, digital elevation models, and field observations. - Analyze paleoseismic trench data to reconstruct the history of past earthquake events. - Calculate fault slip rates and earthquake recurrence intervals to estimate future seismic activity. - Apply geological data to modern probabilistic and deterministic seismic hazard assessment frameworks. - Evaluate the role of earthquake geology in urban planning, engineering design, and risk mitigation. The course begins with essential geological terminology and structural concepts before guiding you through practical field methods, trenching techniques, and modern hazard evaluation workflows. It is designed for beginners, students of earth sciences, civil engineers, and anyone interested in natural hazards, with no prior geology background required.
