Course Description

Overview

Explore the fascinating world of earthquakes and Earth's interior in this 51-minute geology lecture. Delve into the mechanics of faults, seismic wave propagation, and earthquake measurement techniques. Learn about different types of faults, seismographs, and how to locate earthquake epicenters. Examine the various scales used to measure earthquake magnitude and intensity, and discover the challenges of earthquake prediction. Investigate seismic gaps, paleoseismology, and the paths seismic waves follow through Earth's layered structure. Gain insights into plate tectonics, earthquake destruction, and the study of meteorites as they relate to understanding our planet's interior.

Syllabus

Earthquakes and Earth's Interior
Faults - Movements that produce earthquakes are usually associated with large fractures in Earth's crust called faults Most of the motion along faults can be explained by plate tectonics
Slippage along Faults
Types of Faults There are three major types of
How do Faults cause Earthquakes?
Principle of the Seismograph
Seismology: Seismographs
Seismology: Body Wave Motion
Seismology: Seismic Waves - Surface waves (Two Types: Love and Rayleigh Waves) + Travel along outer part of Earth
Locating the Source of Earthquakes
The Epicenter Is Located Using Three or More Seismographs
Determining the Size of Earthquakes
Seismic Intensity Map, Loma Prieta, 1989
Measuring the Size of Earthquakes • Magnitude scales
Earthquake Destruction
Can Earthquakes Be Predicted?
Seismic Gaps: Tools for Forecasting
Paleoseismology: The Study of Prehistoric
Review: Body Waves versus Surface Waves
Paths that Seismic Waves Follow through Earth
