Explore the fundamentals of seismology and Earth's internal structure in this 43-minute lecture. Delve into topics such as elastic rebound theory, megathrust faults, and the propagation of earthquake waves. Learn how to locate earthquakes, differentiate between body and surface waves, and understand methods for determining earthquake magnitude and intensity. Examine the destructive potential of earthquakes, including liquefaction and tsunamis, and investigate current approaches to earthquake prediction. Gain insights into Earth's interior layers through the study of seismic wave behavior, and discover how this knowledge contributes to our understanding of our planet's composition. Utilize resources from the USGS Earthquake Hazards Program and NOAA Tsunami Program to enhance your comprehension of these critical geological phenomena.
