Earth Science - Earthquakes

Explore the fascinating world of earthquakes in this 35-minute lecture from Spahn's Science Lectures. Delve into the causes of earthquakes, focusing on convergent and transform plate boundaries. Learn about seismometers and various types of seismic waves, including P waves and surface waves. Discover how scientists determine the speed and size of seismic waves, calculate the distance to a quake, and use triangulation to pinpoint its location. Examine intensity scales and the Richter magnitude scale for measuring earthquake strength. Investigate the destructive power of earthquakes, including the phenomena of liquefaction and tsunamis. Enhance your understanding with supplementary videos on seismometers, seismic waves, liquefaction, and the 2011 Japan Tsunami.
