Measuring Earthquakes

The video tutorial explains how seismic waves from earthquakes are detected using seismographs, which produce seismograms to help scientists determine earthquake details. It introduces the Richter scale as a method to measure earthquake strength, noting that each increase of 1.0 on the scale represents a tenfold increase in wave amplitude. The tutorial also compares the magnitudes of the 1964 Alaska earthquake and the 1989 Loma Prieta earthquake to illustrate the scale's application.
