Lecture 15 (Friday, February 22): Earthquakes and Seismology II

Brief outline of this lecture:
Controls on earthquake impact
Measuring earthquakes
Damage from Earthquakes

Main points of this lecture:
Local geology influences the impact of earthquakes.
Regional geology and the distribution of faults influences the impact of earthquakes.
The Richter scale measures the magnitude of earthquakes, or the energy released.
The Richter scale is less than ideal, especially in characterizing large earthquakes.
The Mercalli scale measure the intensity of earthquakes in terms of local effects and damage.
Earthquake damage comes in many ways
