A Century of Earthquakes

On April 18, 1906 a powerful earthquake shook San Francisco leading to fires that devastated the city. That earthquake brought seismology into the forefront as a science in the U.S. This poster outlines the lessons learned from the 1906 San Francisco earthquake and discusses much of the science we have learned from 100 years of large earthquakes since.


Keypoints:

  • The elastic rebound theory provides a model for the accumulation and sudden release of stress as an earthquake.
  • Over the past 100 years, the three largest earthquakes account for nearly half of the totoal seismic energy release of the planet.
  • "Great" earthquakes are generated by subduction zones becuase the fault geometry allows large sections of brittle crust to slip at once.

Between 2001 and 2011, more than 18,500 seismic events between Magnitudes 5 and 9.3 were recorded and located by the US Geological Survey. This list highlights some of these recent seismic events that are of special interest because they have caused notable geologic changes to our landscape or devastating destruction to our society.

Liquefaction is a process by which water-saturated sediment temporarily loses strength and acts as a fluid. This effect can be caused by earthquake shaking.

The Earth has 3 main layers based on chemical composition: crust, mantle, and core. Other layers are defined by physical characteristics due to pressure and temperature changes. This animation tells how the layers were discovered, what the layers are, and a bit about how the crust differs from the tectonic (lithospheric) plates, a distinction confused by many.
