Haiti’s earthquake and the Richter scale

New activity!

On August 14th, Haiti was hit with a powerful 7.2 magnitude earthquake.

What does a 7.2 magnitude earthquake imply? What's a seismometer.  What is the amplitude of a seismograph and what does it mean?

Use our Richter scale activity to introduce your students to logarithmic Richter magnitudes.  Discuss linear versus exponential growth.  You might also use our graph of Richter magnitudes at Desmos.com.
