Cracked Plates & Tectonics

Cracked Plates & Tectonics Activity Source: Adapted with permission by Esri. In this activity, you’ll investigate dynamics in Earth’s crust that explain multiple Earth science phenomena. For the full activity, go to Materials A computer/projector with internet connection Take these “tech tips.” Measure: At the top of the map, click the Measure button. Hover and click the Distance button. Click continuously along what you want to measure. Double-click to finish. [Read More]

Earthquake on the Playground

Earthquake on the Playground Activity Source: Adapted with permission from L.W. Braile and S.J. Braile and the Incorporated Research Institutions for Seismology (IRIS). Push away from those paper seismograms and get outside to make your own earthquake waves! You’re going to learn about earthquake location kinesthetically. In the activity below, you will model how earthquake waves travel through the Earth at different speeds. You also will construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel-time curve). [Read More]

ShakeAlert Earthquake Early Warning

ShakeAlert Earthquake Early Warning Activity Source: U.S. Geological Survey, Adapted with permission. Have you ever felt an earthquake? What was it like? Where were you? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States. When an earthquake happens, seismic waves travel outward in all directions. Primary (P) waves travel faster than secondary (S) waves, which do most damage. But electronic information can be sent faster than P and S waves. [Read More]
