11.1 What Earthquakes Are

In this section you will find materials that support the implementation of 11.1: What Earthquakes Are. Use the navigation below to find the materials.

Section Materials


Resources

Visions of Earth, by AGI
A four-DVD set on interactions in Earth systems.

Theoretical P-Wave Travel Times, by USGS
This page from the USGS displays the predicted travel times of the P-Waves originating from the 6.7 magnitude earthquake that struck near Puako, HI on October 15th, 2006. There is a table of data as well as the map visualization.

15 Largest Earthquakes in the US, by USGS Earthquake Hazards Program
There are two lists on this page: the top 15 earthquakes in the United States and the top 15 earthquakes in the contiguous United States. The reason for the lists is that eleven of the fifteen happened either in Alaska or Hawaii.

Faults and Earthquakes, by USGS Geology in the Parks
Check out diagrams for a normal, reverse, and strike-slip faults.

Seismic Waves, by University of Nevada Seismology Lab
Overview of seismic deformation and the different types of seismic waves. Also covers how seismic waves are measured and how their measurement can be used to determine where earthquakes originate.

What Is Seismology and What Are Seismic Waves?, by UPSeis from Michigan Technological University
A bit more indepth, this site reviews not only P and S waves, but also Love waves and Rayleigh waves.

Incorporated Research Institutions for Seismology (IRIS)
In addition to a number of well-conceived teaching resources, this site has the real-time Seismic Monitor, where students can track various magnitudes of earthquakes happening from today through the past five years.

Did You Feel It?, by USGS
Anyone who experiences earthquake tremors can report this to the USGS through the site. Reported information is available in several formats and students can access archived information to track earthquake activity over the years.

Animations

Visions of Earth, by AGI
82 High-definition animations showing a variety of Earth and space system processes.

Southern California ShakeOut, by USGS
These compelling earthquake simulations show ground movement and wave propagation as an earthquake rupture propagates along the San Andreas Fault. These simulations are from the Great Southern California ShakeOut earthquake drill conducted in 2008. The animations capture the shaking at length scales larger than about 300 ft (100 m) and provide detailed animations of the shaking for this scenario earthquake. Several different views are available. The files are QuickTime and are available in three different resolutions.

Aftershock, by The Southern California Earthquake Center
This is a very good resource for teaching materials on earthquakes. It includes a simulation of what happens after an earthquake occurs.
