This world map shows the major plates and plate boundaries, including such notables as the Mid-Atlantic Ridge, the San Andreas Fault, and the Java and Aleutian Trenches. The Pacific Ring of Fire is shown, including the Cascade Range. The location of major volcanoes is also depicted. A feature of this site is a black and white version that can be printed out for greater clarity. Full description.

In this activity, students plot earthquake hypocenters along a cross-section in an attempt to create an image of a fault deep beneath the surface. The hypocenters they will be using come from the aftershock sequence of the magnitude 5.6 North Palm Springs earthquake that occurred in 1986. The students will learn that accurate positioning of earthquake hypocenters can produce a rough image of a fault, ... Full description.

The prediction of earthquakes may be inexact, but it is vital, especially when large cities such as San Francisco or Los Angeles are threatened. The San Andreas Fault and two other faults, the Heyward and Calaveras faults, all have the potential to deliver a massive earthquake to the San Francisco Bay area. In this video segment, a seismologist explains the historical pattern of seismic activity in ... Full description.

In this activity a special layered cake is used to demonstrate folding and faulting of sedimentary layers. As a result of this activity students will understand the mechanisms by which folds and faults occur within the earth's crust, recognize the difference in behavior between brittle and ductile rocks, and be able to predict the structure likely to result from application of various forces to layered ...

This Classroom Connectors lesson plan teaches students the causes and effects of various forces upon the Earth. Specifically, students will learn about plate tectonics and the relationship between plates, faults, and earthquakes. This site provides goals, objectives, an outline, time needed, materials, activities, and closure ideas for the lesson. Classroom Connectors address content with an activity ... Full description.

"The Maximum Fault Hike" on this page has a guide for a hike in the Borah fault area (in Idaho), in a location with a number of horst and graben structures. Full description.

The Southern California Eathquake Center features a variety of links to information on recent and historic earthquakes and faults, as well as seismological data from analog and digital stations and instruments. Materials include an interactive map of southern California showing recent earthquake activity (last hour, last day, last week), a searchable catalog of data on earthquakes from 1932-present, ... Full description.

This virtual tour of the Hayward Fault extends from the city of Fremont, California towards the southern end of the fault. Many photos show evidence of offset and damage to natural and man-made features caused by creep along the fault. Full description.

This game has students simulate the propagation of S and P waves after an earthquake and use the lag between these to determine where in the simulation the earthquake occurred. Students stand in lines holding hands with those at the ends working as seismometers to record how long it takes P- and S-waves to reach them. On this Starting Point page, users can access information about the exercise's learning ... Full description.
