When plate tectonics causes part of the Earth's crust to compress, as in a zone of collision, or to extend, as in a zone of rifting, faults must form to help accomplish this task. While the deeper layers of rock, due to extreme heat and pressure, can fairly easily deform to accommodate the stretching of rifting or the compression of collision, the brittle rock of the uppermost crust must break and ...

This booklet features a collection of articles originally published for teachers by the San Francisco Chronicle. It presents some of the new understanding gained and scientific advances made in the century since the Great 1906 San Francisco Earthquake. Topics include lessons learned from the 1906 earthquake, the use of seismograms, recognizing active faults, and the use of trenches to investigate ... Full description.

In this activity, students create paper models to represent simple faults and illustrate some of the landforms associated with faulting of the Earth's crust. To make the models more realistic, some of the fault scarps are cut by gullies and are eroded in ways indicative of an arid landscape. All of the paper models show displacement on the fault by the use of arrows and by the offset of a marker bed ... Full description.

Since large fault ruptures require the build-up of a great deal of stress, many years pass between repeated surface ruptures on a single fault. The average time between such ruptures, known as the recurrence interval of that fault, is a useful measurement for assessing both the slip rate of the fault and the risk the fault presents. This activity contains three exercises. In the first, students study ... Full description.

This activity has two parts: the first part will demonstrate the weaknesses of simple fault models (like block diagrams) in depicting the process of fault rupture accurately; and the second part is centered around a fairly simple animation of rupture propagation, seen by an oblique map view, that attempts to show more accurately what we should envision when we think about fault rupture. This activity ... Full description.

This National Park Service (NPS) site provides links to geology field notes providing information about National Parks, National Monuments, and National Recreation Areas that have to do with plate tectonics. The site also has illustrations and descriptions of different plate boundaries. The parks are divided into categories depending on which type of plate boundary they are located on. This includes ...

This activity is designed to familiarize the learner with the concepts of strike and dip, to make further studies of faults and fault models easier. It also introduces learners to a few key elements of seismology, which will be seen again later in much greater detail. Knowledge of how to solve basic trigonometric equations is needed for this activity. To describe a fault plane in simple terms, geologists ... Full description.

This article describes the occurrence of listric normal faults (those which gradually flatten out with depth) in the continental shelf offshore Oregon and Washington, as seen in seismic reflection profiles. There is also a discussion of the faulting mechanics, the timing of uplift on the continental shelf, and the separation of compressional and extensional tectonic regimes on the lower and upper ...

Any single method for measuring the slip rate of a fault is subject to substantial errors, both in the accuracy of the method itself and in the interpretation of the results. Adding to the difficulty of reaching agreement between methods is the fact that the properties of faults (including slip rate) can change over time, or along the length of a fault. This exercise shows how different approaches ... Full description.

In this exercise, students will study the three types of faults, investigate the association between faults and earthquakes, and examine the relationship between earthquakes and plate tectonics. There is a set of animations that illustrate the types of seismic waves, an exercise in which students determine the location of an earthquake epicenter using arrival times of P and S waves, and an exercise ...
