This site contains information about paleoseismology. In the world of earthquakes, 'ancient' translates to before the 20th century and before instruments were used to record earthquakes. The article takes a look at how paleoseismologists study the sediment around faults to help predict future earthquakes. It covers what faults are and the role they play in earthquakes, how paleoseismologists use sediment ... Full description.

In this exercise, learners will plot earthquake hypocenters along a cross-section in an attempt to 'image' a fault deep beneath the surface. The hypocenter data is from the aftershock sequence of the 1986 North Palm Springs, CA earthquake. This activity is suitable for learners who have a good understanding of high school algebra and geometry. This activity can be typically accomplished during a 50-minute ... Full description.

This site contains information about the general model geologists have developed to explain how most mountain ranges form. This model suggests that mountain building involves three stages, which are accumulation of sediments, an orogenic period of rock deformation and crustal uplift, and a period of crustal uplift caused by isostatic rebound and block-faulting. The later two stages of this model involve ... 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.

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.

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.

This teaching box is an online assemblage of related learning concepts that focus on teaching students about how and why earthquakes cause damage. These activities are presented as an inquiry exploration, in which students learn the importance of studying past earthquakes to predict what might happen in the future. The teaching box explores seismic waves, the predictability of earthquakes at specific ... Full description.

This lesson uses interactive diagrams of ground shaking from the 1906 San Francisco Earthquake to teach students about the mechanics involved in the rupture of a fault and the propagation of seismic waves as an earthquake progresses. They will understand that earthquakes begin at a point; that a long section of a fault can rupture during an earthquake; that the earth shakes in all different directions ... Full description.

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 classroom activity uses a cake to demonstrate geologic processes and introduce geologic terms. Students will learn how folds and faults occur, recognize the difference in behavior between brittle and ductile rocks, and attempt to predict structures likely to result from application of various forces to layered rocks. They will also attempt to interpret 'core samples' to determine subsurface rock ... Full description.
