In this activity, students use online animations of foreshocks in an attempt to decide whether or not they think the earthquakes that occurred on the last day (day 90) of the animations are foreshocks of a large earthquake (mainshock) that will occur on the following day. Full description.

This is the earthquake information page of the Natural Resources Canada, Geologic Survey of Canada, Sidney Subdivision. It contains links to recent and historic earthquakes and earthquake hazards. The seismographs and seismic data sites contain data for the past twenty four hours from selected locations and activity for the past hour for fifty locations. There are two other sections. One has information ... Full description.

This activity has students compare maps of plate tectonics with population density maps and to analyze what these maps imply about the relationship between population and seismic hazards. Students will read about and discuss the theory of plate tectonics, map the regions of the United States that are most susceptible to earthquakes and those that have volcanoes, and list the states that lie on plate ... Full description.

This unit provides an introduction for younger students on earthquakes, volcanoes, and how they are related. Topics include evidence of continental drift, types of plate boundaries, types of seismic waves, and how to calculate the distance to the epicenter of an earthquake. There is also information on how earthquake magnitude and intensity are measured, and how seismic waves can reveal the Earth's ... Full description.

This web page is a set of well-illustrated online notes from an introductory course (SLU EAS-A193) taught by the author. The notes cover the following topics: An Introduction to Earthquakes and Earthquake Hazards; What is Science?; Critical Thinking; Early Earthquake Observations; Faults and Faulting; Waves, Seismograms, and Seismometers; Earth's Origin and Composition; An Introduction to Plate Tectonics; ... Full description.

This earthquake unit was designed to be used with a college course in physical geography. From this module, students learn the location of areas in the United States with the greatest potential for earthquake shaking and the hazards presented by earthquakes. They also learn how geological conditions and building construction affect the amount of destruction during an earthquake. Seismographs and the ... Full description.

In this activity, students plot the locations of earthquakes on a world map for a week or more, and examine their distribution in relationship to Earth's plate boundaries. It includes a bilingual vocabulary list (Spanish/English). Full description.

This resource is part of the Science Education Gateway (SEGway) project, funded by NASA, which is a national consortium of scientists, museums, and educators working together to bring the latest science to students, teachers, and the general public. In this lesson, students use the Internet to research data on earthquakes and volcanoes and plot locations to determine plate boundaries. Extensions include ... Full description.

This on-line text offers chapters on: a Basic Description of Earthquake History, Where Earthquakes Occur, How Earthquakes Happen, Measuring Earthquakes, Volcanoes and Earthquakes, and Predicting Earthquakes. Originally published as a book in a series of general interest publications prepared by the U.S. Geological Survey. Some figures in this version of "Earthquakes", however, have been changed for ... Full description.

This brief tutorial and activity will provide younger students with some idea how earthquakes occur. The text explains how strain builds up along a fault until the rock breaks, releasing energy in the form of seismic waves. This concept is reinforced by a simple experiment in which the students break a foam rubber block in half and then try to slide the broken halves past each other. Full description.
