Middle schoolers learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas...

Students learn what causes earthquakes, how we measure and locate them, and their effects and consequences.

This series of three articles (links) give basic information, describe the different causes of tsunamis, warning systems, past tsunamis and the evidence and destruction left by these waves. Animations are provided that illustrate...

This outstanding website provides an excellent variety of hands-on earthquake activities to help you understand what causes earthquakes.

A 260-page unit of activities on earthquakes. Covers what they are, their cause, why and where they occur, their impact on the Earth, how they are measured, and safety and survival. Includes worksheets and has a glossary at the end.

The U.S. Geological Survey sponsors this site about the history of earthquakes in the United States as well as information about how earthquakes are detected and measured.

This website is a resource for learning about earthquakes. Java animation at this site helps you visually understand the causes of earthquakes.

Learn about earthquakes and how they are measured. Follow up with some activities that help to enhance your learning.

See how seismic waves propagate outwards, as wave fronts, in all directions following an earthquake.

The information on tsunamis provided at this site is part of the Burke Museum's online exhibition on earthquakes and geology. Prevention is discussed, along with famous tsunamis in history.

Looking for the epicenter of an earthquake and measuring the magnitude of waves are goals for young scholars in this lesson plan for intermediate to middle school students. Young scholars get to analyze the P and S waves.

[Free Registration/Login may be required to access all resource tools.] The signs scientists might see prior to an earthquake occurring.

Discussion of liquefaction and landslides which are two of the many effects of earthquakes.

The USGS provides an extensive section of information about tsunamis. The items presented are the basics of tsunamis regarding the Great San Francisco earthquake of April 18, 1906, tsunamis in the U.S. Pacific Northwest, and the 1998...

This resource describes the two different types of seismic waves and how they travel through the earth, offers diagrams of the waves, their speeds, and how seismograms are used to locate earthquakes.

Basic definitions and characteristics of the different wave types, diagrams, and speeds of the waves. Has links to information on seismology, earthquakes, and plate tectonics.

A video and a short multiple-choice quiz on earthquakes, how they form, how they are measured, and the ways they can change the surface of the Earth.

Earthquakes can often hit unexpectedly. This article reveals some of the intricacies of these natural disasters and what signs serve as indicators to alert seismologists.

An overview of measuring earthquake magnitude.

USGS provides the definition of a fault, the basics of earthquakes, the theory of plate tectonics, location of plates and earthquakes, and embedded links to related material.

[Free Registration/Login may be required to access all resource tools.] What a longitudinal wave is, its compressions and rarefactions and what a P wave is.

A quick, introductory lesson about how earthquakes happen, and what impact these natural events have on life.

Discover why earthquakes happen, how we measure them, and why they only happen on Earth.

Here's a project for studying compression waves in different soil types. It uses a homemade wave tank for solids, with a frequency generator, amplifier, and loudspeaker as the vibration source. There are lots of interesting possibilities...
