Scientists have determined that the earthquakes preceding volcanic eruptions are different than those that precede earthquakes. Discover the sounds and wave patterns produced by the three different types of volcanic seismic activities.

Poke around the world map to examine where there is earthquake activity.

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

This university consortium provides on-going, current information on seismic activity happening all over the world. Of special interest is the Seismic Monitor. Open this page to a full screen to monitor global earthquake activity in real...

Students learn about how engineers design and build shake tables to test the ability of buildings to withstand the various types of seismic waves generated by earthquakes. Just like engineers, students design and build shake tables to...

Learn how seismic tomography imaging helps scientists understand the formation of the Earth's interior.

A live, real-time data global map of all current earthquake activity.

Students use U.S. Geological Survey real-time, real-world, seismic data from around the planet to identify where earthquakes occur and look for trends in earthquake activity.

Interactive website, with videos, aerial views, photographs, and slideshows, documents the actions taken to replace and stabilize portions of the San Francisco-Oakland Bay Bridge against future seismic activity.

This outstanding multimedia site documents the earthquake and related events that took place on October 17, 1989 in the San Francisco Bay Area.

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.

This site includes all things shaky--earthquakes that is. Observe real-time data regarding seismic activity all over the world. Other modules include information about history's great quakes, earthquake basics and how to recover from...

A report on the discovery that solar flares produce seismic activity. Site also includes movies, images, background information, and other media reports concerning solar flares.

The basics of earthquake science including factual information about how and why they happen. Also includes some hands-on activities and experiments for students.

Multi-activity activity where students will work with data from a seismic wave model in a GIS (geographic information system) program. They will examine maps, select data, and produce graphs to explore variations in seismic wave...

In this unit you can learn about the deformation of rocks, magmatism, plutonism and seismic waves. It has 16 interactive activities.

In addition to exploring the inside of the earth, this unit will explore the consequences on the dynamics of the outer layers; it will deepen the knowledge of plate tectonics and the movement of the plates in the past. It includes 16...

Students learn how engineers characterize earthquakes through seismic data. Acting as engineers, they use real-world seismograph data to locate earthquake epicenters via triangulation and determine earthquake magnitudes.

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

This activity allows students to observe a small-scale model of liquefaction, a hazard associated with strong-magnitude earthquakes. The sand, water, and ping pong ball(s) represent the composites of soil: sediment, water, and air,...
