Section Materials
Visions of Earth, by AGI
A four-DVD set on interactions in Earth systems.
Seismograms for 2005 October 8, by USGS
This USGS page contains seismograms from more than 25 stations around the world that recorded the waves from the October 8, 2005 Pakistan earthquake.
Latest Earthquakes, by
USGS
Using KML Files for Google Earth display real-time earthquakes in Google
Earth. Google Earth is an interactive, 3D viewer that uses USGS elevation
data and a variety of public and private imagery sources, allowing the user
to seamlessly zoom from a global scale down to less than a meter in many
urban areas. To display the latest earthquakes, download one of the KML
files on the above site and open it in Google Earth. You and your students
will be fascinated by what you discover!
Earthquake Center Homepage, by
USGS
This is the homepage to a world of information from the USGS on Earthquakes.
It has recent information and past information, with links to animations,
maps, etc. Great site to explore!

Description of the scale currently used in the US. Includes a good explanation of the difference between intensity and magnitude.
"Seismometers, Seismographs, and Seismograms", by USGS Cascades Volcano Observatory
Learn about seismometers, seismographs and seismograms.
Visions of Earth, by AGI
82 High-definition animations showing a variety of Earth and space system processes.
How a Seismograph Works, by SERC
A Flash animation by W.W. Norton that first shows the arrival of seismic waves to a seismograph. Except for the immobile seismograph mass (heavy weight with pen) which does not move due to inertia, everything else shakes. This includes the horizontal rotating drum upon which seismic waves will be recorded. The animation can be paused and rewound to show the arrival sequence of P, S, and surface waves.
