How does ShakeAlert work and how can it be used?
ShakeAlert (www.shakealert.org) is an experimental earthquake early warning system that can give vital time to get to safety after an earthquake occurs. This animation demonstrates how ShakeAlert works by showing how P & S waves are used to locate and measure earthquakes, then send notice to your location about arrival times of potentially damaging waves. The 2014 M6 Napa earthquake showed how even a few seconds can be life saving. The animation also shows how ShakeAlert would work for a large M7.8 earthquake on the southern San Andreas fault.

The IRIS Earthquake Browser (IEB) is an interactive tool for exploring millions of seismic event epicenters (normally earthquakes) on a map of the world. Selections of up to 5000 events can also be viewed in 3D and freely rotated with the 3D Viewer companion tool.
jAmaSeis is a free, java-based program that allows users to obtain and display seismic data in real-time from either a local instrument or from remote stations.
Knowing precisely where an earthquake occurred is an important piece of scientific information. It can help seismologists identify and map seismic hazards. It is also a fundamental piece of information necessary for facilitating studies of Earth's internal structures. This fact sheet provides an overview of the S-P process to locate an earthquake.

Each station on the interactive map recorded an earthquake with a characteristic seismogram. Roll over the stations to see the epicenter triangulated. Touch buttons to watch movie of seismic waves, or touch "Walk-run" button to see wave travel can be demonstrated with a class.
The "moment magnitude" scale has replaced the Richter scale for large earthquakes. Scientists have developed far-more sensitive seismometers that, with faster computers, have enabled them to record & interpret a broader spectrum of seismic signals than was possible in the 1930's, when the Richter magnitude was developed. Find out what scientists learn from seismograms.
ShakeAlert (www.shakealert.org) is an experimental earthquake early warning system (EEW) being tested in the seismically vulnerable West Coast of the United States. This animation shows how ShakeAlert worked for the Napa earthquake, and how it could work for a large M7.8 hypothetical earthquake in Southern California.
This animation by UNAVCO shows us how an earthquake warning system uses existing seismic networks to detect moderate to large earthquakes. Computers, communications technology, and alarms are devised to notify the public while an earthquake is in progress.
