ShakeAlert: Earthquake Early Warning System for the West Coast

4min 35s Novice Spanish

Why is ShakeAlert® useful to me?

ShakeAlert® (www.ShakeAlert.org) is the U.S. Geological Survey (USGS) managed Earthquake Early Warning System for the West Coast of the United States. This animation demonstrates how the ShakeAlert System works starting with the detection of ground motion and moving data to a processing center where it is analyzed. If an earthquake fits a certain profile, a data package called a ShakeAlert Message is issued by the USGS and is made available to distribution partners who develop and deliver alerts that could prompt people to take a protective action such as Drop, Cover, and Hold On or trigger an automated action such as open a fire house door. Made in collaboration with the USGS and ShakeAlert partners in Washington, Oregon, and California.

Keypoints:

  • More than 143 million people in the United States are exposed to potentially damaging shaking due to earthquakes
  • With even a few seconds of warning, ShakeAlert can save lives and reduce injuries
  • ShakeAlert is not earthquake prediction, rather a ShakeAlert Message issued by the USGS indicates that an earthquake has begun and shaking is imminent.
  • Alert delivery will come by public and private means (internet, radio, television, cellular), including WEA alerts delivered by FEMA’s Integrated Public Alert and Warning System (IPAWS).
  • ShakeAlert is one tool in the earthquake resilience toolbox. Other tools include participating in long term preparedness efforts, practicing protective actions, and participating in exercises such as the Great ShakeOut.

We use exaggerated motion of a building (seismic station) to show how the ground moves during an earthquake, and why it is important to measure seismic waves using 3 components: vertical, N-S, and E-W. Before showing an actual distant earthquake, we break down the three axes of movement to clarify the 3 seismograms.

Earthquake intensity (what is felt during an earthquake at any given location) is often mistaken for earthquake magnitude (the instrumentally measured size of that earthquake). This animation describes the main factors that contribute to differing intensities using examples of earthquakes. Produced in collaboration with the U.S. Geological Survey.

When an earthquake occurs, seismic waves, including P and S waves carry energy away from the hypocenter in all directions. This video explores how the difference in the P and S waves results in staggered arrivals that, in turn, provides information about how far away the earthquake was from the seismograph.

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.

The epicenter is the map location on Earth’s surface, above where earthquake began. An earthquake actually begins inside the earth at the hypocenter. Learn more!

Animation Novice

Magnitude and intensity are both related to the size of an earthquake, but they each measure different aspects. One is measured using seismometers; the others is felt. Let's use a lightbulb as an analogy.

Related Fact-Sheets

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.

A seismograph is a device for measuring the movement of the earth, and consists of a ground-motion detection sensor, called a seismometer, coupled with a recording system. This fact sheet provides an overview of the basic components of a seismometer and physical science principles behind its operation.
