ShakeAlert Earthquake Early Warning

Education and Training Materials

Over 143 million people live in an earthquake-prone region of the United States. The states of Washington, Oregon, and California face one-third of this earthquake hazard and risk. A moderate-to-large magnitude earthquake in dense population centers such as Los Angeles, San Francisco, Portland, or Seattle has the potential to cause severe damage which could threaten the national economy and its security. In light of these potential risks, the United States Geological Survey, in partnership with state emergency management agencies, geological surveys, and academic partners, developed and implemented the Advanced National Seismic Systems’ ShakeAlert® earthquake early warning system for the west coast of the United States.

IRIS and UNAVCO, in collaboration with the USGS and ShakeAlert® system partners at large, are developing a suite of educational activities and animations designed to inform and engage multiple audiences, from middle school students through senior citizens in many learning environments. The activities are bite-sized (5, 15, or 30-45 minute) demonstrations or student tasks tied to ‘Did You Know?’ questions to engage the learner, while the short animations (2-3 minutes long) present a variety of earthquake related subjects. Our educational resources aim to present factual information about earthquake hazards and explain why the west coast is earthquake-prone. We also address misconceptions about earthquakes, such as the relationship between an earthquake’s magnitude and its intensity.
