This new StoryMap, 'Ten earthquakes that rattled Arizona', illustrates that Arizona has earthquakes and the potential for damaging, even life-threatening, earthquakes. Moreover, Arizona is subject to seismic activity in the neighboring states of California, Nevada, Utah and New Mexico, and Baja California and Sonora, Mexico.

To protect yourself from the ground shaking that accompanies moderate to large magnitude earthquakes, practice 'Drop, Cover and Hold On'. Follow the guidelines in Arizona is Earthquake Country to earthquake-proof your property or business.

Preparing for earthquakes could save you from injury and your home from damage in the event of a moderate to large magnitude earthquake.
