Earthquakes in Arizona. From Yuma in the southwest, to the Arizona Strip north of the Grand Canyon, to Flagstaff, to Douglas in the southeast corner of the State, earthquakes happen in Arizona. And because earthquakes do not respect political boundaries, earthquakes that occur in neighboring states – California, Nevada, Utah, Colorado and New Mexico – or Sonora, Mexico, may impact us here as well.

AZ Shakes is a resource for Arizona citizens, civil authorities, and researchers to learn about earthquakes and earth fissures in Arizona.
The mission of the Arizona Geological Survey (AZGS) is to inform, advise and assist the public in learning about the geological processes, materials, and landscapes of Arizona. AZ SHAKES is our ourtreach vehicle for delivering information on earthquake activity: the origin,nature magnitude, and historical and potential impact on Arizonan's and their property. Funding for AZ SHAKES provided by a grant from the Federal Emergency Management Agency (FEMA) through their National Earthquake Hazard Reduction Program (NEHRP).
In collaboration with our academic partners at Arizona State University, Northern Arizona University and the University of Arizona, AZGS operates the Arizona Integrated Seismic Network (AISN), a state-wide seismic monitoring network comprising eight broadband seismometers.
The AISN network is complemented by six analog seismometers operated by Arizona Earthquake Information Center at Northern Arizona University and by two additional broadband devices deployed by the Advanced Network Seismic System (ANSS).
