Arizona's Hidden Earthquake Risk Despite Desert Location
Science of seismic proportions | ASU News
Arizona’s deserts might not be situated on a tectonic plate boundary where geographical activity can cause earthquakes, but that doesn’t make the state immune from the disturbance of tremors.It has been 139 years since Arizona’s strongest recorded earthquake on the Pitaycachi fault struck in 1887. The 7.5 magnitude event, known as the Sonoran Earthquake, took place near the southeastern Arizona-Mexico border.
Arizona experiences seismic activity despite lacking tectonic plate boundaries, with the state's strongest recorded earthquake occurring 139 years ago. The 1887 Sonoran Earthquake, a 7.5 magnitude event near the Arizona-Mexico border, remains Arizona's most powerful tremor on record. Scientists warn the state remains vulnerable to future seismic disturbances.
