At 10:01 a.m. on 27 April 2019, Duncan, Arizona and environs were rocked by an ML 3.6 earthquake. AZGS Research Geoscientist J.Y. Ben-Horin filed this preliminary report.
On the evening of 1 Nov. 2015, residents of the Phoenix Metro area were rudely awakened when a magnitude 4.1 earthquake shook the valley. According to the Arizona Republic, and numerous other Phoenix-based media outlets, people across the Valley of the Sun felt a sharp jolt followed by several seconds of ground shaking. There were no reports of injuries or damage. That modest earthquake generated the sort of media attention that might normally accompany a punishing magnitude 5 or 6 earthquake. But as with real estate sales, it’s all about location.
