Last Sunday, Central Arizona was shaken by a series of earthquakes, with the tremors spread across 160 miles.
Three earthquakes occurred near Black Canyon City, Arizona, according to reports from CNN.
The first quake hit with a magnitude of 3.2 around 9 p.m. local time, followed by a second quake of 4.1 magnitude two hours later. The trembling ended with a third quake of magnitude 4.0 twenty minutes later.
The quakes ranged 3 miles in depth, according to U.S. Geological Survey.
Residents of Phoenix, who were 45 miles away from Black Canyon City also felt the tremors, and other locations include Peoria, Cave Creek, Glendale and Scottsdale.
Several residents spoke out after the quake stating about their worries.
Councilwoman Lauren Kuby of Tempe City told that she had felt a rumble, and a slight movement followed by a thud, and she thought that her dog was falling.
Although earthquakes are relatively rare in Arizona, yet they have occurred. The last notable quake of the area was one of 4.7 magnitude, which hit the Sedona area of North Central Arizona in 2014, according to Latinos Post.
Another notable occurrence was in 2009 in Baja California, which ranged in magnitude from 5.0 to 6.9, and were felt as far as north of Phoenix.
Zachary Reeves of the USG Survey in Golden, Colorado commented on the quakes by saying that they were uncommon, but not powerful enough. However, they were unusual because of the fact that the smaller quake came first.
However, no immediate injuries were reported in the quake.
