Three earthquakes were reported near the Phoenix area on Sunday night.

The first occurred at approximately 9 p.m. and registered as a 3.2, according to the U.S. Geological Survey.

A magnitude 4.1 earthquake was recorded by the U.S. Geological Survey at around 11:30 p.m., followed by a 4.0 earthquake about 20 minutes later.

All three earthquakes were centered about 7 miles north of Black Canyon City.

There are no reports of any damage or injuries.

The earthquakes were felt by people in Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, Apache Junction, San Tan Valley and other Valley cities. They were also felt by people in cities and towns north of the Valley, as well as New Mexico and Nevada.

Many people are wondering if there will be any aftershocks on Monday, but Zachary Reeves with the U.S. Geological Survey said if there are, they may be too small to be felt.

“Typically, aftershocks can occur for weeks or even months for very big earthquakes, but usually the biggest aftershock is about a magnitude smaller so even if there are aftershocks that we detect, they might not be felt in this area,” Reeves said.

Our TV assignment desk was flooded with emails from viewers who felt the quake and aftershocks.

“My dog was hysterical,” Maureen Spencer said. “My friend at the ranch, north of Carefree Highway, said her entire house was shaking.”

Jody Kasun likened the sound of the quake to a bomb going off.

“I have felt earthquakes before and have never heard any sound like that,” Kasun said.

Charlotte Treuil described the commotion at her apartment north of Jomax Road.

“Chair began shaking several inches, glass doors creaking and popping. Cat running from room to room. Building swayed,” she wrote.

Another resident, Veida Bull, lives in Black Canyon City.

“We had a second earthquake that was stronger than the first shook the house, very scary,” she wrote.

It was a frightening experience for many people and the timing around Halloween weekend couldn’t have been worse.

“I had just watched the Exorcist on Friday so when my bed shook I almost had a heart attack,” resident Charissa Wick reported.

A professor geology at Arizona State University said earthquakes in Arizona are not unexpected.

“It’s a little bit unusual for Arizona but we’ve seen these kinds of events before,” Ramon Arrowsmith said.

On May 5, 2015, a small earthquake just north of Sedona rattled parts of Yavapai and Coconino counties. The United States Geological Survey reported the 3.2-magnitude earthquake just after 2 a.m. about 5.6 miles north of Sedona.

Arrowsmith said it’s unlikely we’ll get any aftershocks more powerful than the ones that have already occurred.

“So we might expect going forward over the next 24 hours a few aftershocks, some smaller events in the same area.”

The largest earthquake in Arizona history was a magnitude 5.6 on July 21, 1959., according to the USGS.
