" A deadly earthquake in Mexico led to the discovery of an ancient Aztec temple "

In the wake of the devastating quake of September 2017, archaeologists used radar to scan the 13th-century Teopanzolco pyramid south of Mexico City, dedicated to the Aztec rain god Tláloc, for potential damage. Instead, they found traces of an even older temple inside, thought to date back to 1150 A.D. Later in the year, another team of researchers confirmed the existence of a hidden tunnel underneath the Pyramid of the Moon in the ancient city of Teotihuacán, which they think its builders might have intended as a symbolic passage to the underworld.
