Explanation:
In may 2017 another nearby tunnel of waste partially caved,in sending the Hanford site into emergency lockdown.The partial collapse of tunnel 1 led to the federal investigation and decision to seal up both tunnels with grout.
It was located near the present day city of Mexico City. It formed a confederacy with Texcoco and Tlacopán and was the Aztec capital by the late 15th century. Originally located on two small islands in Lake Texcoco, it gradually spread through the construction of artificial islands to cover more than 5 square miles. Hope this helped :))
