what island in Mexico is called the silent zone? What it is taking place in that area for that to happen?

Answer 1

It is not an island Tuty, it is a patch of desert where radio transmissions do not exit or enter. My little brother worked there one year for the Mexican telephone company. They had to put the antennas and repeaters along the mountain ranges that border this (something like 2,000 sq. mi.) Zone of Silence.

He tells me that he witnessed strange, unidentified nocturnal lights almost every night. The wildlife and plant life there was also strange. Jackrabbits, coyotes and snakes that were somehow... different. He also tells me that occasionally he would come across inhabitants there that spoke no dialect that he could understand. We are, of course, fluent in Spanish and recognize Nahuatl, but he tells me this language those inhabitants spoke was completely unrecognizable.
