Zechariah prophesies an earthquake which is equal in severity to one that occurred in the time of Uzziah, King of Judah. The historical earthquake that this refers to was prophesied by Amos.
Popular science (SciPop) wants you to believe in an extraterrestrial impact when a meteor hit the Earth. Amos saw it coming. Uzziah tried to stop it. Isaiah began his prophetic ministry standing in its smoking ruins.
