Noridic Wastelands

The Noridic wastelands is a open desert filled with high radioactivity due to an incident around 2422 where a nuclear cargo vessel carrying experimental super nukes suffered an engine failure and crash in a forest region setting off a huge nuclear explosion which left a massive crater of 50 miles wide at every angle and 100 miles surrounding it in a radioactive dusty wasteland.
The Noridic wastelands is still radioactive to this day, people who are immune to radiation still live their lives normally in some town ruins.
The Noridic wastelands is around central northern Passivaria. 
The explosion from the nuclear explosion was so loud that the entire world could hear it.
People can visit these wastelands but must wear a radiation suit due to the high amounts of radiation in the zone, The area is called Noridic wastelands after the nuke experiment was developed in a secret base around the town of Noridic which got wiped out in the blast.
Travelers can sometimes find rusty old cars with skeletons around the place, but the whole place is 99% wiped out, on a rare occasion you may find buildings with some settlers inside them.
Near the center of the blast zone you may encounter puddles of radioactive goo that glows bright enough that it can be seen at night and day.
The nuclear weapon that the plane was carrying is called the Eye of Derinsaru Super Bomb
