IMS Map
This is a map of all IMS monitoring stations.
Note that most markers are not accurately placed. That's deliberate. Apparently, the CTBTO doesn't want you to know the exact locations. In some cases, we've placed the marker closer. After all, if a hostile entity were out to destroy monitoring stations, how difficult would it be to find them? Plus, given the significant redundancy, how many would need to be destroyed to severely degrade the system?
The CTBTO also has a map that shows the locations of its monitoring stations and the locations of past nuclear explosions.
