a half-century of our most earth- rattling mining and nuclear tests
The Earth is covered in a network of seismic sensor to measure shakes and quakes. Sometimes, we humans are the cause. Here are those times…
Ok, blast off!
Blast Map
a half-century of our most earth-rattling mining and nuclear tests
These points represent really big blasts over the past half century. As global networks of seismic activity detectors came online (lots and lots of them), they also, not necessarily accidentally, picked up earth shaking explosions as well. The incidents you see here were deemed to be either quarry blasting or nuclear testing. Read all about it at the Advanced National Seismic System’s website.
