You can't "detect" an EMP until after it hits, as it moves at the speed of light. Also, even if the pulse is weak enough to not have much of an effect, you can't warn anyone else without using a quantum entanglement-based communication device (such as my quantum telegraph, US patent pending), as that is the only currently known method of faster-than-light communication, and even if you had THAT, light travels fast enough to circle the globe in 1/7 of a second.
