You wouldn’t detect any radiation if they detonated nukes near an underwater faultline. Water blocks radiation really well. They would notice it via seismic sensors since earthquakes look different than nukes when it comes to seismic waves.
Oh… You’d notice it pretty quick when all the radioactive remnants from the bomb are vaporized into fine dust and spread out into the ocean in a constantly spreading plume.
I bet people would notice real quick.
Edit: autocorrect had turned “vaporized” into “baptized”, that made for a real confusing sentence… 🙄

Water blocks radioactivity by becoming marginally radioactive itself. And yeah the seismic signature would be different as well.
