I was reminiscing about my childhood, and one memory was that of my father calling relative in Europe. Back in the day, this would take some hours for an operator here to connect via an operator over there; I understand that comms happened via large cables on the ocean floor. Three questions came to mind:
1) Do these cables still exist? If so,
2) are they still connected in any way to comms/power networks? And if so,
3) in the event of an EMP on one side of the world, could a pulse travel between continents via such cables, thus screwing with both power grids?
Not the biggest concern for the future by any means, but an interesting hypothetical nonetheless.

1) Yes. Our ISP had a major outage last year because of a fault in the undersea cable between Perth and Singapore

So - in theory at least - a pulse could travel in this way. Cheers for that.

The Philippines relies heavily on cables under the ocean.

The cables would be at least updated to fibre optic cables rather then the old copper cables I would imagine

Even if they were, I'd imagine there's some sort of metal/wire strengthening layer within the outer insulation. I am guessing, mind you...
