Now here's the fun bit of information...
This is a rough outline picture of the submarine communications cables....its what allows internet and phone calls to happen.
A lot of these cables are unaffected by weather...unless its an earthquake under the ocean. Then it gets difficult. A small rockslide under the ocean and in one of the valleys that they lay these cables in...and that cable gets crushed and no more international communications. Look at that china coastline. There's just one valley under the ocean's surface that they all go through...and one day there was a rock slide that really crippled communications. Hundreds of thousands of terabytes per minute go through that trench.
Its all fun and games until the communications go silent.
