For Internet, the maximum run for cat 6 cable is 100m. For anything even approaching that, I would run fiber instead. But for my installation I used one of these:
Ideally, you would use two for a point to point link, but I set mine up to connect to the house wifi.
There is an online tool to convert the data to sound - here is an example of a local earthquake:

As for Oregon geology … an interesting topic. The most “frightening” part is going back to the time when the descending Pacific plate melted and began to “swirl” back upwards where it hit the US plate and continued back out towards the Pacific … forming a counter-clockwise swirl. This dragged a portion of the plate out towards the Pacific, forming a several hundred mile long crack in Easter Oregon, through which lava poured, forming a lava field covering ~80,000 square miles and several miles deep.
That’s a bit simplified 
but you get the idea. And, of course, nothing to stop it happening again tomorrow.
