It amazes me that these events seem "frequent" when you look at them overall, but then extremely rare when you realise how far apart some of them are (millions and millions of years). It really makes you realise just how small a window of time human existence has been given. We may see one or two major geological events in all of human histroy if we're lucky (or unlucky, depending on what they are!).

Not wishing to be a smart-arse, but I can't think of any major geological event that we would consider ourselves lucky to observe.

I bet many geologists would consider themselves lucky to observe some major geological events. Just as long as it's safe enough for their person.

Fair enough. Maybe it depends on the definition of "major"

> Most important for present-day inhabitants of the area, the impact disrupted aquifers. The present freshwater aquifers lie above a deep salty brine, remnants of 100–145 million year old Early Cretaceous North Atlantic seawater, making the entire lower Chesapeake Bay area susceptible to groundwater contamination.

Amazing. And a bit unsettling.

The problem with the really big geological events is that they have no safe observation distance anywhere on Earth.

I mean, I'd love to see a 3 mile asteroid strike the Earth, just for the sake of observing so many cascading disaster effects...... so long as I could do it from space, while viewing an alternate version of the Earth, in which I don't have to live afterwards.
