Any hydrologists/geologists out there that can ease our minds about the Disney parks and resorts? Crazy stuff!
I'm a geologist.
No easing your mind, they happen, little to no warning, they can be big or small(ish).
On the brighter side Disney probably doesn't want them as much as you do so they could have programs in place, such as looking for active signs of subsidence, they probably would notice unusual cracking in the structure in the utiladors below the park because of weakened substrate. Or they maybe be actively monitoring the ground in key places.
Keep in mind though sinkholes taking lives are rare, the media plays this up because they suck as actual journalists. Think of how many stories you have read/heard about and place that in context of a country of 300 million people. Could you one day be swallowed by a sinkhole, it's possible however very unlikely. Its like could I have abs like Hugh Jackman (hold on let me check). Nope, could I? Possible, but since I don't plan on doing another sit up as long as I live, very unlikely.
The best protection I can advise is for everyone in your party to pick a partner, keep 25 feet apart and tether yourselves together with rope.
Hope this helps. I'll let you know if the ab thing ever happens.
