(though it's pretty likely that in HPMOR-verse, all volcano eruptions, earthquakes, tsunamis, etc. are caused by Magic Gone Wrong)
I doubt it, since first off, many of them long predate humans, and second, something would have to be seriously wrong with our model of geology for plate tectonics to not sometimes result in volcanoes or earthquakes.
Sheerly for the sake of playing devil's advocate (do we have an alternate term here?):
The "fact" that volcanoes and earthquakes occur because of magic doesn't mean that our model is wrong. The tension that is building up for these natural disasters would still be there--the magic would just trigger it earlier that it would have otherwise.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 95. The previous thread has passed 300 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24.
