Here’s a link to a fun essay on historical instances of interpreting earthquakes as signs of the looming end of the world: It Starts with an Earthquake
It’s a useful essay not only because it gives you some leads on possible essay topics (especially for those of you interested in historical or perhaps religious studies essays), but also because it provides a works cited list at the end, so you can mine it for more sources for your essays. If you’re interested in looking at any of those sources but are having trouble finding them, let me know.
