When I was in college, my geology professor told us about Lake Nyos, which had formed in a volcano crater in Cameroon, West Africa. The volcano continually released carbon dioxide into the water, and in 1986 the lake flipped over. The CO2 came to the surface, rushed down into the valley, and suffocated 1700 people.

Neat project alert:

Q7A (One question, seven answers) is a brand new site. Each week there’s a new question this week, it’s “What are you wearing?” and readers get a chance to answer via email. Seven of the best answers appear the following week. Similar to what Sippey.com used to do with his occasional random question, but more structured. The site is just getting started, so send some answers in to help out, or check back in a few weeks to see what’s up.
