The immediate surroundings of an active volcano probably aren't the greatest place to build your home. That didn't stop the locals of Karo, Indonesia building around Mount Sinaburg, although they quickly learned the error of their ways.
When the volcano erupted in 2010, the residents fled in terror. Some of them came back afterward, but a second eruption in 2015 proved to be the final straw. All these homes (and the ornate church) are now empty, and ever shall be.
