1815 Apr 10, A third of the 13,000 foot Mount Tambora on Sumbawa Island, Indonesia, was blasted into the air. Some 50,000 islanders were killed and the whole planet was shrouded in a debris of sulfuric droplets. In 2006 scientist reported finding traces of Tambora society. Tsunamis and starvation that followed killed an estimated 60-120 thousand people.
As you can see, there were wars world wide as well as some natural catastrophes and those people probably thought they were close to seeing Jesus too.
