33. The eruption of Krakatoa in 1883 is believed to have caused a drop in global temperatures and colorful sunsets around the world.

34. The air around an erupting volcano can be filled with toxic gases, such as sulfur dioxide and carbon dioxide, which can pose a danger to human health.

35. Volcanic eruptions can trigger lahars, which are fast-moving mudflows that can destroy everything in their path.

36. Some volcanoes are located underwater, and their eruptions can create new islands or seamounts.
