Question

Why are volcanoes dangerous? what are their advantage

Answer 1

Volcanoes are often covered with ash and debris. Because of this, stratovolcanoes are known for causing deadly mudslides (sometimes called lahars). These can be the result of volcanic activity, earthquakes, or even rainfall. So, even when there's no fire or ash raining from the sky, there's still an element of danger.

Volcanoes have also helped create a large portion of Earth's atmosphere, she added. Fertile soil is another advantage of volcanic activity. “In places like Japan, Indonesia, Philippines and Hawaii, volcanic material mixed in with the soil provides a lot of important nutrients,” Krippner said.
