National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @babaktafreshi A close-up view of the constantly erupting Pacaya, the most active of 37 live volcanoes in Guatemala. Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, which is why communities tend to live close to these extremely dangerous mountains. This has allowed civilizations to flourish in human history, but it has also caused some of them to disappear.
