Krakatoa is a big mountain in Indonesia that was really angry and exploded a long time ago in the year 1883. It was so loud that people many miles away heard it and that was just the beginning. The explosion was really powerful that it sent a lot of hot rock, ash, and gas shooting up in the sky.
The explosion made the mountain explode into small pieces, and it created a really big hole in the ground where it used to be. The explosion was so massive that it made the sea water move, and big waves called tsunamis were made. People living in towns near the volcano were scared and had to leave their homes because of the hot rocks and ash that were falling down on them.
The eruption of Krakatoa was one of the biggest and most dangerous in history. The explosion was heard over 3,000 miles away, and it killed more than 36,000 people. It affected the weather globally and made it colder by blocking the sunlight with all of the ash that was in the air.
Even though it was really scary, we can now study the eruption of Krakatoa to understand more about volcanoes and how they can impact our planet.
