English Summary

The lesson Anak Krakatoa explains about the famous volcanic island Krakatoa in the Sunda Strait between Java and Sumatra. It begins with the definition of a volcano as a crack in the earth’s crust through which molten rock, lava, smoke, and ash erupt. Volcanoes are of three types: active, dormant, and extinct. Krakatoa is an active volcano, notorious for its violent eruption in August 1883. The eruption was so powerful that its sound was heard more than 3500 km away, dust rose 80 km high, and huge tsunamis destroyed many villages, wiping out two-thirds of the island. Later, in 1927, volcanic activity at the same spot led to the birth of a new island, named Anak Krakatoa or the “Child of Krakatoa.” The passage also explains how life gradually returned to the destroyed island through seeds, birds, and small animals. Today, Anak Krakatoa continues to erupt and grow, serving as a natural laboratory for scientists to study how ecosystems recover after disasters.

Theme / Central Idea

The lesson highlights the destructive power of volcanoes and the resilience of nature. It also shows how life finds ways to return and flourish even after massive natural disasters.

3. Question: How was Anak Krakatoa formed?

   Answer: Anak Krakatoa was formed in 1927 when volcanic material built up above the sea after Krakatoa collapsed. Lava kept flowing out, and a new mountain grew, which later became a new island.

   
   

4. Question: How did life return to Krakatoa after the eruption?

   Answer: Life returned through seeds brought by wind, sea, and birds. Small animals like ants, termites, and lizards reached the island on floating plants. Slowly, the land became rich in plants and animals again.

   
   

5. Question: Why is Anak Krakatoa important even today?

   Answer: Anak Krakatoa is important because it is still active and continues to grow. It gives scientists an opportunity to study volcanic activity and how ecosystems recover after disasters.
