Anak Krakatau is a volcanic island located in the Sunda Strait between Java and Sumatra in Indonesia. It emerged in 1927 from the caldera of the infamous Krakatoa volcano, which erupted catastrophically in 1883. The name "Anak Krakatau" means "Child of Krakatoa," reflecting its origin. The island is known for its frequent volcanic activity, including eruptions and ash emissions. The island is part of the Krakatoa archipelago and is monitored closely by scientists due to its potential impact on surrounding areas. Anak Krakatau plays a significant role in the study of volcanic activity and the geological processes that shape our planet. Its eruptions can affect air travel and local ecosystems, making it an important site for research and observation.
