Java and sumatra on world map9/10/2023 ![]() ![]() After the eruption of Krakatoa, the ash traveled high into the atmosphere and circled the earth. The volcanoes in this region have a history of exploding violently with lots of ash. While there is a small portion of the original island, a new volcano called Anak Krakatoa has been slowly growing since 1959. ![]() A new volcano is forming where the island of Krakatoa once stood. Java and Sumatra grow a lot of coffee in the nutrient rich volcanic soils. The islands in this region are mostly the tops of large underwater volcanoes that have slowly grown out of the ocean over time. The deepest part of the Java Trench is 7,450 m (24,442 ft). A trench is actually the deepest part of an ocean even though it is relatively close to the coastline. The Java Trench is a deep underwater valley running long the coast of Java and Sumatra in Indonesia. It was the third largest ever in recorded history and resulted in over a quarter of a million deaths as a result of earthquake and tsunamis. In 2004, a magnitude 9.1 earthquake occurred in the Java Trench. The explosion is considered to be the loudest sound ever heard in modern The sound of the eruption was heard across the ocean 4,800 km (3,000 miles) away. The volcano almost completely destroyed itself and caused 40 m (130 ft) tsunamis that traveled across the ocean leveling villages. When the dust settled the island was completely gone. In 1883, the island of Krakatoa started belching out gas, ash and steam and eventually erupted violently on August 26. The geologic activity around the Java Trench has resulted in some significant (infamous) events throughout history. There are at least 76 volcanoes but it is also known for powerful earthquakes and tsunamis. Indonesia is home to more volcanoes than any other country in the world. ![]()
