What type of lava came out of Krakatoa?
Mount Krakatoa’s lava was known to be made of dacite or rhyolite. This explains the magnitude of its eruption. Generally speaking, volcanic eruptions are more explosive if their lava is composed of dacite or rhyolite. They are cooler and stickier than basalt, allowing them to accumulate pressure before being set free.
How did Anak Krakatoa form?
On December 29, 1927, Anak Krakatoa emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa. Due to its young age, the island is one of several in the area which are of considerable interest to volcanologists, and the subject of extensive study.
Where does lava come from and why do volcanoes erupt?
The magma (molten rock) which is erupted from a volcano comes from deep inside the earth — usually from about 150 kilometers deep. The pressure there is enormous. The pressure forces the magma to rise through the crust of solid rocks, creating a volcanic eruption.
Do we have volcano in India?

Where is the Krakatoa volcano?
Krakatoa Island (Krakatau in Indonesian) is a part of Indonesia and lies close to the Java Sea. It is located in between the Islands of Java and Sumatra. Before the eruption, the volcano stood 790 m above sea level. From 1927 till today, in its place now lies the Child of Krakatoa Island as a new volcano has emerged since the eruption of 1883.
What happened in the 1883 Krakatoa eruption?
In August 1883, the eruption of the main island of Krakatoa (or Krakatau) killed more than 36,000 people, making it one of the most devastating volcanic eruptions in human history. Where Is Krakatoa? The volcanic island known as Krakatoa is located in the Sunda Strait, between the islands of Java and Sumatra.
How many people died in the Krakatoa volcano eruption?
At least 36,417 people died, and many more thousands were injured, mostly from the tsunamis that followed the explosion. The eruption destroyed two-thirds of the island of Krakatoa. Eruptions in the area since 1927 have built a new island at the same location, named Anak Krakatau (which is Indonesian for “Child of Krakatoa”).
What is the origin of the Indonesian name Krakatau?
The origin of the Indonesian name Krakatau is uncertain. The Smithsonian Institution’s Global Volcanism Program cites the Indonesian name, Krakatau, as the correct name, but says that Krakatoa is often employed.
