What type of volcanoes are in Indonesia?
Most volcanoes in Indonesia consist of stratovolcanoes, but this does not mean that the resulting eruptions are always explosive and they have a long period.
What is fragmented lava called?
Felsic lava Felsic or silicic lavas have a silica content greater than 63%. They include rhyolite and dacite lavas. The lavas typically fragment as they extrude, producing block lava flows. These often contain obsidian. Felsic magmas can erupt at temperatures as low as 800 °C (1,470 °F).
What are the 3 different states a volcano can be in?
What are the different stages of volcanoes? Scientists have categorized volcanoes into three main categories: active, dormant, and extinct. An active volcano is one which has recently erupted and there is a possibility that it may erupt soon.
What is the general name for fragmented ejecta from a volcano?
pyroclastic fragments
Pyroclastic flows have their origin in explosive volcanic eruptions, when a violent expansion of gas shreds escaping magma into small particles, creating what are known as pyroclastic fragments.
What is the largest volcano in Indonesia?

What happens if you touch lava?
Lava won’t kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn’t get out, you wouldn’t die. With prolonged contact, the amount of lava “coverage” and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!

When did the Krakatau volcano in Indonesia erupt?
Krakatau erupted violently in 1883, destroying two-thirds of the island and leaving a large caldera under the sea. This cataclysmic explosion was heard as far away as the island of Rodrigues near Mauritius (approx. 4,800 kilometres (3,000 mi) away).
