Indonesia tsunami caused by volcano eruption

The video discusses the formation of stratovolcanoes through layers of lava and ash, focusing on the Strombolian eruption type characterized by gas slugs. It highlights the changes in a specific volcano's structure, analyzed through radar satellite images, showing a significant reduction in height due to steady eruptions. The video also covers the impact of these eruptions, leading to material loss and structural changes.

What is a key characteristic of stratovolcanoes?

• They are found only in Indonesia.

• They are formed by a single eruption.

• They consist of layers of lava and ash.

• They are the tallest type of volcano.

• Around 1828

• Around 2028

• Around 1728

• Around 1928

What causes the magma to be thrown into the air during Strombolian eruptions?

• Lava cooling

• Earthquakes

• Gas slugs bursting

• Wind pressure

Which satellite is NOT mentioned as being used to analyze the volcano?

• European Union Sentinel

• Japan's Space Agency

• German Terra SARX

• NASA's Hubble

What was the original height of the volcano before the steady eruptions?

• 210 meters

• 110 meters

• 340 meters
