NEW ZEALAND VOLCANO - SOUND

The video discusses the volcanic activity in the North Island of New Zealand, focusing on Nauruhoe, which is expanding and forming a new cone. It highlights the thermal extremes present and describes nearby Mount Ruapehu, which last erupted in 1945, and White Island, where a tragic eruption occurred. The importance of constant monitoring by volcanologists is emphasized to understand and predict volcanic behavior.

What is the main reason for Nauruhoe's increasing size?

• Erosion of surrounding land

• Formation of a new cone in the crater

• Human construction activities

• Melting of snow on its slopes

What natural phenomenon is described as nature's safety valve in the context of Nauruhoe?

• Earthquakes

• Subterranean fires belting steam and smoke

• Heavy rainfall

• Landslides

When did Mount Ruapehu last erupt?

• 1985

• 1925

• 1945

• 1965

What tragic event occurred on White Island?

• A massive earthquake destroyed the island

• A tsunami swept away the coastal areas

• A volcanic eruption claimed the lives of 15 workmen

• A forest fire engulfed the island

Why do volcanologists keep a constant watch on volcanic activity?

• To monitor the erratic pulse of Mother Nature

• To measure air pollution levels

• To predict weather changes

• To study wildlife patterns
