How do volcanoes affect the land and people around it?

Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields. Lava can kill plants and animals too.

What is the impact of volcano on property?

Eruptions can produce such features as floods, pyroclastic flows, and mudflows that can cause major loss of life and property burying towns and villages within minutes (Figure 1). Eruptions can rapidly change productive landscapes to virtual deserts.

How do volcanoes destroy land?

The flowing lava burns, melts, and destroys everything it touches including farms, houses, and roads. A volcanic eruption forever changes the landscape. Though volcanoes destroy, they also create mountains, islands, and, eventually, incredibly fertile land.

How does a volcanic eruption change the shape of the land?

Volcanoes occur when cracks in the Earth’s surface allow hot molten rock to rise up from below the crust. A volcanic eruption can change the shape of a mountain by blowing parts of it away, but volcanic eruptions can also build up the land around a volcano when lava flows out and hardens on the surface.

Which type of volcano is most common?

Cinder cone volcanoes

What is the three major types of volcano?

What happens if Yellowstone volcano explodes?

If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. In fact, it’s even possible that Yellowstone might never have an eruption that large again.
