Reducing the Impact of Natural Hazards

What is a volcano?

• A movement of tectonic plates causing seismic waves to be produced

• An eruption of molten rock from beneath the Earth's crust

• A huge wave of water that can wash away coastal towns

• A huge canyon deep under the ocean

What is an earthquake?

• An eruption of molten rock from beneath the Earth's crust

• A large canyon deep under the ocean

• A build up of pressure between pieces of the Earth's crust causing seismic waves.

• A large wave of water that can sweep away coastal towns

What can scientists do to reduce the impact of tsunamis?

• Use tiltmeters to monitor changes in the land

• Measure poisonous gas levels on land

• Use monitors out in the ocean to monitor wave heights and send messages to the coast

• Check lava flows

What can we do to reduce the impact of volcanoes?

• There is nothing that can be done

• Monitor gases, temperature changes and earth movements close to the volcano.

• Build earthquake proof structures

• Do drop, cover and hold on drills
