How do volcanoes and earthquakes happen?
Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. First, both volcanoes and earthquakes form where one plate sinks under the other. This process, called subduction, takes place because one plate is denser than the other.
How earthquakes and volcanoes affect human life Wikipedia?
Primary effects are the direct result of an earthquake or volcanic eruption, such as buildings collapsing due to the movement of the earth or loss of life from pyroclastic flows. Examples include fires caused by the rupture of gas pipes caused by an earthquake or homelessness caused by the loss of buildings.
Why is the study of earthquakes and volcanoes important?
Scientists study earthquakes because they want to know more about their causes and predict where they are likely to happen. This information helps scientists and engineers build safer buildings – especially important buildings in an emergency, like hospitals and government buildings.
Why are volcanoes so important?
They helped cool off the earth removing heat from its interior. Volcanic emissions have produced the atmosphere and the water of the oceans. Volcanoes make islands and add to the continents. Volcanic deposits are also used as building materials.
Which is more dangerous an earthquake or volcano?
Earthquakes can cause damage by shaking, tsunami’s, and landslides. Volcanoes can cause damage by ash flows, release of gases, mudflows, lava flows, and landslides. However, earthquakes can cause disasters without the help of a volcano. Earthquakes generate seismic waves that can release great energy.
What was the longest earthquake?
Valdivia Earthquake
What’s the worst earthquake in history?
Is it safe to be outside during an earthquake?
Don’t run outside. Trying to run in an earthquake is dangerous, as the ground is moving and you can easily fall or be injured by debris or glass. Running outside is especially dangerous, as glass, bricks, or other building components may be falling.
Can earthquakes come again?
Why do tremors come again and again? In areas where there is a high risk of earthquakes, stress in the lower surfaces of the earth increases in hundreds of years. This is caused by the movement of tectonic plates, but the effect of stress is not only sudden but slowly.
