Which is more dangerous 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.
How do earthquakes affect the earth?
Earthquakes often cause dramatic changes at Earth’s surface. In addition to the ground movements, other surface effects include changes in the flow of groundwater, landslides, and mudflows. Earthquakes can do significant damage to buildings, bridges, pipelines, railways, embankments, dams, and other structures.
How can we prevent earthquake damage to buildings?
To withstand collapse, buildings need to redistribute the forces that travel through them during a seismic event. Shear walls, cross braces, diaphragms, and moment-resisting frames are central to reinforcing a building. Shear walls are a useful building technology that helps to transfer earthquake forces.
How are earthquakes and volcanoes similar and different?
Earthquakes are not a geological structure like volcanoes and they do not release magma. They are violent movements of the Earth’s crust. However, unlike volcanoes, earthquakes are common to all types of plate boundary. They can take place when moving plates collide or when they become locked together.
When an earthquake strikes you should?
If you are INDOORS — STAY THERE! Get under a desk or table and hang on to it (Drop, Cover, and Hold on!) or move into a hallway or against an inside wall. STAY CLEAR of windows, fireplaces, and heavy furniture or appliances. GET OUT of the kitchen, which is a dangerous place (things can fall on you).
What are the effects of volcanoes and earthquakes?
Volcanically triggered earthquakes have the potential to cause cracks, ground deformation, and damage to manmade structures. They typically are much smaller than earthquakes caused by non-volcanic sources.
How volcanoes and earthquakes affect human life?
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.
