What are the causes of tsunami PPT?
Tsunami is a series of wave created when water is moved very quickly. Tsunami is gravity wave system, triggered by vertical disturbances in ocean.
What are the effects of tsunami in points?
The majority of deaths associated with tsunamis are related to drownings, but traumatic injuries are also a primary concern. Injuries such as broken limbs and head injuries are caused by the physical impact of people being washed into debris such as houses, trees, and other stationary items.
What is the introduction of tsunami?
A tsunami is a series of long waves generated by a large and sudden displacement of the ocean. Large earthquakes below or near the ocean floor are the most common cause, but landslides, volcanic activity, certain types of weather, and near earth objects (e.g., asteroids, comets) can also cause a tsunami.
What is the conclusion of tsunami?
When an earthquake or a volcanic activity takes place, an outsized amount of water may get displaced. The displaced water forms waves. These waves, when approaching the shallow water within the coastal areas, become high and crash onto the shore. Tsunami causes widespread destruction of lives and property.
What is landslide PPT?
Definition A landslide, also known as a landslip, is a geological phenomenon that includes a wide range of ground movements, such as rock falls, deep failure of slopes and shallow debris flows. Landslides can occur in offshore, coastal and onshore environments.
How do you make a tsunami?
Walkthrough for tsunami in Little Alchemy
- water + water = sea.
- air + fire = energy.
- earth + energy = earthquake.
- earthquake + sea = tsunami.
How is a tsunami measured?
Tsunamis are detected and measured by coastal tide gages and by tsunami buoys in the deep ocean. The tide gages measure the tsunami wave directly. In the deep ocean, sensors on the ocean floor detect the pressure signature of tsunami waves as they pass by.
What is the prevention of tsunami?
Protect yourself from the effects of a tsunami by moving from the shore to safe, high grounds outside tsunami hazard areas. Be alert to signs of a tsunami, such as a sudden rise or draining of ocean waters. Listen to emergency information and alerts. Evacuate: DO NOT wait!
What are the types of tsunami?
Tsunamis can occur when the earthquake is shallow-seated and strong enough to displace parts of the seabed and disturb the mass of water over it. There are two types of tsunami generation: Local tsunami and Far Field or distant tsunami.
What is flood Slideshare?
Introduction Flood is overflow of excess water that submerges land and inflow of tide onto land. Most frequent and deadliest Occurs when the geomorphic equilibrium in the river system is disturbed because of- Intrinsic threshold Extrinsic threshold Introduction.
