Which type of surface wave causes the most surface destruction?
Rayleigh waves
There are two types of surface waves: Love and Rayleigh waves. Love waves move back and forth horizontally. Rayleigh waves cause both vertical and horizontal ground motion. These can be the most destructive waves as they roll along lifting and dropping the ground as they pass.
What is the strongest surface point of an earthquake?
The location inside the Earth where an earthquake begins is called the focus (or hypocenter) of the earthquake. The point at the Earth’s surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake.
Which waves are most destructive?
Of the two types of surface waves, the L-waves are the most destructive.
Where will most of the surface destructions take place?
The focuses of most earthquakes are concentrated in the crust and upper mantle. The depth to the center of the Earth’s core is about 6,370 kilometers (3,960 miles), so event the deepest earthquakes originate in relatively shallow parts of the Earth’s interior.
Why surface wave is the most destructive?
Surface waves are slower than body waves. It is the surface waves which cause most property damage because surface waves produce more ground movement and travel more slowly, so they take longer to pass.
What is earthquake Class 5?
Answer: A sudden movement of a part of the Earth’s surface is called earthquake. They are caused by severe shock waves that travel through the solid rocks from the Earth’s crust to the surface.
What are the 5 earthquake hazards?
Earthquake Hazards
- Ground Shaking. If an earthquake generates a large enough shaking intensity, structures like buildings, bridges and dams can be severley damaged, and cliffs and sloping ground destabilised.
- Tsunami.
- Landslides and Rockfalls.
- Subsidence and Lateral Spreading.
- Liquefaction.
Which class of earthquake are most destructive?
5. Which class of earthquakes are most destructive? Explanation: Earthquakes of class A are highly destructive whereas those of class E are not of any significance in relation to engineering structures.
What cause more damage Love or Rayleigh waves?
Love waves cause more damage than Rayleigh waves, but both are highly destructive because they occur near the surface of the Earth.
