Most surface waves are caused by the action of 'earthquakes' or 'winds'?
Surface waves are primarily caused by earthquakes rather than winds. Earthquakes generate seismic waves that propagate along Earth's surface, leading to ground shaking. Winds, on the other hand, primarily generate ocean surface waves rather than seismic surface waves.
What is a seismic crew?
Seismic crews create hundreds of small earthquakes using explosives and other energy sources. These vibrations are precisely measured by specialized equipment to compile a three-dimensional map of the sub-surface rock formations and petroleum reservoirs.
What type of wave can be generated by underwater earthquakes?
Underwater earthquakes can generate seismic waves, including primary (P) waves, secondary (S) waves, and surface waves. These waves can travel through the Earth and water, causing tsunamis on the ocean's surface.
What are the principles of seismic stratigraphy?
Seismic stratigraphy is a geologic approach to the interpretation of seismic data, allowing their application based on physical stratigraphy. Primary seismic reflections parallel the surface and nonconforming surface of the strata.
What is the point on earths surface where the seismic activity is strongest in an earthquake?
The vibrations of a earthquake are strongest where the falt line is.

What material was used to power the seismic equipment left on the lunar surface by Apollo missions?
Plutonium-238 was used as the power source for the seismic equipment left on the lunar surface by the Apollo missions. This radioactive isotope provided a long-lasting and reliable source of energy for the instruments to continue collecting data on moonquakes and the lunar interior.
Which seismic wave causes damage to da surface?
The surface wave.
The point where rocks break and release energy in the form of seismic waves?
The point where rocks break and release energy in the form of seismic waves is known as the focus or hypocenter of an earthquake. This is typically located beneath the Earth's surface along a fault line where the stress within the rocks exceeds their strength, causing them to fracture and generate seismic waves.
What do seismic waves consist of?
Surface Waves
What type of wave can be generated by underwater earthquakes?
Underwater earthquakes can generate seismic waves, including primary (P) waves, secondary (S) waves, and surface waves. These waves can travel through the Earth and water, causing tsunamis on the ocean's surface.
Which type of seismic wave travels on top of Earths surface?
A Surface Wave.
Do seismic waves travel along earths surface?
Yes, Surface waves, a type of seismic wave, travels along the surface, or appears to, as it loses energy exponentially as it goes away from the surface.
Are surface waves the fastest seismic waves?
No, they are in fact the slowest! The fastest seismic waves are P-waves.
Which type of a wave is a surface wave?
a seismic wave
Are surface waves the first to arrive at the seismic facility?
No
