Admin What waves cause the ground to move up and down?
Rayleigh waves, also called ground roll, travel like ocean waves over the surface of the Earth, moving the ground surface up and down. They cause most of the shaking at the ground surface during an earthquake. Love waves are fast and move the ground from side to side.
What seismic waves move the earth’s surface up and down?
Two examples of surface waves are Rayleigh waves and Love waves. Explain to your students that Rayleigh waves cause the ground to ripple up and down (like water waves in the ocean before they break at the surf line) whereas the Love waves cause the ground to ripple back and forth (like the movement of a snake). 8.
What type of wave as it rolls moves the ground up and down and forward to backward in the direction that the wave is moving?
Rayleigh Waves Because it rolls, it moves the ground up and down, and forward and backward in the direction that the wave is moving. Most of the shaking felt from an earthquake is due to the Rayleigh wave, which can be much larger than the other waves.
What surface wave travels fastest and moves the ground side to side?
P-waves
They travel through the interior and near the surface of the Earth. P-waves, or primary waves, are the fastest moving type of wave and the first detected by seismographs. They are also called compressional or longitudinal waves, and push and pull the ground in the direction the wave is traveling.
How do surface waves move?
In a surface wave, particles of the medium move up and down as well as back and forth in an overall circular motion. The particles don’t actually move closer to shore as the waves pass through. In shallow water close to shore, waves start to drag on the bottom of the water.
