The Earth itself is.
Rock, soil, etc.
An earthquake's Focus is located directly under the Epicenter of an earthquake. The Epicenterof an earthquake is located on the surface of the earthquake.
No, the Haiti earthquake in 2010 was not the strongest earthquake ever recorded. The strongest earthquake ever recorded was the 1960 Valdivia earthquake in Chile, which had a magnitude of 9.5 on the Richter scale.
Earth is the medium for earthquake waves.
Rock.
A low earthquake is 1-3 magnitude, a medium earthquake is 4-6 magnitude and a high earthquake is 7+ magnitude.No. A 7.0 magnitude quake would be considered a "major" quake.Here is the scale of earthquake magnitude classes:ClassMagnitudeGreat8 or moreMajor7 - 7.9Strong6 - 6.9Moderate5 - 5.9Light4 - 4.9Minor3 -3.9

A mechanical wave is a disturbance (an oscillation) that moves through a medium. The source transfers mechanical energy into the medium itself, and the medium propagates the energy of the wave. Examples are sound and an earthquake, and a tsunami.
Since an earthquake or seismic wave is a pressure or force wave (like sound waves), it requires a material in which to propagate. So, no earthquake waves can travel through a vacuum.
No. Seismic waves travel through rock and sediment.Sea waves (tsunamis) are not generated by earthquake vibrations, but by the displacement of ocean water, which leads to the formation of waves when the crest reaches shallower water.
An increase in density of the medium generally results in an increase in the speed of an earthquake. This is because denser materials transmit seismic waves more efficiently than less dense materials, allowing the waves to travel faster through the medium.
Sound waves, they need a medium to vibrate.A2. Earthquake waves and other mechanical waves also need a medium for their transmission.Ghv. Tsunamis are a type of mechanical wave, which is the kind of wave you're looking for.
Seismic, or earthquake waves travel through the earth. They may travel through our crust, which is rocky, or through the more fluid parts, like the mantle, but the medium is the earth.
A disturbance that travels through a medium as a longitudinal wave is known as a sound wave. In a longitudinal wave, the particles of the medium oscillate parallel to the direction of wave propagation. Sound waves are an example of longitudinal waves as they require a medium, such as air or water, to travel through.
