WebAnswer (1 of 4): P waves are compression waves along the axis of source vibration. S waves are shear waves perpendicular to axis of compression. Best way to test the difference … WebSeismic waves are caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake. Volcanic eruptions, explosions, landslides, avalanches, and even rushing rivers can also cause seismic waves. Seismic waves travel through and around the Earth and can be recorded with seismometers.

WebThe P-wave is always positive in lead II during sinus rhythm. The P-wave is virtually always positive in leads aVL, aVF, –aVR, I, V4, V5 and V6. It is negative in lead aVR. The P-wave is frequently biphasic in V1 (occasionally in V2). The negative deflection is normally <1 mm. P-wave duration should be ≤0,12 seconds. WebBody waves are composed of two principal types; the P (primary) wave, comparable to sound waves, which compresses and dilates the rock as it travels forward through the Earth; and the S (secondary) wave, which shakes the rock sideways as it advances at barely more than half the P-wave speed.

So, along Earth’s surface they move at speeds of between 3 and 4.8 kilometers per second (1.9 and 3 miles per second). As an S wave passes through a material, the site of its passing moves from side to side or up and down (as compared to the direction the wave is traveling).

WebS-waves cannot travel through air or water but are more destructive than P-waves because of their larger amplitudes Surface waves Surface waves are similar in nature to water waves and travel just under the Earth’s surface. … WebThe speed at which seismic waves travel depends on the properties of the material that they are passing through. For example, the denser a material is, the faster a seismic wave …
