When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, o

Answer 1

you have the primary wave (P-wave) which is more or less the antagonizer to the Secondary wave (S-wave) and when reading a seismograph, you would start with how long it lasted by measuring the p-s interval which is when you start where the p-wave starts to the begining where the s-wave begines.

you would measure the amplitude by the height of the initial big (squiggle) on the s-wave.
it sounds complicated because there are other measurments to compare to get the magnetude of the earthquake (richter scale)

Answer 2

P is a compressive wave, like a sound wave. S is a transverse or shear wave, like a light wave. [See source for an animation.]

When an earthquake happens, both P and S waves are generally initiated. Some materials transmit S waves and some do not. Fluids or loosely packed soil do not transmit S waves, for example. (The exception is on the surface of a fluid were one can see ripples/waves formed.)

The Earth's molten core, for example, does not transmit S waves, but it will transmit P waves. S waves actually reflect off the core. The lack of S waves in a seismograph is a major indication that the causing earthquake was on the other side of the Earth from where the seismograph was located.

When S waves hit the surface, they are called L (for long) waves and these are the waves that cause the most damage in general. [See source.]

Artifacts, like bridges and buildings, respond to P and S waves differently depending on their design, materials, and locations. For example, very tall buildings can be violently whipped about by S waves and eventually brought down, whereas the P waves will simply jolt the buidlings upward, shaking things up inside, but not bringing them down (unless the earthquake is very very strong).

S or L waves can also turn landfill to the consistency of pudding, an effect called liquifaction. As you can imagine, a building sitting on pudding does not stand up very well.

Answer 3

P (Primary) Waves and S (Secondary) Waves.

Answer 4

I think he liked girls with attitude. Because apparently Debbie Rowe what we've seen of her she's kind of a hag, and Lisa Marie seemed to have this eff off look to her all the time, and even though he wasn't "with" tatiana, she seemed a little off. And not all his women were tall, Lisa Marie is fairly short [5'2]. I think he just loves all women??

Answer 5

Try these sites. I think there is a seismic wave also.

Answer 6

Yes, you are correct !
