In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. A seismograph is like a ink printer. Why do scientists study seismographs?To learn about different rock samples to determine the location of an epicenter . Answer: Triangulation requires that you determine the exact arrival time of the P and S waves produced by an earthquake for at least three different seismograph stations. Liquids dont have any shear strength and so a shear wave cannot propagate through a liquid. Seismology also can help detect nuclear explosions. Seismic phenomena are generally explained as the result of interactions and other processes at or near the edges of a few large mobile plates of lithosphere that spread apart at the ocean ridges where new surficial materials arise, slide past one another along the large strike-slip faults, and converge at the island . During an earthquake, the base moves and the mass does not.

Because of their wave movement, P waves travel through any kind of material, whether it is a solid, liquid or gas. This information helps scientists and engineers build safer buildings especially important buildings in an emergency, like hospitals and government buildings. The tip of the pen touches the drum. Several designs and variations exist, and many are easy to build with common materials. The digital recording is called a seismogram. S-waves can travel only through solids, because only solids have rigidity. Earthquake early warning systems like ShakeAlert work because an alert can be transmitted almost instantaneously, whereas the shaking waves from the earthquake travel through the shallow layers of the Earth at speeds of one to a few kilometers per second (0.5 to 3 miles per second). As a result of this, we can see that a seismograph is an equipment which are used to measure the tremors in the earth which happen in the earth, usually in the event of an earthquake to find the location of the epicenter, Therefore, the correct answer is option B, seismographs are used to measure the tremors in earth or earthquakes is there a none of the above ? Seismographs can detect quakes that are too small for humans to feel. Answer: Unlike P waves, S waves dont move straight through the Earth. S-waves dont change the volume of the material through which they propagate, they shear it. Geo.mtu.edu Seismologists study earthquakes by going out and looking at the damage caused by the earthquakes and by using seismographs. Which sources do scientists use to study the interior of Earth? If the seismographs are too far away from the event to record S-waves, several recordings of P-waves can be crunched in a computer program to give an approximate location of the source.
