The motion of the base with respect to the mass is commonly transformed into an electrical voltage. In seismology, Love waves (also known as Q waves (Quer: German for lateral)) are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. They travel through the Earth in curved paths, but they change direction suddenly when they pass through the boundary between substances in different states. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter.

As a transverse wave passes the ground perpendicular to the direction that the wave is propagating. 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 . Oother students did not want to socialize with them. Scientists use seismographs. It is used to detect seismic waves generated by earthquakes and nuclear explosions.

Why do scientists study seismographs Brainly? Why do scientist study seismographs Brainly? , ascular The velocity of s waves going through the asthenosphere decreases, which tells us that peridotite contains a few percent partial melt, but not enough to stop s waves. But some animals may be able to detect P-waves before the S-waves arrive. How do P waves and S waves travel through the Earth? Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. Seismographs can detect quakes that are too small for humans to feel. The electrical voltage is recorded on paper, magnetic tape, or another recording medium. The goal of a seismograph is to accurately record the motion of the ground during a quake. 1 How do scientists monitor and study earthquakes?
