The motion of the base with respect to the mass is commonly transformed into an electrical voltage. 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. The pen also starts vibrating and paper starts moving under the pen recording the movement of the pen. There are two ways in which scientists quantify the size of earthquakes: magnitude and intensity. Students also viewed.

These measurements allow scientists to estimate the distance, direction, magnitude, and the type of earthquake that just occurred. Using digital stations instead of analog stations provides several important benefits: The high and low gain sensors provide data on scale for both small and large earthquakes. Because the earths mantle becomes more rigid as its depth below the asthenosphere increases, S-waves travel faster as they go deeper in the mantle. The magnitude does not depend on where the measurement is made. People who study seismology examine earthquakes and how waves of energy move through the Earth's layers.. D. to observe temperature changes on Earth's surface. 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 . sudden movement along faults within the Earth Scientists currently monitor underground movements, such as earthquakes and nuclear tests, using seismometers instruments that measure the motion of those events at the Earths surface.
