Etymology:
The word "seismogram" derives from two Greek words:
Meaning:
A seismogram is a graphic record of the vibrations produced by an earthquake or other seismic event. It is a plot of the ground motion (amplitude) over time.
Origin:
The first seismograms were produced in 1880 by the Italian seismologist Luigi Palmieri. He used a device called a seismometrograph, which consisted of a pendulum attached to a recording drum. As the ground shook during an earthquake, the pendulum would swing, causing the drum to rotate and mark a line on a piece of paper.
Modern seismograms are usually recorded using digital seismometers, which convert the ground motion into an electrical signal that is then amplified and processed by a computer. Seismograms can be used to determine the location, magnitude, and other characteristics of an earthquake.
