The seismometers are instruments that measure volcanic eruptions and seismic waves on the planet. It is formed by a fixed pendulum with a needle. The needle writes in a paper roll the movements of the earth. Depending on waves size, we can see the strength and duration of the earthquake. This measurement tool is used by geologists.
