A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground ...
As nouns the difference between seismograph and seismometer is that seismograph is an instrument that automatically detects and records the intensity, direction and duration of earthquakes and similar events while seismometer is (geology) a device used by seismologists to detect and measure seismic waves and therefore locate earthquakes etc; a seismograph.
A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions, and explosions. Seismometers are usually combined with a timing device and a recording device to form a seismograph. The output of such a device—formerly recorded on paper (see picture) or film, now recorded and processed digitally—is a seismogram.
A seismometer (the term seismograph may be used to describe a seismometer combined with an instrument for recording and displaying the amplitude and frequency of the seismic waves that the ...
Seismograph, instrument that makes a record of seismic waves caused by an earthquake, explosion, or other Earth-shaking phenomenon.Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical changes, which are processed and recorded by the instruments’ analog or digital circuits. The terms seismograph and seismometer are often used interchangeably ...
Seismograph (Seismometer) What is a seismograph. A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive ...
seismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.
A seismometer is the internal part of the seismograph , which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a...
QM-4.5LV Seismometer for School, Office & Home. The Infiltec QM-4.5LV compact seismograph is designed for school, office and home use to detect earthquakes worldwide.
These seismogram displays depict ground motion recorded by seismograph stations in real-time, updated every few minutes. Each plot represents 24 hours of data from one station.
