What is seismogram in earthquake?
Table of Contents
A seismogram is the recording of the ground shaking at the specific location of the instrument. On a seismogram, the HORIZONTAL axis = time (measured in seconds) and the VERTICAL axis= ground displacement (usually measured in millimeters).
What do you mean by Sesmograph?
noun. an instrument that registers and records the features of earthquakes.
What is seismograph explain with example?
The definition of a seismograph is a measuring instrument for earthquakes that tracks duration and magnitude. A device used to measure the duration and magnitude of a San Francisco earthquake is an example of a seismograph. noun. 2.
What is seismograph one word answer?
A seismograph is an instrument scientists use to measure the strength of an earthquake. Geologists or geophysicists who study earthquakes are called seismologists, and the tool that helps them study the shaking of the ground is called a seismograph or seismometer.
What is seismogram used for?
Seismograms are used to determine the location and magnitude of earthquakes. An earthquake’s magnitude may be considered to vary as a function of the amount of energy released at the rupture point.
What is the importance of a seismogram?
A modern seismograph can help scientists detect earthquakes and measure several aspects of the event: The time at which the earthquake occurred. The epicenter, which is the location on the surface of the earth below which the earthquake occurred..
What is a seismograph kid definition?
Kids Definition of seismograph : a device that measures and records vibrations of the earth.
Which is measured by seismograph?
A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves.
What is the kid definition of seismograph?
A seismometer or seismograph is an instrument that measures motions of the ground, including those generated by earthquakes, nuclear explosions and other sources. Records of seismic waves called seismograms allow us to map the interior of the Earth, and to find and measure the size of those different sources.

How does a seismogram Show earthquake waves?
A seismogram shows earthquake waves by the lines on the paper. The bigger the line, the larger the earthquake and the smaller the line, the smaller the earthquake.

How is earthquake measured using sesimograph?
Earthquakes are usually measured using seismographs and accelerometers. A seismograph works by using a suspended needle attached to a large mass that ‘draws’ on a piece of paper. When the ground moves, along with the paper, the suspended needle do…
