What is the use 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 seismographic network.

What is a seismograph diagram?

An instrument used for recording the vibrations caused by earthquakes is known as seismograph or seismometer. The vibrations are recorded on a strip of paper and the diagram produced is known as a seismogram.

What is your 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.

What is a seismograph 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.

What is seismograph and seismogram?

The terms seismograph and seismometer are often used interchangeably; however, whereas both devices may detect and measure seismic waves, only a seismograph possesses the capacity to record the phenomena. A record produced by a seismograph on a display screen or paper printout is called a seismogram.

What are the three seismographs?

Modern seismometers include three (3) elements to determine the simultaneous movement in three (3) directions: up-down, north-south, and east-west. Each direction of movement gives information about the earthquake.

What is seismograph class8?

An instrument is used to detect and record earthquakes is called a seismograph. It consists of a metal rod attached to a fixed base. During an earthquake, the base moves, but the rod does not move.

How do you read seismograph data?

The seismogram is “read” like a book, from left to right and top to bottom (this is the direction that time increases). As with a book, the right end of any horizontal line “connects” with the left end of the line below it. Each line represents 15 minutes of data; four lines per hour.

How do you make a simple seismograph?

Stand the box up on one of the smaller sides. Carefully poke two holes opposite from each other near the rim of the cup. Tie a piece of string (slightly longer than the length of the box) to each hole. Carefully poke two holes in the top of the box (make them the same distance apart as the holes in the cup).

How do you read a seismograph?

What’s the difference between seismograph and seismoscope?

As nouns the difference between seismograph and seismoscope is that seismograph is an instrument that automatically detects and records the intensity, direction and duration of earthquakes and similar events while seismoscope is an instrument that indicates the occurrence of an earthquake.
