SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -The magnitude of an earthquake is measured by an instrument called seismograph.

Detailed explanation-3: -A network of worldwide seismographs detects and measures the strength and duration of the earthquake’s waves. The seismograph produces a digital graphic plotting of the ground motion of the event.

Detailed explanation-4: -A device called a seismograph can be used to measure the magnitude of any earthquake.

Detailed explanation-5: -A seismograph is a scale used for measuring the magnitudes of earthquakes.

Detailed explanation-6: -Seismograph is also known as a seismometer. It is an instrument used in detecting and recording an earthquake. With the help of seismographs scientists detect earthquakes and measure aspects of the event. When an earthquake occurs, the epicenter remains just below the earth surface.
