A seismometer is an instrument that records vibrations in the ground caused by earthquakes. It can determine the location and strength of an earthquake by measuring the seismic waves generated by the event.
A seismograph is the instrument used for recording the intensity and duration of an earthquake. It detects and measures the motion and vibrations of the ground caused by seismic waves.
The amount of destruction caused by earthquake vibrations is affected by factors such as the magnitude of the earthquake, the proximity of the earthquake to populated areas, the type of soil and rock present in the region, and the construction standards of buildings and infrastructure.

A seismograph is the graph that shows vibrations caused by an earthquake. It records the movement of the ground in a vertical direction as the seismic waves pass through the Earth's crust.
An instrument used to measure and record ground movements during an earthquake is called a seismometer or seismograph. These devices detect and record the vibrations caused by seismic waves, allowing scientists to analyze the intensity, duration, and characteristics of the earthquake. The data collected helps in understanding earthquake behavior and assessing potential risks.

The sinking of ground caused by earthquake vibrations is called soil liquefaction. It occurs when loose, water-saturated soil temporarily loses its strength and stiffness due to the shaking from an earthquake, causing it to behave like a liquid.
A seismograph is located under the ground. When there is an earthquake, the ground shakes, which also shakes the pen on the seismograph, making it move along the paper, drawing lines. To know how strong the earthquake was, scientist can look on the paper. The bigger the lines, the stronger the earthquake was.
A seismograph is used to record shaking or vibrations in the Earth's crust. It consists of a sensitive instrument that detects ground motion caused by seismic waves during an earthquake. The information recorded by a seismograph helps scientists determine the location, intensity, and duration of an earthquake.
Four factors that affect the amount of destruction caused by earthquake vibrations include the earthquake's magnitude, which determines the energy released; the depth of the earthquake's focus, as shallower quakes tend to cause more surface damage; the distance from populated areas, where closer proximity results in greater destruction; and the local geological conditions, such as soil type and building structures, which can amplify vibrations and influence the level of damage.
The earthquake caused the ground to shake with intense vibrations.
