The seismograph was created by Zhang Heng, an ancient Chinese polymath, around 132 AD. His invention was able to detect and measure earthquakes, making it a groundbreaking development in the field of seismology.
The tracing of an earthquake motion created by a seismograph is known as a seismogram. It represents the ground motion recorded by the seismograph during an earthquake, displaying the amplitude and duration of seismic waves. Seismologists use seismograms to determine the magnitude, location, and depth of an earthquake.
The first modern seismograph was created by John Milne, a British seismologist, in the late 19th century. Milne's design allowed for the accurate recording of seismic waves and greatly advanced the study of earthquakes.
A seismogram traces the earthquakes motion that is created by the seismograph and the seismograph records vibrations in the ground and determines the location and strength of an earthquake.
Seismograph showed 7.0 on the scale. It is an instruments for measuring earthquakes.
It was created during the Han Dynasty in China....

what is the market value for seismograph
seismograph is called 'bhukamplekhi' in hindi
the purpose of the seismograph is that it tells you when a earthquake is coming. :)
Humorous answer: A seismograph never answers; it just waves.
