Who invented the Seismometer?

Answer 1

The seismograph was not discovered, it was invented in 132 CE by Zhang Heng, but most modern seismographs are derived from a design by John Milne, James Alfred Ewing, and Thomas Gray, who worked in the late 19th century.

Answer 2

The main problem that had to be solved in creating the seismograph is that when the ground shook, so did the instrument. Therefore, in making seismographs they had involve a large mass of some sort.

You could make a very simple seismograph by hanging a large weight from a rope over a table. By attaching a pen to the weight and taping a piece of paper to the table so that the pen can draw on the paper, you could record tremors in the Earth's crust (earthquakes). If you used a roll of paper and a motor that slowly pulled the paper across the table, you would be able to record tremors over time. However, it would take a pretty large tremor for you to see anything.

In a real seismograph, levers or electronics are used to magnify the signal so that very small tremors are detectable. A big mechanical seismograph may have a weight attached that weighs 1,000 pounds (450 kg) or more, and it drives a set of levers that significantly magnify the pen's motion.

Answer 3

the seismograph was made by Chang Heng. He invented the seismograph 132 A.D.

Answer 4

actually somebody did it was somebody i don't Know really
