A person named Zhang Heng is known to be the first to make a prototype of it. He came from China back in 132 AD.
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 seismograph is a device that measures and records seismic waves caused by earthquakes, while a seismogram is the record of the data produced by a seismograph. Together, they are essential tools in studying and monitoring earthquakes and other seismic activities around the world.
The first seismograph was invented in China by Zhang Heng in 132 AD. It worked using a pendulum mechanism where a suspended pendulum would swing in response to ground motion caused by an earthquake, triggering a mechanism that would drop a ball into one of eight dragon mouths, indicating the direction of the quake.
It was invented in china in ancient tokyo by your mother
A seismometer (or the older device called a seismograph) records the seismic waves from earth tremors.+++There is a difference there: a seismometer would simply register instant vibration; a seismograph records the vibrations with time so shows the whole picture.
First
The first seismograph was invented in 132 AD by Chinese astronomer Zhang Heng during the Han dynasty. It was a copper vessel with a pendulum mechanism that could detect and record earthquakes.
1898
P-waves are the first seismic waves to arrive at a seismograph station.
John Milne invented the seismograph in Tokyo, Japan in the late 19th century. He installed the first modern seismograph at the Imperial University of Tokyo in 1880.

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.
Europeans began using the seismograph in the 19th century, with the first seismograph being invented in 1880 by John Milne in England. The seismograph revolutionized the study of earthquakes by providing a way to measure and record seismic activity.
The seismograph station closest to the earthquake epicenter would have recorded P-waves first, followed by stations farther away. Since P-waves are the fastest seismic waves, they are the first to arrive at a seismograph station after an earthquake.
The first seismograph was invented by Zhang Heng in 132. The modern seismograph was invented by John Milne, Thomas Gray, and James Alfred Ewing in 1880.
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.
Here are some sentences.Scientists use a seismograph to measure movement in the earth.The seismograph showed that an earthquake had occurred.
