historians believe there was a pendulum inside and when an earthquake hit, the pendulum swung causing it to hit a lever which would cause a dragon facing the direction of the quake to drop its copper ball into the mouth of a toad below
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.
The seismograph was invented during the Han Dynasty in ancient China. Specifically, it was created around 132 AD by the polymath Zhang Heng. This early seismograph, known as the "Houfeng Didong Yi," was designed to detect and indicate the direction of earthquakes. It marked a significant advancement in the understanding of seismic activity in ancient times.
In ancient times, seismographs did not exist as we know them today. The first recorded seismoscope was created by the Chinese philosopher Zhang Heng in 132 AD, but there is no information available on its cost.
The earliest tool for measuring earthquakes was invented by Chinese astronomer Zhang Heng in 132 AD. He created the world's first seismoscope, a device that could detect the direction of an earthquake and the magnitude of its tremors.
Seismometers. For information on how seismometers are used, please see the related question.
John Milne invented the first modern seismograph, but the first ones were invented by Chang Heng around 132 AD.
Hsieh Chang-heng was born in 1962.
Zhang Heng invented the seismograph to detect and measure earthquakes. He was motivated by a desire to protect people from the dangers of earthquakes by providing advance warning, allowing them to prepare and seek safety. His invention was a significant advancement in early earthquake detection and monitoring.
Yes, Choko did not invent the seismograph. The seismograph was invented by the Chinese polymath Zhang Heng in 132 AD during the Han Dynasty. Zhang Heng's seismograph could detect and record earthquakes from a distance.
The seismograph was invented by the Chinese polymath Zhang Heng in 132 AD during the Han dynasty. Zhang Heng's seismoscope was an early version of today's seismograph, used to detect and measure earthquakes.
Yes, the Chinese are credited with inventing the seismograph. It was created by the Chinese polymath Zhang Heng in 132 AD during the Han dynasty. The device could detect the direction of an earthquake and inspired the development of modern seismographs.
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.
Zhang Heng invented the first seismograph and also remade the calender so that the seasons were aligned.

The chinese inventor Zhang Heng. Pernounced: Jun Hun
The first "modern" seismograph was invented by John Milne in 1880. However, Zhang Heng, a Chinese astronomer is also believed to have invented the seismograph; probably the primitive ones.
