The First Earthquake Detectors The first known earthquake detector was invented in 132 A.D. by the Chinese astronomer and mathematician Chang Heng. He called it an “earthquake weathercock.” Each of the eight dragons had a bronze ball in its mouth.
Where was the first earthquake detector invented?
China
You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng.
When was earthquakes first discovered?
The earliest earthquake for which we have descriptive information occurred in China in 1177 B.C. The Chinese earthquake catalog describes several dozen large earthquakes in China during the next few thousand years.
When was the first seismographic station was installed?
On January 1, 1961, station KHC officially began recording seismic data via a 3-component short period seismometer—one vertical and two horizontal, according to Kolář (Figure 2). Over time, the station became known for both careful processing by the scientists and for the low-level noise.
Who invented earthquake detectors?
Zhang Heng
Then: replica of Zhang Heng’s seismographNearly 2,000 years ago, in 132, a Chinese scientist named Zhang Heng invented the world’s first seismograph, an instrument to detect earthquakes.
Who invented the earthquake detecting tool?
philosopher Chang Heng
The earliest seismoscope was invented by the Chinese philosopher Chang Heng in A.D. 132. This was a large urn on the outside of which were eight dragon heads facing the eight principal directions of the compass.

Who invented the earthquake detector?
Who started seismology?
The science of seismology was born about 100 yr ago (1889) when the first te- leseismic record was identified by Ernst yon Rebeur-Pasebwitz at Potsdam, and the prototype of the modern seismograph was developed by John Milne and his associates in Japan.
Where was the first seismograph installed in the United States in 1897?
the Lick Observatory
In 1897, the first seismograph was installed in the United States, near San Francisco at the Lick Observatory. This seismograph was able to record the great San Francisco earthquake of 1906, allowing for further study of this massive event.
Where was the first Jesuit seismographic station installed?
the Observatory of Manila
The first seismographic station installed by Jesuits was about 1868 in the Observatory of Manila.
Why is Zhang Heng famous?
Zhang Heng (78–139 CE) was a Chinese astronomer and inventor. He was the chief astronomer in the court of the Chinese Emperor and mapped the stars and planets. He correctly recognized that the moon was not a light source, but reflected the light of the Sun, a controversial suggestion at the time.

What was Zhang Heng famous for?
Zhang Heng, Wade-Giles romanization Chang Heng, (born 78 ce—died 139), Chinese mathematician, astronomer, and geographer. His seismoscope for registering earthquakes was apparently cylindrical in shape, with eight dragons’ heads arranged around its upper circumference, each with a ball in its mouth.
Who was the scientist who discovered the seismic waves in 1885?
Augustus Edward Hough Love, (born April 17, 1863, Weston-super-Mare, Somerset, England—died June 5, 1940, Oxford), British geophysicist and mathematician who discovered a major type of seismic wave that was subsequently named for him.
Who is best seismologist in the world?
The Earth Sciences professor emerita was recently awarded the Harry Fielding Reid Medal by the Seismological Society of America for her lengthy career as one of the world’s most revered seismologists.
How long have scientists been studying earthquakes?
At present seismology is the study of seismic sources (mostly earthquakes), the waves they produce, and the properties of the media through which these waves travel. In its modern form the subject is just over 100 years old, but attempts to understand earthquakes go back to the beginnings of science.
What are the contribution of Jesuits?
The Jesuit order played an important role in the Counter-Reformation and eventually succeeded in converting millions around the world to Catholicism. The Jesuit movement was founded by Ignatius de Loyola, a Spanish soldier turned priest, in August 1534.
