The first earthquake detector was invented in ancient China during the Han Dynasty (around 132 AD) by the inventor Zhang Heng. This device, called a seismoscope, could detect the direction of distant earthquakes and was remarkably advanced for its time. It predates modern seismographs by nearly 1,700 years.
To answer this question, we need to understand the history of earthquake detection.
The correct answer is C) China.
The first earthquake detector was invented in China. The device, known as the "seismoscope," was created by a Chinese scientist named Zhang Heng during the Han Dynasty around 132 AD. The seismoscope was a bronze vessel with eight dragon heads, each holding a small bronze ball. When an earthquake occurred, the movement of the ground would cause one of the dragon heads to drop the ball into the mouth of a corresponding bronze toad at the base. This would indicate the direction of the earthquake.
Therefore, the correct answer is C) China.
