There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
a seismometer is used to dectect when a earthquake it prdicted to happen some people call the an instument

A Richter Scale is used to measure Earthquakes and the power of earthquakes. The number used is ten times greater in force than the one before it, so a 7.0 Earthquake is ten times more powerful than a 6.0, for example.

Earthquakes are measured by a seismometer, also known as a seismograph.
You mean a seismograph =)........A seismograph is a instrument that measures motions of the ground.They are usually used to detect earthquakes and volcanic eruptions.
It does not appear that vibration testing is being used to detect earthquakes. Scientists have been using accelerometers built in computers to help them detect upcoming earthquakes.

A seismograph is an instrument used to record vibrations in or on a planet.
An electroscope is an instrument used to detect static electricity.
