The instruments are seismographs or seismometers.
A seismograph is used to measure earthquakes.
Richter magnitude scale-
The most common instrument (tool) is a tape measure.
They use a seismograph
Seismograph
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.
I would use the odometer on my car. If that does not help I would use a map and a ruler and measure it to scale.

a seismograph is used to measure intensity of earthquake
they have a special tool that they use to measure the intensness of the earthquake 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.

Ruler.
its called richter scale and a mercalli scale
There are a few instruments that can theoretically be used to measure flour. The most common measuring tool is a measuring cup.
Burett
I think that the most commonly used tool to measure the height of a cube is an everyday ruler.
the tool used to measure a area is a tape measure
Rulers, tape measures, calipers.
the mass measuring tools are: standard balance senstive balance and there are lot more types
