The instrument is called "seismometer."
The first sacle of measurment for earthquakes is called the richter magnitude scale after its inventor, Charles Richter (in 1935 ), which categorises them in terms obtained by calculating the logarithm of their amplitude.
This scale has been replaced in the 1970s, by the moment magnitude scale which measures the size of earthquakes in terms of the energy released.
The modern scale retains the familiar continuum of magnitude values defined by the older one.

What scale helps you determine the magnitude of an 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. The strongest earthquake that their ever was, was measured a 9.3.
What is the scale to measure earthquake?
Seismometers are used to measure earthquakes waves, this help show the different arrival time between waves. A Richter Scale is used to measure earthquakes strengh, each number is 31 times more powerful than the last. There is no official set number, but no earthquake has hit 10 on the scale.
What kind of scale is the Richter scale based on?
The Richter Scale—more appropriately called the magnitude scale—is one means of expressing the magnitude of an earthquake (i.e., the amount of energy released).
What is the difference between a seismograph and the Richter scale?
Seismic waves are the vibrations from earthquakes that travel through the Earth; they are recorded on instruments called seismographs. Seismographs record a zig-zag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs, which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. The time, locations, and magnitude of an earthquake can be determined from the data recorded by seismograph stations. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
What is an origin of an earthquake called?
The origin of an earthquake is called the epicenter.
What is the tool used to measure the magnitude of an earthquake?
its called richter scale and a mercalli scale
What are the measure of the strength of an earthquake is called?
The Richter magnitude scale is used to measure the strength of an earthquake.
What natural phenomena are measured by the'richer scale'?
the Richter scale is used to measure the power, strength of an earthquake
How do they measure an earthquake how big it is?
It is a device called a seismographe. It is used to determine the magnitude on a scale which is then deciding how bad the earthquake is.
What Instrument measures the density of an earthquake?
The instrument that can measure the density of an earthquake is called an seismometer. The first seismoscope dates back to 132 AD.
How is an earthquake's hazard level determined?
They measure it with a special instrument called seismograph.
What are devises used to know the intensity and magnitude of earthquake?
Those devices are called Seismometer's. They are used to measure seismic shockwaves ( earthquake's)
Define Richter Scale?
- The magnitude of an earthquake can be measured on a scale called Richter scale.- A Richter scale assigns a number each earthquake. This is also known as the Richter magnitude scale.
What is the measurement of an earthquake's strength?
a seismographic flow
What is the strength of an earthquake called?
Magnitude.
What is the amount of energy released by an earthquake called?
This is known as the magnitude of the earthquake.
How do you measure earthquake strength?
Scientists use a machine called a seismometer to measure the strength of an earthquake. The calculated magnitude had been expressed on the Richter scale, a base 10 logarithmic scale, but with a usable limit of 6.5. Currently, magnitude is expressed on the Moment Magnitude Scale.
