How do earthquakes get measured?
Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.
What is more accurate than the Richter scale?
A quake registering as 7.0 on the Richter scale is 10,000 times more powerful than a 3.0. Richter isn’t the only game in town: developed around the same time, the Mercalli Scale gives us a more accurate understanding of how an earthquake actually felt on the surface of the earth by rating it from I to XII.
What does the Mercalli Scale measure?
The Mercalli Scale is based on observable earthquake damage. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. For example a level I-V on the Mercalli scale would represent a small amount of observable damage.
Which is better Mercalli scale or Richter scale?
The Mercalli scale is linear and the Richter scale is logarithmic. i.e. a magnitude 5 earthquake is ten times as intense as a magnitude 4 earthquake….Comparison chart.

What can the Richter scale tell us about an earthquake?
The Richter scale measures the magnitude of an earthquake’s largest jolt of energy . This is determined by using the height of the waves recorded on a seismograph. The Richter scale is logarithmic. The magnitudes jump from one level to the next.
Is the Richter scale the best way to measure earthquakes?
An earthquake is usually considered much more serious, and is felt by most people, once it hits about 5.0. Each number of the Richter scale is equal to a ten-fold increase in the magnitude of an earthquake. In other words, an earthquake measuring 6.0 on this scale has a magnitude ten times greater than a 5.0 quake.
How is the Richter scale used to compare earthquakes?
The Richter scale is used to rate the magnitude of an earthquake — the amount of energy it released. This is calculated using information gathered by a seismograph. The Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude.
What is earthquake ranked the highest on the Richter scale?
Based on the Richter scale, the strongest earthquake ever recorded reached a magnitude of 9.5 out of 10, the highest ever documented. According to Statista, an earthquake with a magnitude of 9.0 or higher is defined as “causing near or at total destruction, causing severe damage to or the collapse of all buildings.”
