# Why is the mercalli scale in Roman numerals?

So that it isn't confused with the Richtes Scale, probably.

### What factors determine an earthquake's intensity on the modified mercalli scale?

The Modified Mercalli Intensity scale is used in the US to determine the severity of earthquake effects. Intensity ratings are in Roman numerals, I - meaning no people felt movement, all the way up to XII - where almost everything is destroyed. The amount of structural and geological damage done by an earthquake in a specific location determines an earthquake's intensity on the Mercalli scale. :)

### What is the Mercalli scale?

== The mercalli scale also known as the Modified Mercalli Intensity (MMI) scale is a measure of the ground shaking from earthquakes. It is based on how people perceive earthquake shaking and/or the damage caused by an earthquake. Modified Mercalli Intensity is measured at individual locations so one earthquake can have many different measures of MMI. MMI is measured on a scale of 1 to 12 (actually Roman numerals) with 1 corresponding to the slightest…

### What measurement is used to determine the strength of an earthquake?

There are 2 ways. Richter scale. This is an objective method, and is a scale of 1-10, each 0.1 increase in size is a 10 fold increase in power. (it is only possible, even with a mega-thrust quake to reach 9 on the Richter scale). This is the most accurate and commonly used scale Mercalli Scale. This is a subjective scale, and the reading is based on the damage done by the earthquake. It is…

### How does the Richter scale best demonstrate the power and the destructive nature of an earthquake?

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.Richter ratings only give you a rough idea of the actual impact of an earthquake, though. As we've seen, an earthquake's destructive power varies depending on the composition of the ground in an area and the design and placement of man-made structures. The extent of damage is rated…
