∙ 14y agoLess than 2.0- Micro, Microearthquakes, not felt.
2.0-2.9- Minor, Generally not felt, but recorded
3.0-3.9- Minor, Often felt, but rarely causes damage.
4.0-4.9- Light, Noticeable shaking of indoor items, rattling noises. Significant damage unlikely.
5.0-5.9- Moderate, Can cause major damage to poorly constructed buildings over small regions. At most slight damage to well-designed buildings.
6.0-6.9- Strong, Can be destructive in areas up to about 160 kilometres (100 mi) across in populated areas.
7.0-7.9- Major, Can cause serious damage over larger areas.
8.0-8.9- Great, Can cause serious damage in areas several hundred miles across.
9.0-9.9- Great, Devastating in areas several thousand miles across.
10.0+- Epic, Never recorded

∙ 13y agoIn general the smaller the magnitude the greater the number of earthquakes. However once they become smaller in magnitude than around 4.0 the detected number of earthquakes begins to decrease as for obvious reasons, the smaller the earthquake, the more difficult it is to detect, this however doesn't mean that less are occurring!

What it measured on the Richter scale?
Richter scale measures the magnitude of earthquakes.
Which is not a factor in calculating the moment magnitude of an earthquake?
magnitude of past earthquakes in the area
What is the relationship between intensity and magnitude of an and earthquake?
the relationship between earthquakes magnitude is the size or amount of energy an earthquake produces and has no connection to hour often earthquakes occur.
What is the highest magnitude in history of earthquakes?
The highest magnitude earthquake was a 9.5 in Chile on May 22, 1960.
Why don't moderate earthquakes decrease the chances of major quake in the same region?
A magnitude 7 releases about 1000 times more energy than a magnitude 5, so therefore you need 1000 magnitude 5 earthquakes to release the same energy as 1 magnitude 7.
What is the magnitude range for small earthquakes?
Probably under 4 or 5.
What are high magnitude earthquakes?
earthquakes with high magnitude.
Why are there fewer magnitude 2 and 3 earthquakes instead of magnitude 4 earthquakes?
There are far more magnitude 2 or 3 earthquakes than magnitude 4 earthquakes. The small quakes just don't get noticed as much because they typically do little or no serious damage.
What does magnitude have to do with earthquakes?
The word magnitude (in the context of earthquakes) is used to describe the amount of energy released when one occurs.
How high can an earthquake's magnitude go?
An earthquake's magnitude can go as high as 10 or above on the Richter scale. Magnitude 10 earthquakes are extremely rare and are considered to be the strongest earthquakes ever recorded. The majority of earthquakes are of lower magnitude, with the average being around magnitude 4.
What number on the Richter scale do most earthquakes fall?
Most earthquakes are classified as "microquakes" that fall in the range of 1.0 to 1.9 on the Richter scale. Several million such quakes occur each year - practically continuously. A bit over one million quakes a year fall in the range from 2.0 to 2.9 on the Richter scale. A bit over 100,000 quakes with a magnitude of 3.0 to 3.9 occur each year Light earthquakes in the range from 4.0 to 4.9 happen about 10,000 to 15,000 times each year. About 1,000 to 1,500 moderate earthquakes in the range of 5.0 to 5.9 shake things up each year. Strong earthquakes (in the range of 6.0 to 6.9) hit 100 to 150 locations on the earth each year. We get 10-20 major earthquakes (magnitude 7.0-7.9) each year. An earthquakes in the range from 8.0 to 8.9 might occur once a year somewhere on the earth. Earthquakes of magnitude 9.0 or greater only occur once every 10 to 50 years.
Has New York had an earthquake?
New York has had 16 earthquakes with magnitude range of 3.5 and greater from 1974-2003. And the largest earthquake in New York was magnitude 5.8 on May 9, 1944.
Do all earthquakes have after shock?
No only middle and big magnitude earthquakes do.
How is an earthquakes energy measured?
Magnitude
How is the moment magnitude used to describe earthquakes?
The moment magnitude scale can be used to rate earthquakes of all sizes, near or far.
How may earthquakes of 6 or more magnitude occur each year?
There's about 140 earthquakes with 6 magnitude or above a year.
Which is a factor in calculating the moment magnitude of an earthquake?
magnitude of past earthquakes in the area
