What is used to find the intesity of earthquakes?
Earthquake intensity is measured on a scale called 'Mercalli Intensity Scale' or more recently 'Modified Mercalli Scale'. The scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and man-made structures on a scale from I (not felt) to XII (total destruction). An earthquake is graded after collecting data from people who have experienced the earthquake and observing the destruction caused by the earthquake. People often confuse 'Intensity' of an earthquake with its 'magnitude.' An earthquake's magnitude is a measure of the energy released by an earthquake that propagates from it. It is measured by the Richter scale(formerly), or Moment Magnitude Scale. Information about the earthquake is put into an algorithm to assign the earthquake to a scale of 2 or less, to 10.0+ and anything in between. A magnitude of 2 or less is extremely weak, and may not have been felt at all. An earthquake with the magnitude of 10 is extremely massive and would cause mass destruction - there have not been any 10.0 earthquakes recorded yet. Magnitude and Intensity are correlated. Intensity depends on the magnitude, distance between focus and surface, and population density of the region etc. So, an earthquake with more magnitude will have more intensity, given all the conditions remain same. See the Related Links section below for the algorithm.
Different shape intensity from magnitude of an earthquake movements?
There are two ways of describing an earthquake;by intensity and by magnitude. When we talk of intensity, we are referring to the effects and damage produced by the earthquake. It is determined by going to all the areas affected by the earthquake and observing the damage, as well as recording the experiences of the people there. The first intensity scale was developed by Giuseppe Mercalli in 1902. This has since been improved by the use of strong motion seismometers which are able to measure ground accelerations and so produce a less subjective assessment of intensity. The value of intensity can vary from place to place. In the US the intensity of an earthquake is measured using the Modified Mercalli scale and in Europe the Macroseismic scale is used (which appears to be an updated version of the original Mercalli intensity scale). Earthquake magnitude on the other hand is a single value (it should be the same no matter where it is measured) and is based on the amount of seismic energy produced by an earthquake. It can be estimated from the amplitude of seismic waves recorded by a seismometer (and requires scaling to account for the distance of the recording station from the earthquakes epicentre) or directly based on the cross sectional area of the fault which moved, the average displacement and the shear modulus of the rockmass. In the past the Richter magnitude scale was commonly used however seismologists now use the Moment magnitude scale. I hope it would help you :)
What is the earthquake measurement?
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.
How would a map showing the locations of active volcanoes compare to the map showing the location of earthquake epicenters?
(a) Only a small percentage of volcano locations would be in the same regions as the epicenters(b) A large percentage of volcano locations would be in the same regions as the epicenter(c) There would be no match between the locations of the volcanoes and the epicenters(d) The location of the volcanoes and the epicenters would only match in the ocean regions
How two locations at the same latitude but different altitude have a different climate?
Ocean and air currents.This is because latitude is only part of what determines a climate.
An earthquake will be given one number on the Richter scale but more than one on the mercalli scale why is this?
The Richter scale measures the strength of an earthquake, this is always the same value, no matter where you are. The Mercalli intensity scale measures the effect of the earthquake on people and structures, and the intensity value will differ depending on how far you are from the epicenter. For instance, a 5.5 magnitude earthquake may be damaging (intensity VII) around the epicenter, but 300 miles away it may be barely felt (intensity II).
How can be determined the earthquake epicenter from seismic waves?
The simplified answer is that it works much in the same way you would determine the source of a sound (which is also in waves). Multiple measurements of the intensity are taken from different locations are used to triangulate an earthquake.
Where is the rating of earthquake damage at a particular location?
You can find the rating of earthquake damage at a particular location on the Modified Mercalli Intensity (MMI) scale, which assesses the intensity of shaking and resulting damage at specific locations. This rating is often provided by organizations like the United States Geological Survey (USGS) or local seismic monitoring agencies in affected areas.
Two different files can have the same name if?
they are in different locations.
Why might an earth quake have more than one intensity value?
Yes. The Mercalli intensity scale measures the effect of the earthquake on people and structures, and the intensity value will differ depending on how far you are from the epicenter. For instance, a 5.5 magnitude earthquake may be damaging (intensity VII) around the epicenter, but 300 miles away it may be barely felt (intensity II). The mercalli scale measures the intensity of an earthquake, where the Richter scale measures the magnitude. Also you have to consider where the earthquake occurred. you can have a 9.0 quake in the middle of the Australian outback but there is hardly anybody there so you would have a low mercalli scale reading. If you had that same quake in San Francisco then you are going to have a seriously high number on the mercalli scale
Is the magnitude of an earthquake same as its intensity?
No.The magnitude is a measure of the total energy released by an earthquake.The intensity is a measure of the violence of ground shaking at a particular point. This is based on the statements of witnesses, damage to buildings and the ground acceleration as measured by a seismometer. As such it varies from place to place for a given earthquake.

Why can the same earthquake on two different scales?
Earthquakes can be measured on different scales because there are different ways to quantify their size and impact. The two commonly used scales are the Richter scale and the moment magnitude scale, which are based on different aspects of the earthquake, such as the amplitude of seismic waves or the total energy released. This is why you may see the same earthquake measured with different magnitudes on different scales.

no there are same color, but the different between them is the intensity of light
