What does a 1.0 increase on the Richter scale mean?
It means that the maximum amplitude of the seismic waves recorded is 10 times bigger for every 1.0 increase. This is equivalent to a 32 times increase in the amount of energy released by the earthquake.
What does the number assigned to an earthquake mean?
It indicates the amount of energy released during the earthquake. It is a logarithmic scale, meaning (in this case) that 1 number more on this scale indicates 10 times more energy, 2 more indicates 100 times more energy, etc.
What does the frequency of an earthquake mean?
The frequency of an earthquake refers to how often earthquakes of a given magnitude occur in a particular region over a period of time. It helps to understand the seismic activity and the likelihood of future earthquakes. A higher frequency indicates more frequent seismic events in that area.
How much stronger is 6.6 earthquake than an 8.3 earthquake?
An 8.3 earthquake is significantly stronger than a 6.6 earthquake. Each whole number increase on the Richter scale represents a tenfold increase in the amplitude of seismic waves, meaning an 8.3 earthquake releases exponentially more energy than a 6.6 earthquake.
What do you called seintist an earthquake?
A scientist who studies earthquakes is called a seismologist. They analyze seismic waves and tectonic activity to better understand the causes and effects of earthquakes. Their work helps in earthquake prediction and mitigation efforts.

How do you understand what all the squiggly lines on a seismogram mean?
A seismogram records the ground movement caused by seismic waves from an earthquake. The squiggly lines represent the waves' amplitude and frequency. By analyzing these changes, seismologists can determine the earthquake's magnitude, location, and depth.
The earthquake which struck Haiti was recorded as magnitude 7.0 what does this mean?
Magnitude is a term used to describe how much energy was released by an earthquake. It gives an indication of the amplitude of the seismic waves that occur and also on the length of the fault rupture zone and the displacement along the fault. A magnitude 7 earthquake is defined by the US Geological Survey as a "major" earthquake. In general earthquake over a magnitude of 4 or 5 can cause damage although the exact reasons why some earthquake are more damaging than others is more complext than just the absolute magnitdue of the earthquake. For more information on this, see the related question.
How much greater is a magnitude 7.0 earthquake than in comparison to a 6.0 earthquake?
My understanding of the magnitudes of earthquakes is that each decimal point is equal to a magnitude of strength 10x more than the previous number. Example would be that a 4.2 earthquake is 10x stronger than a 4.1 earthquake. Therefore, a magnitude 8.5 EQ is 100x stronger than a 7.5 EQ.
What are the back and forth movement caused by earthquake?
The back and forth movement caused by an earthquake is known as seismic waves. These waves travel through the Earth's crust, creating the shaking effect that we feel during an earthquake. The type of seismic waves produced can vary depending on factors such as the type of fault movement that generated the earthquake.

Why is 6.0 magnitude earthquake so much more destructive than a 5.0 magnitude earthquake?
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.

What does seismic mean?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.

The frequency of an earthquake refers to how often earthquakes of a given magnitude occur in a particular region over a period of time. It helps to understand the seismic activity and the likelihood of future earthquakes. A higher frequency indicates more frequent seismic events in that area.
Why is the intensity value of an earthquake more meaningful than magnitude to a nonscientist?
The strength (more correctly termed magnitude) of an earthquake is a measurement of the energy released when the earthquake occurs. The intensity however is derived based on the perceived level of ground shaking at a specific location and is a function of the amplitude of seismic waves at a given point and the damage they cause. The damage caused is in turn related to the local ground conditions and the specific construction techniques followed in the area. Therefore for earthquakes of equal magnitudes, the location of the earthquake's epicentre in relation to centres of population is important. A high magnitude earthquake that occurs far from a populated area will do less damage than an lower magnitude earthquake in very close proximity to a populated area. As such the earthquake would have a lower magnitude but a higher intensity. Secondly, ground motion and the amplitude of seismic waves is strongly dependent on the medium through which they travel. Seismic waves in hard rock masses (e.g. granite) have lower amplitudes than those that travel through soft ground such as sediments and so a building constructed and founded on hard rock is less likely to be damaged. As such a lower magnitude earthquake affecting structures founded on softer sediments may ultimately cause more damage than a higher magnitude earthquake affecting structures founded on hard rock. Again this would mean that in this specific case the earthquake of equal or lower magnitude would have a potentially greater effect on structures founded on soft soils and so the the intensity would be higher. For more information, please see the related question.
What is magaitude?
You might mean Magnitude magnitude is the measure of energy released in an earthquake. it doesnt change per area like intensity, an earthquake has one magnitude. It may be expressed using several magnitude scales. It is very unlikely that an earthquake of magnitude less than 5 could cause any damage.
