Why might a magnitude 7 earthquake have less intensity than a magnitude 6 earthquake?
There are many factors. One would be the distance a person is from the epicenter. A person who is further from a magnitude 7 earthquake would be less affected by the shockwaves than a person nearer to the epicenter of a magnitude 6 earthquake. The place the person is in at the time of the earthquake also may affect the intensity of what he feels. If one is in a tall and stable building during an earthquake, he would not feel the vibrations as much as one standing on the streets. The scale measuring the intensity of earthquakes should be considered too. A Mercalli Intensity Scale measuring magnitude 6 may possibly be more powerful than a Richter Scale measuring a magnitude 7, as more damage is caused.
What are the levels of an earthquake?
Earthquakes are classified based on their magnitude, which measures the energy released at the source. The Richter scale is commonly used to measure smaller earthquakes, while the moment magnitude scale is used for larger ones. Earthquake intensity, on the other hand, measures the effects of an earthquake on the Earth's surface and is usually described using the Modified Mercalli Intensity (MMI) scale.
How strong is a magnitude 8 earthquake compared to a 7?
A magnitude 8 earthquake is 10 times stronger than a magnitude 7 earthquake in terms of energy released. The shaking and potential damage caused by a magnitude 8 earthquake would be significantly greater than that of a magnitude 7 earthquake.
How many times more powerful is an earthquake measuring 7.0 than one measuring 5.0?
The Richter magniude scale is logorithmic. As such the size (amplitude) of the largest seismic waves produced by a magnitude 7 earthquake are 102 (or 100) times larger than those produced by a magnitude 5 earthquake. However the amount of energy released by a magnitude7 earthquake is 1000 times greater (102)^3/2 than a magnitude 5 earthquake and so it is likely to be much more destructive.
How does the strength of an earthquake change as you go up the Richter scale?
The strength of an earthquake increases exponentially as you go up the Richter scale. For each whole number increase on the Richter scale, the amplitude of ground motion and energy release increases by about tenfold. So, a magnitude 6 earthquake is 10 times stronger than a magnitude 5 earthquake, and a magnitude 7 earthquake is 100 times stronger than a magnitude 5 earthquake.
What is the relationship between depth of focus and earthquake intensity?

What was the intensity level of the Great Lisbon earthquake in 1755?
Modern geologists estimate that the 1755 earthquake reached 9 points in the Richter scale (the Haiti earthquake was 7 points). The earthquake was followed by a massive tsunami of 5 meters (15ft) high, and several fires that destroyed Lisbon almost to the ground. check related links for more information.

What scale is used to measure earthquake intensity?
The moment magnitude scale is used to measure the magnitude of large earthquakes. The Richter scale is still used to make an initial estimate of the magnitude of larger earthquakes and to measure small and moderate ones (those with a magnitude below 7).
What words are used to describe an earthquake of magnitude 5 to 7?
That would be a "kind of strong" earthquake but 8+ is huge.
Was there a earthquake in Hollister California on December 5th 2014?
On December 5, 2014 there was an earthquake approximately 7 miles west-southwest of Hollister. The magnitude was 3.9.
How much more powerful is a 9.0 earthquake and a 7.0 earthquake?
A 9.0 earthquake is 1,000 times more powerful than a 7.0 earthquake in terms of energy release. This difference results in significantly greater damage potential, as the intensity of shaking and the area affected also increase with the magnitude.
What are three prime numbers less than 20 hat differ by 2?
They are: 3, 5 and 7
What are the two primes that differ from 2?
There are infinitely many twin primes. One example is 5 and 7.
What was the Fukushima earthquake's intensity?
The U.S. Geological Survey (USGS) Earthquake Center said the March 11, 2011 magnitude 9.0 earthquake (originally reported as 8.9) was the "biggest quake to hit Japan since record-keeping began in the late 1800s and one of the biggest ever recorded in the world".The official name of the March 2011 Earthquake in Japan is the Tōhoku earthquake, which affected the Tōhoku region and neighboring regions including Fukushima.UPDATE: Official magnitude was updated to 9.1 on Nov 7, 2016Related links:USGS Tōhoku earthquake official record
