Would an earthquake be more severe if it had a higher or lower magnitude?
An earthquake with a higher magnitude would generally be more severe. Magnitude measures the amount of energy released by an earthquake, so a higher magnitude indicates a stronger earthquake with more potential to cause damage. However, the severity also depends on other factors including the depth of the earthquake, population density, and building infrastructure in the affected area.
How is the amount of energy released by an earthquake measured?
The energy released by an earthquake is measured using a seismometer. The amplitude of the seismic waves recorded by a seismometer are in-turn plugged into an equation that gives a value on the magnitude scale.
Is the epicenter the place where the strongest vibrations are felt?
The epicenter of an earthquake is the point on the Earth's surface above the focus or hypocenter which is the point within the Earth where the rupture occurs. As such the epicentre is the closest point to this and the seismic waves have had to travel through the smallest amount of material and so have undergone the least amount of attenuation (in this case attenuation is a reduction in amplitude of the seismic waves due to energy being lost by their movement or propagation through the Earth). However there can be some exceptions to this and please see the related questions for more information.

What are some facts about earthquakes?
1. Most earthquakes take place in well defined zones at transform, divergent and convergent plate boundaries. 2. An earthquake epicenter is found by analysing earthquake waves at no fewer than 3 seismic stations. 3. The Richter Magnitude Scale and Moment Magnitude Scale are used to express the amount of energy released during an earthquake. 4. The elastic rebound theory is used to explain how energy is released during an earthquake. 5. Seismology is the study of earthquakes. 6. 80% of earthquakes occur within the Circum-Pacific belt, or the Pacific Ring of Fire. 7. The Indian Ocean earthquake which occurred on Dec 26, 2004 was the result of a 9.0 magnitude earthquake which occurred in the Indian Ocean, killing over 160,000 people. 8. A seismograph is an instrument that detects, records and measures the vibrations produced by an earthquake. 9. The epicenter is not where the earthquake actually began but the point on the earth's surface directly above it. The location at which the earthquake started is actually called the focus. 10. More than 150 000 earthquakes are felt every year. 11. 900 000 earthquakes are recorded every year but many are too small to be felt. 12. An earthquake generates two types of waves, Body waves and Surface waves. 13. The arrival times of the different types of Body waves allow seismologists to find the epicenter. 14. An aftershock is an earthquake that occurs after the main earthquake. 15. Sometimes the aftershock can be larger then the initial quake.
What affects the amount of destruction caused by earthquake vibration?
the building designs,the distance from the epicenter,and the type of surface material (rock or dirt) the buildings rest on

How does an area's distance from the epicenter effect the amount of damage an earthquake will do?
The proximity of the epicentre to populated or urban areas will effect the damage caused as the closer the earthquake's epicentre, the more energy will be retained by the earthquake waves and so the greater their capacity to cause damage.
What are two factors that can determine the amount of destruction that results from an earthquake?
the magnitude and the lacation of the epicenter.
Is the depth of focus an important factor in determining the intensity of an earthquake?
Yes. The deeper the focus of an earthquake, the less intense the shaking is due to there being a larger amount of rock between the focus and the epicenter.
Why is magnitude a better measure of strength of earthquakes than intensity?
The difference is that intensity is the extent of damage released by an earthquake and is measured differently at different places depending on its distance from the epicenter while the magnitude is the amount of energy released by an earthquake and it has a fixed energy as it is released by an earthquake.
How is the amount of energy released from an earthquake related to its magnitude?

An earthquake with a higher magnitude would generally be more severe. Magnitude measures the amount of energy released by an earthquake, so a higher magnitude indicates a stronger earthquake with more potential to cause damage. However, the severity also depends on other factors including the depth of the earthquake, population density, and building infrastructure in the affected area.
How is the magnitude of an earthquake related to its destructive effects?
Broadly speaking, the amount of damage an earthquake causes will increase as it's magnitude increases. For more information on this topic, please see the related questions.
Can you explain how the transfer of energy as seismic waves is related to the frequency and magnitude of earthquake in a region?
They both based on the amount of energy that is released during earthquake
Where do people first feel the ground shaking during an earthquake?
The strongest shaking is towards the center of the actual earthquake which it is called the focus. The epicenter of an earthquake is the point on the Earth's surface above the focus or hypocenter which is the point within the Earth where the rupture occurs. As such the epicenter is the closest point to this and the seismic waves have had to travel through the smallest amount of material and so have undergone the least amount of attenuation (in this case attenuation is a reduction in amplitude of the seismic waves due to energy being by moving through the Earth). However as with a lot of things in Earth sciences there can be exceptions to this! This is because the amplitude of seismic waves is affected by the density (related to the level of compaction in the case of soils) of the material through which it is traveling). So a seismic wave traveling through a hard rock such as granite will have a much lower amplitude than one traveling through a softer, less dense, poorly compacted material such as a soil and so due to the higher amplitude there will be a higher level of perceived and measurable ground shaking, even an equal distances from the epicenter.
How is the amount of energy released by an earthquake measured?
The energy released by an earthquake is measured using a seismometer. The amplitude of the seismic waves recorded by a seismometer are in-turn plugged into an equation that gives a value on the magnitude scale.
