What are the 3 faults that cause earthquakes?
Earthquakes occur on faults - strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on reverse or thrust faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.What are the 3 major types of faults?
Different types of faults include: normal (extensional) faults; reverse or thrust (compressional) faults; and strike-slip (shearing) faults.What is the 3 main cause of earthquakes?
In general, the earthquakes that we experience are called naturally occurring earthquakes and the causes for these earthquakes can also be divided into: 1) tectonic earthquakes, 2) volcanic earthquakes, and 3) impacting earthquakes (such as those caused by the impact of meteorites).What are the 3 main effects of earthquakes?
Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis. The extent of destruction and harm caused by an earthquake depends on: magnitude. intensity and duration.Earthquake Faults—3 basic types...in brief (educational)
What 3 factors affect the earthquake?
Factors that Affect the Impact of an Earthquake
- Severity. Some earthquakes are just bigger than others. ...
- Distance. Earthquake intensity is affected by both the distance along the surface of the Earth and how deep the earthquake is below the Earth. ...
- Population Density. Another big deal is population density.
What are the three 3 types of earthquake?
There are many different types of earthquakes: tectonic, volcanic, and explosion. The type of earthquake depends on the region where it occurs and the geological make-up of that region. The most common are tectonic earthquakes.What are the 3 worst earthquakes?
Biggest Earthquakes ever recorded
- Valdivia, Chile 22 May 1960 (magnitude 9.5) ...
- Prince William Sound, Alaska 28 March 1964 (magnitude 9.2) ...
- Sumatra, Indonesia 26 December 2004 (magnitude 9.1) ...

What are the 3 most common stresses that cause earthquakes?
There are three types of stress: tensional, compressional, and shear. Tensional stress involves forces pulling in opposite directions, which results in strain that stretches and thins rock. Compressional stress involves forces pushing together, and compressional strain shows up as rock folding and thickening.What is the #1 cause of earthquakes?
Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.How do earthquakes happen?
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.What are the three 3 basic circuit faults?
There are mainly three types namely line to ground (L-G), line to line (L-L), and double line to ground (LL-G) faults. The line to ground fault (L-G) is the most common fault and 65-70 percent of faults are of this type. It causes the conductor to make contact with the earth or ground.What causes fault lines?
Normal faults cracks where one mass of rock slides downward and pulls away from another mass of rock. As these plates are slowly splitting apart and pulling away from each other the normal faults are formed in this way. Normal faults are associated with downward movement on a sloping fault as the two plates move apart.What are the 3 types of faults?
The 3 types of faults are:
- Normal faults.
- Reverse faults.
- Strike-slip faults.
What are the 3 types of stress fault earthquake?
There are three types of stress that can form along a fault:
- Compressional stress - occurs when two blocks of rock push toward one another.
- Shear stress - occurs when two blocks of rock slide past one another.
- Tensional stress - occurs when two blocks of rock move away from one another.
