Which depth range has the most earthquakes and the fewest earthquakes?
Most earthquakes occur at a depth of between 13-18 km. This is the Brittle-Ductile Transition zone and marks the strongest part of Earth's crust. The depth of the focus can be categorized as shallow, up to 70 km below the surface, or deep which is greater than 300 km. The fewest earthquakes have a depth range greater than 70 km.
What general depth of focus earthquakes are likely to occur in himalaya?

A shallow earthquake occurs less than km below earth's surface?
Earthquakes occurring at a depth of less than 70 km are classified as 'shallow-focus' earthquakes, while those with a focal-depth between 70 and 300 km are commonly termed 'mid-focus' or 'intermediate-depth' earthquake.
Is the absence of deep focus earthquakes along the oceanic ridge system is inconsistent with the theory of plate tectonics?
No, the crust is very thin under the oceanic ridge system, making deep focus earthquakes impossible there as the crust does not have the required depth for such earthquakes.
True or false earthquakes get shallower in the direction of subduction?
False. As the subducted slab descends into the mantle, the focal depth increases.
Explain the classification scale used to describe the depth of origin of earthquakes?
Shallow focus (0-70km), intermediate focus (70-300km), and deep focus (greater than 300km)
What are South America describe the pattern of Earthquake depth from west to east along line AB?
Towards the west, earthquakes are shallow. But, as you go to the east you can see that the earthquakes proceed to deeper.

Why do earthquakes occur at depth less than 100 km?

A shallow earthquake occurs less than km below earth's surface?
Earthquakes occurring at a depth of less than 70 km are classified as 'shallow-focus' earthquakes, while those with a focal-depth between 70 and 300 km are commonly termed 'mid-focus' or 'intermediate-depth' earthquake.
What is the relationship between the strength of earthquakes and how often it occurs?
Friction is overcome when the accumulating stress has enough force to ... About 90% of all earthquakes occur at a depth between 0 and 100 kilometers.
Do deep earthquakes refer to earthquakes deeper than 700 km?
No, the rocks in the earth at that depth are too rigid and plastic-like to store the amount of stress needed for an earthquake to occur.
What occurs along ocean trenches but not along mid ocean ridges that accounts for the occurrence's of deep focus earthquakes?
Subduction of oceanic crust. The Earthquakes occur at depth in the descending slab.
What was the biggest recorded earthquakes?
i think it was this earthquake..Valdivia, Chile1960 Valdivia earthquake it had 6,000 causalities and was 33km in depth
