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 was the depth of the 1960 Chile earthquake?
The focus of the 9.5 (moment magnitud scale) eartquake of Valdivia 1960 was shallow, 33 km deep.
About 90 percent of continental earthquakes have a shallow?
focus
Which causes more damage a shallow focus or deep focus?
Typically, a shallow focus earthquake will cause more damage than a deep focus earthquake. Shallow focus implies the source of the earthquake is near to the surface, so the waves will lose lesser energy than the deep focus earthquake waves while travelling through the Earth. But it depends on other factors too such as local stratigraphy, and subsurface conditions.
Where do shallow earthquakes occur?
At divergent and transform boundaries.
What is the classification scale used to describe the depth of origin of earthquakes?
shallow focus Intermediate focus Deep focus
What is the maximum depth a deep focus earthquake can occur to?
what is the maximum depth of a deep-focus earthquake
Where do shallow-focus earthquakes occur?
At divergent and transform boundaries.
What is the difference between shallow focus earthquakes and deep focus earthquakes?
Shallow focus earthquakes occur at depths of 70 km with magnitudes ranging from 1-5. Deep focus earthquakes occur at depths from 300-700 km and magnitudes from 6-10.
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 difference between maximum depth of field and shallow depth of field on a camera?
Depth of field in photography is 3-dimensional and is measured from the foreground moving along a horizontal plane towards the background. Maximum depth-of-field means most of the scene is in focus and shallow depth-of-field means the minimum is in focus. Shallow depth-of-field lets you lose the background into a nice blur leaving the foreground in focus - good for portrait photography. In landscape photography you would normally choose the maximum depth-of-field so that distant hills were in focus as well as the middle ground and the foreground - in other words, everything in the field of your vision would be sharply focussed.
Where do shallow-focus earthquakes of the occur relative to ocean trenches?
within or adjacent to trenches
What general depth of focus earthquakes are likely to occur in himalaya?
the darkest niggahhh
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)
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 was the depth of the 1960 Chile earthquake?
The focus of the 9.5 (moment magnitud scale) eartquake of Valdivia 1960 was shallow, 33 km deep.
What causes more damage shallow or deep focus earthquakes?
Shallow focus earthquakes generally cause more damage.
