Deep focus earthquakes occur at depths greater than 300 kilometers (about 186 miles) within the Earth's mantle, primarily due to the subduction of tectonic plates. As an oceanic plate descends into the mantle, it can become trapped and subjected to extreme pressure and temperature, leading to the breakdown of minerals and the release of energy. This process can create seismic activity even at significant depths, resulting in deep focus earthquakes. Unlike shallow earthquakes, the mechanisms involved are less well understood but may involve complex interactions between mineral phases and fluids in the mantle.

What are the effects of deep focus earthquakes?

Very little, as the earthquake occurs deep underground, hence the deep focus.


What causes more damage shallow or deep focus earthquakes?

Shallow-focus earthquakes cause more damage than deep-focus earthquakes. This is because shallow-focus earthquakes originate closer to the Earth's surface, which allows the energy to be more concentrated and lead to stronger shaking and more destruction of structures. Deep-focus earthquakes, occurring deeper underground, tend to have their energy dissipate before reaching the surface.


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 focus intermediate focus and deep focus occur?

Shallow focus, intermediate focus, and deep focus refer to different depths of field in photography and cinematography. Shallow focus occurs when only a small part of the scene is in sharp focus, typically used to isolate a subject from the background. Intermediate focus provides a clearer view of both the subject and some background elements, while deep focus keeps the entire scene, from foreground to background, in sharp focus. Each technique serves to create different visual effects and narratives.
