Earthquakes happen all the time
|
|
|
Earthquakes are happening almost everyday all over the world. Most of the time earthquakes are not strong enough to be felt by people, but a seismograph records the shaking caused by an earthquake. These are located all over the world at different points. ... Around the world there are many faults, depending where these faults are plays a major factor in determining where an earthquake will happen. It is these faults that are the reason for earthquakes. The type of fault will also determine how often an earthquake will happen. ...
It is these normal faults that are the cause and therefore the origin of earthquakes at divergent boundaries. ... The normal faults happen because the crust is being extended. ... They move a large distance in a relatively short space of time; this is the cause of the earthquakes at divergent boundaries.
Divergent boundaries mostly occur on the sea floor and therefore the earthquakes that happen at these boundaries are distributed along the boundary. This means that the distributions of earthquakes at divergent boundaries are at shallow depths, where the crust is been pulled apart. The earthquakes happen at shallow depths because the normal faulting occurs near the sea floor, as a result of the tension. The normal faults are the cause of the earthquakes at these divergent boundaries.
The seafloor sees the most intense tectonic activity in the world, meaning that at the sites of mid-ocean ridges the frequency of earthquakes is very high. ... The frequency of earthquakes at a mid-ocean ridge will depend on how much tension is happening at that point. The more tension means the more seafloor spreading, resulting in a higher frequency of earthquakes at a particular mid-ocean ridge. ... Within the basins of these oceans earthquakes can happen without been caused at Mid-ocean ridges, or a Seduction Zones. ... This can happen to the oceanic crust in the ocean basins, but will only cause an earthquake with a hot spot.
