plate movements are one of the reasons forearthquake what are the three reasons?
Answers
Causes of Earthquakes in General
Induced Earthquakes. Induced quakes are caused by
- human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.Volcanic Earthquakes. Volcanic quakes are associated with active volcanism. ... Collapse Earthquakes.
The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years.
The reasons for plate movements :
- Convection currents
- slab pull
- and ridge push move Earth's huge tectonic plates
- Convection currents in the mantle are much slower than those in boiling water.
Explanation:
Types of earth quakes are:
Tectonic Earthquakes
Earthquakes caused by plate tectonics are called tectonic quakes. They account for most earthquakes worldwide and usually occur at the boundaries of tectonic plates.
Induced Earthquakes
Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
Volcanic Earthquakes
Volcanic quakes are associated with active volcanism. They are generally not as powerful as tectonic quakes and often occur relatively near the surface. Consequently, they are usually only felt in the vicinity of the hypocentre.
Collapse Earthquakes
Collapse quakes can be triggered by such phenomena as cave-ins, mostly in karst areas or close to mining facilities, as a result of subsidence.
