| Induced Earthquakes Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects | 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 | Earthquakes are caused by a sudden release of stress along faults in the earth's crust |
Volcanic Earthquakes Volcanic quakes are associated with active volcanism.
| 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 | The continuous motion of tectonic plates causes a steady build-up of pressure in the rock strata on both sides of a fault until the stress is sufficiently great that it is released in a sudden, jerky movement |
|---|---|
| The resulting waves of seismic energy propagate through the ground and over its surface, causing the shaking we perceive as earthquakes | They are generally not as powerful as tectonic quakes and often occur relatively near the surface |
| These plates move towards each other a convergent boundary , apart a divergent boundary or past each other a transform boundary | Consequently, they are usually only felt in the vicinity of the hypocentre |
