What movement of plates causes earthquake activity?
The earths plates will move around and now and again hit each other this will cause the earthquake
the plate tectonics will collide and slide past each other causing the earth to shake known as the earthquake
The Italian earth quake was most probably caused by the movement of the Eurasian and African tectonic plates. Convection currents in the earths mantle cause these plates to move which in turn causes stresses at the plate boundaries. When these stresses are released the movement is very sudden. This is the movement said to be an earthquake.
Before an earthquake begins there is movement in the faults and or techtonic plates underground which causes an earthquake. Earthquakes can be caused due to two plates converging (two plates coming together) and they can also be caused due to transform (two plates sliding past eachother in oposite directions). Earthquakes can easily just be caused due to movement in the earth such as faults, like I previously said. Hope this helped :)
A seismic activity is an earthquake... An earthquake is when the tectonic plates (under ground) clash together, which causes an earthquake. Earthquakes can be very small or huge depending on where the country is. They can kill thousands of people, knock down buildings and create huge cracks in the ground. They are measured on a Richter scale. :)
The plates that construct the Earth either slip past each other, or two move towards each other whilst creating a gap between others, this movement causes a vibration in which is the Earthquake. Depending on which plates move, depends on the type of Earthquake and thus, how much damage is caused. Hope it helps :)
An earthquake is when two of the earths plates rub together causing friction which makes the ground move and with the movement of the plates causes the area in which the earthquake is in to shake.An after shock is when the earquake has passed but the earth is still moving so little by little it begins to decrease slowly until there is nothing left of the natural disaster.
