What are the 5 causes of earthquake?

As a geologist with expertise in seismology, I can explain the primary causes of earthquakes. While the list you provided includes some factors that can influence seismic activity, there are five main causes that are widely recognized in the field of seismology: 1. Tectonic Plate Movement: The majority of earthquakes are caused by the movement of the Earth's tectonic plates. When these massive plates collide, pull apart, or slide past one another, the stress accumulated along their boundaries can cause the Earth's crust to rupture, resulting in an earthquake. 2. Volcanic Activity: Earthquakes can also be triggered by volcanic activity. As magma moves beneath the Earth's surface, it can cause the crust to shift, leading to seismic events. 3. Subduction: This is a specific type of tectonic plate movement where one plate is forced under another. The friction and pressure at the subduction zone can build up and release energy in the form of earthquakes. 4. Fault Slip: Earthquakes occur when there is a sudden slip along a fault line. Faults are fractures in the Earth's crust where the movement of tectonic plates is concentrated. 5. Human Activities: While less common, human activities such as mining, reservoir-induced seismicity (building dams and large reservoirs), and fluid injection (as in the case of fracking or wastewater disposal) can also cause small to moderate-sized earthquakes.
