Difference Between Earth Tremors and Earthquakes
- Earth Tremors: These are minor shakes or vibrations of the ground that are usually imperceptible to people. They are often too small to be felt but can be detected by seismographs. Earth tremors can occur as a result of small shifts in the Earth’s crust or as precursors to larger seismic events.
- Earthquakes: These are more significant and intense than earth tremors. An earthquake occurs when there is a sudden release of energy in the Earth’s crust, causing the ground to shake. Earthquakes can range from minor quakes that are barely felt to major ones that can cause substantial damage.
Causes of Earth Tremors and Earthquakes
- Earth Tremors: These can be caused by minor movements in the Earth’s crust, such as the adjustment of tectonic plates, volcanic activity, or even human activities like mining and reservoir-induced seismicity. They are generally less powerful and less damaging.
- Earthquakes: These are primarily caused by the movement of tectonic plates, which are massive sections of the Earth’s crust that float on the semi-fluid mantle beneath. When these plates grind past each other, they can become stuck due to friction. When the stress exceeds the friction, it causes a sudden release of energy, resulting in an earthquake. Other causes of earthquakes include volcanic activity, landslides, and human activities like hydraulic fracturing (fracking).
Understanding the distinction between earth tremors and earthquakes, along with their causes, helps in assessing seismic risks and preparing for potential impacts.
