There are no earthquakes in the countries mentioned because these countries are located far from tectonic plate boundaries or fault lines, typically in the middle of tectonic plates. Earthquakes most commonly occur along the edges of tectonic plates where the plates interact, such as through subduction, collision, or sliding past each other. In contrast, the interiors of tectonic plates tend to be more geologically stable and thus experience fewer or no significant earthquakes. This stable location away from active fault lines means these countries do not have the geological conditions that usually cause earthquakes.
To summarize:
- Earthquakes mainly occur at tectonic plate boundaries.
- Countries located centrally within plates are generally free from earthquakes.
- These countries have stable ground that is not subject to the movements and stresses causing earthquakes.
- Examples of such countries include Qatar, Saudi Arabia, Malta, Andorra, and parts of central Africa and Russia.
Therefore, the absence of earthquakes in these countries is primarily due to their geographical location on stable parts of the Earth's crust, away from zones where tectonic activity occurs.
