An earthquake is a violent shaking of Earth’s surface. Where are earthquakes common?

Earthquakes are most common in regions located along tectonic plate boundaries, where the Earth's lithospheric plates interact with one another. Here are a few key areas where earthquakes are particularly frequent:

  1. The Pacific Ring of Fire: This is an area encircling the Pacific Ocean, characterized by a high level of tectonic activity. Countries like Japan, Indonesia, the Philippines, and the west coasts of the Americas experience numerous earthquakes due to the movement of the Pacific Plate and surrounding plates.

  2. The Himalayan Region: The collision between the Indian Plate and the Eurasian Plate creates significant seismic activity, leading to earthquakes in countries like Nepal and India.

  3. San Andreas Fault: Located in California, USA, this transform fault marks the boundary between the Pacific Plate and the North American Plate. It is well-known for its frequent earthquakes.

  4. Mid-Atlantic Ridge: This underwater mountain range is a divergent boundary where new ocean floor is created. It experiences frequent seismic activity due to tectonic movement.

  5. East African Rift: This is an area where the African Plate is splitting into two smaller plates, leading to earthquakes in countries like Ethiopia and Kenya.

  6. Alpide Belt: This region, which includes parts of Southern Europe, the Mediterranean, and into the Middle East, experiences earthquakes due to the collision of the African and Eurasian plates.

Overall, regions near active tectonic plate boundaries are more susceptible to earthquakes, while those located in the interior of tectonic plates (like the central U.S.) tend to experience them less frequently, though they are not immune.
