Geography
Context: Recently an earthquake of magnitude 7.8 struck Turkiye, one of the most seismically active regions in the Mediterranean and the world.
About the Anatolian Plate:
- Turkiye (the Turkish/Anatolian plate) sits between three major tectonic plates: African, Arabian and Eurasian.
- The Anatolian Plate is a continental tectonic plate comprising most of the Anatolia (Asia Minor) peninsula (and the country of Turkey).
- To the east, the East Anatolian Fault, a left lateral transform fault, forms a boundary with the Arabian Plate.
- To the south and southwest is a convergent boundary with the African Plate.
- The Anatolian plate is divided into three major fault zones: North Anatolian Fault Zone (NAFZ), East Anatolian Fault Zone (EAFZ), South Eastern Anatolian Thrust Zone (SAT)
- Collisions between the Arabian and African plates with Eurasia typically result in earthquakes.
Modified Mercalli Intensity Scale
- It is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake.
