World Earthquake Belts

The earthquake zone occurs at the boundaries of the tectonic plate, and earthquakes occur along these boundaries. These global zones are called earthquake zones.

     In the Pacific Earthquake Zone, which is the most intense earthquake zone in the world, 81% of the major earthquakes in the world occur. 17% of the earthquakes take place in the Alp-Himalaya Earthquake Zone. The biggest earthquakes in the world, namely the Alaska and Chile earthquakes, occurred here. There was a 9.5 magnitude earthquake in Chile in 1960. In 1964, a 9.2 magnitude earthquake occurred in Alaska.

Pacific Earthquake Zone: Also known as the Pacific ring of fire. This earthquake zone surrounds the vast ocean and 75% of active volcanoes are located here. This belt is about 40,000 km long. From Chile to the north, it stretches from the South American coast, Central America, Mexico, the western coast of the USA and south of Alaska to the Aleut Islands, Japan, the Philippines, New Guinea, the South Pacific Islands and New Zealand.

Alpine-Himalayan Earthquake Zone: It is the second biggest earthquake zone after the Pacific Earthquake Zone. Starting from Indonesia, it stretches from the Himalayas and Mediterranean to the Atlantic Ocean. A large part of Turkey is located in the earthquake zone.

The African Plate and the Indian Plate moved to the north, colliding with Europe and Asia. This created the Alp-Himalaya mountain belt.

    Fault Lines in Turkey

Turkey, North Anatolian fault line, the East Anatolian fault line and is located on the third line to the West Anatolian fault line earthquake. There are frequent earthquakes in our country. As mentioned earlier, most of our country is located in the Alpine-Himalayan earthquake zone. The Aegean region is one of the places where earthquakes are most active in the world. Earthquakes are called shallow earthquakes between 0-60 km, medium depth earthquakes between 60-300 km, deep earthquakes above 300 km and above. shallow earthquakes often take place in Turkey.

    Turkey and the Eurasian Plate, and is located between the Arabian Plate and the African Plate. Arabian Plate to compress the Turkey. The African Plate moves 18 mm / year to the north west every year, and as a result, the Anatolian Plate moves to the west every year by 25 mm / year and moves to the west by opening like the fingers of one hand. Therefore, earthquakes occur very frequently in these regions.

East Anatolian Fault:

This fault line is a large fault located to the east of Turkey. This fault line starts from Maras at the north end of the Dead Sea crack and continues in the northeast direction and ends in Karlıova. Here it also meets the North Anatolian Fault line. The East Anatolian fault line consists of many left-sided strike-slip faults that have different characteristics and complement each other between Karlıova and Antakya. Keban Dam, Elazığ, is located on this fault line.

North Anatolian Fault Line:

It extends in the east-west direction between Karlıova in the east and Mudurnu Valley in the west. It is about 1500 km long. It is one of the fastest moving and most active right lateral slip faults in the world. It is not a single fault, it is a fault consisting of many parts.

West Anatolian Fault Line:

It is an earthquake zone extending from east to west, lined from north to south and consisting of many faults.
