Aergus (the volcano Erciyes). He won a state scholarship to study natural sciences abroad, as part of Mustafa Kemal Atatürk's plans of modernizing the newly formed Republic of Turkey. He started his undergraduate studies in Natural Sciences at Berlin University in 1934, and subsequently completed his doctorate at Bonn University in 1938 under the supervision of Hans Cloos, thus becoming the first native of Turkey with a doctorate degree in geology in the Republic of Turkey. Ketin returned to Turkey in 1938, and started his career as assistant professor at the Geological Institute of Istanbul Technical University. Scientific career Through a faithful coincidence, the long-dormant North Anatolian fault awoke to activity, first gently with the Tercan quake of 21 November 1939, but then violently ...

1939 Erzincan Earthquake
The 1939 Erzincan earthquake struck eastern Turkey at with a moment magnitude of 7.8 and a maximum Mercalli intensity of XII (''Extreme''). It was the second most powerful earthquake recorded in Turkey, after the 1668 North Anatolia earthquake. This was one of the largest in a sequence of violent shocks to affect Turkey along the North Anatolian Fault between 1939 and 1999. Surface rupturing, with a horizontal displacement of up to 3.7 meters, occurred in a 360 km long segment of the North Anatolian Fault Zone. The earthquake was the most severe natural loss of life in Turkey in the 20th century, with 32,968 dead, and some 100,000 injured. Preface The North Anatolian Fault in Asia Minor is a major transform fault boundary where the Eurasian Plate slides past the smaller Anatolian Microplate. Running for over 1,600 km, the fault stretches from Eastern Turkey to the Sea of Marmara. The North Anatolian fault has been, and remains very active. Erzincan has been destroyed ...

Paleo-Tethys Ocean
The Paleo-Tethys or Palaeo-Tethys Ocean was an ocean located along the northern margin of the paleocontinent Gondwana that started to open during the Middle Cambrian, grew throughout the Paleozoic, and finally closed during the Late Triassic; existing for about 400 million years. Paleo-Tethys was a precursor to the Tethys Ocean (also called the Neo-Tethys) which was located between Gondwana and the Hunic terranes (continental fragments that broke-off Gondwana and moved north). It opened as the Proto-Tethys Ocean subducted under these terranes and closed as the Cimmerian terranes (that also broke-off Gondwana and moved north) gave way to the Tethys Ocean. Confusingly, the Neo-Tethys is sometimes defined as the ocean south of a hypothesised mid-ocean ridge separating Greater Indian from Asia, in which case the ocean between Cimmeria and this hypothesised ridge is called the Meso-Tethys, i.e. the "Middle-Tethys". The so-called Hunic terranes are divided into the ''European Hunic' ...

Anatolia
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with Asian ...

Kapıdağ Peninsula
Kapıdağ Peninsula ( tr, Kapıdağ Yarımadası) ( gr, Χερσόνησος της Κυζίκου ) is a tombolo in northwestern Anatolia extending into the Sea of Marmara in Balıkesir Province, Turkey. The peninsula forms the Gulf of Bandırma on its east and the Gulf of Erdek on its west.

It was also known as the Peninsula of Cyzicus after its chief town. Cyzicus was abandoned following a series of severe earthquakes, but served from 1303 to 1304 as the base of the Catalan Company of the East and was the site of the Battle of the Cyzicus in October 1303. After its conquest by the Ottoman Empire, it was part of the kaza of Erdek in the province of Bursa.

Inaugural Dissertation
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism ''licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals de ...

Professor Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

Orogeny
Orogeny is a mountain building process. An orogeny is an event that takes place at a convergent plate margin when plate motion compresses the margin. An ''orogenic belt'' or ''orogen'' develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis. These include both structural deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen carries less dense material upwards while leaving more dense material behind, resulting in compositional differentiation of Earth's lithosphere ( crust and uppermost mantle). A synorogenic process or event is one that occurs during an orogeny. The word "orogeny" () comes from Ancient Greek (, , + , , ). Although it was used before him, the term was employed by the American geologist G. K. Gilbert in 1890 to describe the process of mountain-building as distinguished f ...
