1944 Bolu–Gerede Earthquake
The 1944 Bolu–Gerede earthquake occurred at 05:22 local time on 1 February. The earthquake had an estimated magnitude of 7.74 and a maximum felt intensity of IX–X (''Violent''–''Extreme'') on the Mercalli intensity scale. It ruptured part of the North Anatolian Fault, forming part of a progressive sequence of events that generally migrated westwards along the fault zone, starting with the 1939 Erzincan earthquake. Tectonic setting Both Bolu and Gerede lie close to the active North Anatolian Fault (NAF), a major right-lateral strike-slip fault zone that forms the transform boundary between the Anatolian plate and the Eurasian plate to the north. The Anatolian plate is being driven westwards by the northward movement of the Arabian plate. It runs from the Karlıova triple junction in the east to the northern Aegean Sea in the west. The NAF is formed of many individual strands and segments, most of which are associated with historical earthquakes. Earthquakes along the ...

Turkey
Turkey, officially the Republic of Türkiye, is a country mainly located in Anatolia in West Asia, with a relatively small part called East Thrace in Southeast Europe. It borders the Black Sea to the north; Georgia (country), Georgia, Armenia, Azerbaijan, and Iran to the east; Iraq, Syria, and the Mediterranean Sea to the south; and the Aegean Sea, Greece, and Bulgaria to the west. Turkey is home to over 85 million people; most are ethnic Turkish people, Turks, while ethnic Kurds in Turkey, Kurds are the Minorities in Turkey, largest ethnic minority. Officially Secularism in Turkey, a secular state, Turkey has Islam in Turkey, a Muslim-majority population. Ankara is Turkey's capital and second-largest city. Istanbul is its largest city and economic center. Other major cities include İzmir, Bursa, and Antalya. First inhabited by modern humans during the Late Paleolithic, present-day Turkey was home to List of ancient peoples of Anatolia, various ancient peoples. The Hattians ...

Coulomb Stress Transfer
Coulomb stress transfer is a Seismology, seismic-related geology, geological process of Stress (mechanics), stress changes to surrounding material caused by local discrete deformation events. Using mapped displacements of the Earth's surface during earthquakes, the computed Coulomb stress changes suggest that the stress relieved during an earthquake not only dissipates but can also move up and down Fault (geology), fault segments, concentrating and promoting subsequent tremors. Importantly, Coulomb stress changes have been applied to earthquake-forecasting models that have been used to assess potential Seismic hazard, hazards related to earthquake activity. Coulomb stress change The Mohr–Coulomb theory, Coulomb failure criterion requires that the Coulomb stress exceeds a value σf defined by the shear stress τB, normal stress σB, pore pressure p, and coefficient of friction μ of a failure plane, such that It is also often assumed that changes in pore fluid pressure induced b ...

February 1944 In Asia
February is the second month of the year in the Julian calendar, Julian and Gregorian calendars. The month has 28 days in common years and 29 in leap years, with the February 29, 29th day being called the ''leap day''. February is the third and last month of meteorological winter in the Northern Hemisphere. In the Southern Hemisphere, February is the third and last month of meteorological summer, being the seasonal equivalent of August in the Northern Hemisphere. Pronunciation "February" can be pronounced in several different ways. The beginning of the word is commonly pronounced either as or ; many people drop the first "r", replacing it with , as if it were spelled "Febuary". This comes about by analogy with "January" (), as well as by a dissimilation effect whereby having two "r"s close to each other causes one to change. The ending of the word is pronounced in the US and in the UK. History The Roman month was named after the Latin term , which means "purific ...
