1721 Tabriz Earthquake
The 1721 Tabriz earthquake occurred on April 26, with an epicenter near the city of Tabriz, Iran. It leveled some three-quarters of the city, including many prominent mosques and schools in the city, and resulted in the deaths of tens of thousands of people. The total number of casualties caused by the earthquake is between 8,000 and 250,000; it was most likely approximately 80,000. At the time that it occurred, the earthquake was popularly interpreted as an omen of misfortune, or a demonstration of godly wrath. The destruction that the earthquake caused was a significant factor in the successful Ottoman takeover of Tabriz in 1725, as well as contributing to Tabriz's economic difficulties during that period. It also caused the destruction of some of the city's significant historical monuments. Accounts of the earthquake are often confused with descriptions of the 1727 Tabriz earthquake.

Surface Wave Magnitude
The surface wave magnitude (M_s) scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements of Rayleigh surface waves that travel along the uppermost layers of the Earth. This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with modifications from both Richter and Beno Gutenberg throughout the 1940s and 1950s. It is currently used in People's Republic of China as a national standard (GB 17740-1999) for categorising earthquakes. Recorded magnitudes of earthquakes through the mid 20th century, commonly attributed to Richter, could be either M_s or M_L. Definition The formula to calculate surface wave magnitude is: :M_s = \log_\left(\frac\right)_ + \sigma(\Delta)\,, where A is the maximum particle displacement in surface waves (vector sum of the two horizontal displacements) in μm, T is the corresponding period in s (usually 20 2 seconds), Δ is the epi ...

Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Tabriz
Tabriz ( fa, تبریز ; ) is a city in northwestern Iran, serving as the capital of East Azerbaijan Province. It is the List of largest cities of Iran, sixth-most-populous city in Iran. In the Quri Chay, Quru River valley in Iran's historic Azerbaijan (Iran), Azerbaijan region between long ridges of volcanic cones in the Sahand and Eynali mountains, Tabriz's elevation ranges between above sea level. The valley opens up into a plain that gently slopes down to the eastern shores of Lake Urmia, to the west. With cold winters and temperate summers, Tabriz is considered a summer resort. It was named World Carpet Weaving City by the World Crafts Council in October 2015 and Exemplary Tourist City of 2018 by the Organisation of Islamic Cooperation. With a population of over 1.7 million (2016), Tabriz is the largest economic hub and metropolitan area in northwest Iran.

Epicenter
The epicenter, epicentre () or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...

It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Turkoman tribal leader Osman I. After 1354, the Ottomans crossed into Europe and, with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed the Conqueror.

1727 Tabriz Earthquake
The 1727 Tabriz earthquake occurred on 18 November with an epicenter near Tabriz in northwest Iran. The maximum felt intensity was VIII (''Severe'') on the Mercalli intensity scale, and there were an estimated 77,000 deaths. The only record for this earthquake comes from an account written in 1821 and it is very likely that the information for this earthquake refers instead to the 1721 Tabriz earthquake.

List Of Earthquakes In Iran
Iran is one of the most seismically active countries in the world, being crossed by several major faults that cover at least 90% of the country. As a result, earthquakes in Iran occur often and are destructive. Geology and history The Iranian plateau is subject to most types of tectonic activity, including active folding, faulting and volcanic eruptions. It is well known for its long history of disastrous earthquake activity. Not only have these earthquakes killed thousands, but they have also led to waste of valuable natural resources. Since 1900, at least 126,000 fatalities have resulted from earthquakes in Iran. In addition, the Iranian Plate is bordered by the Indian Plate (to the southeast), the Eurasian Plate (to the north), and the Arabian Plate (to the south and west), which is where the Zagros fold and thrust belt (an ancient subduction zone) lies.

List Of Historical Earthquakes
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the beginning of the 20th century. As the events listed here occurred before routine Seismometer, instrumental recordings, they rely mainly on the analysis of written sources. There is often significant uncertainty in location and magnitude and sometimes date for each earthquake. The number of fatalities is also often highly uncertain, particularly for the older events.
