Английская Википедия:1902 Shamakhi earthquake
The 1902 Shamakhi earthquake occurred on 13 February with a surface-wave magnitude of 6.9 and a maximum felt Modified Mercalli intensity of IX (Violent). Up to 2,000 people died and thousands more were injured in the Shemakha uezd within the Baku Governorate of the Russian Empire (present-day Republic of Azerbaijan). About 7,439 buildings were damaged or destroyed in the city and surrounding villages.[1] Shamakhi had been devastated by earlier earthquakes in 1806, 1859 and 1872. It is one of the most destructive earthquakes in Azerbaijan.[2]
Geology
Azerbaijan is situated in a region of subduction involving the Arabian and Eurasian plates which has been ongoing for the past 5 million years. As a result, forming the Greater Caucasus Range. The Main Caucasus Thrust Fault, a north-dipping fault, accommodates most of the plate interaction. Subduction was later accommodated 1.5 million years ago by the Kura fold and thrust belt. The Kura fold and thrust belt spans Шаблон:Cvt from Tbilisi in Georgia to Shamakhi, consisting of a series of thrust faults.[3]
Earthquake
Isoseismal mapping of affected buildings indicate an epicenter location close to Shamakhi and the rupture was consistent with that occurring on the Kura Thrust Fault. Paleoseismic studies involving trenching in Agsu District revealed surface ruptures associated with two earthquakes. The older of the two may correspond to a large earthquake in 1668 while the younger could reflect the 1902 event which displayed Шаблон:Cvt of offset. By estimating a rupture area of Шаблон:Cvt, consistent with the area of major damage, and considering the Шаблон:Cvt of average slip, the moment magnitude (Шаблон:M) is 7.4.[3]
Impact
The earthquake struck at noon, and Shamakhi was totally destroyed. In addition to the city in ruins, the earthquake also devastated 125 nearby settlements. The destruction of 4,000 homes left 20,000 people homeless. Eight historical mosques, 42 churches, more than 10 madrasas, as well as many commercial buildings and shops were destroyed. In the villages outside the city, over 3,000 houses, many mosques and farmhouses were razed.[4] Damage was made worse by fires started from people cooking; it destroyed many structures that were still standing.[5] The destruction of Shamakhi was attributed to wet soil conditions and building materials which consisted of stones and clay mortar. Damage was light in areas where Christians lived because most homes in these areas were constructed from wood.[6]
