1969 Banja Luka Earthquake
A series of earthquakes struck Banja Luka on October 26 and 27, 1969. The earthquakes began with an unusually strong tremor on the night of October 26 at 02:55. Foreshocks commenced several hours later and small tremors continued until 08:53. The mainshock occurred at 16:36. The hypocenter was below the city with a Moment magnitude scale, moment magnitude of 6.1 maximum Mercalli intensity scale, Mercalli intensity of VIII (''Severe''). The earthquake was followed by a 6.1 magnitude a day later. It was categorized as a doublet earthquake. Damage Material damage was widespread; 86,000 apartments were completely destroyed. Great damage was inflicted on school (266), cultural (146), health (133), social and public administration facilities (152). The economy suffered significant losses. In the following years, all companies worked with significantly reduced capacities, and some completely stopped production. The buses were driven by primary and secondary school students from Banja L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socialist Republic Of Bosnia And Herzegovina
The Socialist Republic of Bosnia and Herzegovina ( sh-Latn-Cyrl, separator=" / ", Socijalistička Republika Bosna i Hercegovina, Социјалистичка Pепублика Босна и Херцеговина), commonly referred to as Socialist Bosnia or simply Bosnia, was one of the six constituent federal states forming the Socialist Federal Republic of Yugoslavia. It was a predecessor of the modern-day Bosnia and Herzegovina, existing between 1945 and 1992, under a number of different formal names, including Democratic Bosnia and Herzegovina (1943–1946) and People's Republic of Bosnia and Herzegovina (1946–1963). Within Yugoslavia, Bosnia and Herzegovina was a unique federal state with no dominant ethnic group, as was the case in other constituent states, all of which were also nation states of Yugoslavia's South Slavic ethnic groups. It was administered under strict terms of sanctioned consociationalism, known locally as "ethnic key" ( sh-Latn-Cyrl, separator=" / ", ...

Banja Luka
Banja Luka ( sr-Cyrl, Бања Лука, ) or Banjaluka ( sr-Cyrl, Бањалука, ) is the second largest city in Bosnia and Herzegovina and the largest city of Republika Srpska. Banja Luka is also the ''de facto'' capital of this entity. It is the traditional centre of the densely-forested Bosanska Krajina region of northwestern Bosnia. , the city proper has a population of 138,963, while its administrative area comprises a total of 185,042 inhabitants. The city is home to the University of Banja Luka and University Clinical Center of the Republika Srpska, as well as numerous entity and state institutions for Republika Srpska and Bosnia and Herzegovina respectively. The city lies on the Vrbas river and is well known in the countries of the former Yugoslavia for being full of tree-lined avenues, boulevards, gardens, and parks. Banja Luka was designated European city of sport in 2018. Name The name ''Banja Luka'' was first mentioned in a document dated to 6 February 1494 b ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercalli Intensity Scale
The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "" magnitude usually reported for an earthquake). While shaking is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. Deeper earthquakes also have less interaction with the surface, and their energy is spread out across a larger volume. Shaking intensity is localized, generally diminishing with distance from the earthquake's epicenter, but can be amplified in sedimentary basins and certain kinds of unconsolidated soils. Intensity scales empirically categorize the intensity of shaking based on the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doublet Earthquake
__NOTOC__ In seismology, doublet earthquakes – and more generally, multiplet earthquakes – were originally identified as multiple earthquakes with nearly identical waveforms originating from the same location. They are now characterized as single earthquakes having two (or more) main shocks of similar magnitude, sometimes occurring within tens of seconds, but sometimes separated by years. The similarity of magnitude – often within 0.4 magnitude – distinguishes multiplet events from aftershocks, which start at about 1.2 magnitude less than the parent shock ( Båth's law) and decrease in magnitude and frequency according to known laws. Doublet/multiplet events also have nearly identical seismic waveforms, as they come from the same rupture zone and stress field, whereas aftershocks, being peripheral to the main rupture, typically reflect more diverse circumstances of origin. Multiplet events overlap in their focal fields (rupture zones), which can be up 100 kilometers across ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SFRY
The Socialist Federal Republic of Yugoslavia, commonly referred to as SFR Yugoslavia or simply as Yugoslavia, was a country in Central and Southeast Europe. It emerged in 1945, following World War II, and lasted until 1992, with the breakup of Yugoslavia occurring as a consequence of the Yugoslav Wars. Spanning an area of in the Balkans, Yugoslavia was bordered by the Adriatic Sea and Italy to the west, by Austria and Hungary to the north, by Bulgaria and Romania to the east, and by Albania and Greece to the south. It was a one-party socialist state and federation governed by the League of Communists of Yugoslavia, and had six constituent republics: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Within Serbia was the Yugoslav capital city of Belgrade as well as two autonomous Yugoslav provinces: Kosovo and Vojvodina. The SFR Yugoslavia traces its origins to 26 November 1942, when the Anti-Fascist Council for the National Liberation of Yugoslavia was ...

List Of Earthquakes In 1969
This is a list of earthquakes in 1969. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. Activity generally was slightly below average with 14 events reaching magnitude 7 or greater. In August, the largest event of the year struck the Kuril Islands, Russia measuring 8.2. Other large events struck offshore Portugal and Indonesia. The Americas had no events above magnitude 7 which is an uncommon occurrence. Of the 4,000 deaths from earthquakes two events dominated. Southeastern China had an earthquake of magnitude 5.7 in July which contributed 4,024 of the total. Indonesia had th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2020 Petrinja Earthquake
At approximately 12:20 PM CET (11:20 UTC) on 29 December 2020, an earthquake of magnitude 6.4 (6.2 ) hit central Croatia, with an epicenter located roughly west-southwest of Petrinja. The maximum felt intensity was estimated at VIII (''Heavily damaging'') to IX (''Destructive'') on the European macroseismic scale. Before this event there were three foreshocks, the strongest of which had a magnitude of 5.2 on the day before. The earthquake was followed by numerous aftershocks, the strongest of which had a magnitude of 4.9 . The adversely affected areas were mostly in the Sisak-Moslavina County and other nearby Croatian counties, as well as some of the nearby areas of Bosnia and Slovenia. Seven people were confirmed dead, while 26 others were injured, with six having serious injuries. Initial reports show many buildings destroyed in Petrinja. The mayor of Petrinja, Darinko Dumbović, said that half of the town has been destroyed. The first multidisciplinary scientific paper on ...
