Lori Province
Lori ( hy, Լոռի, ), is a province ('' marz'') of Armenia. It is located in the north of the country, bordering Georgia. Vanadzor is the capital and largest city of the province. Other important towns include Stepanavan, Alaverdi, and Spitak. It is home to the UNESCO World Heritage Sites of Haghpat and Sanahin monasteries and the well-preserved Akhtala monastery, where Armenians, Georgians, and Greeks make an annual pilgrimage on September 20–21. The province was heavily damaged during the 1988 Armenian earthquake. The province is served by the Stepanavan Airport. Etymology The name Lori (Լոռի) is of Armenian origin (from Armenian "quail"), first appeared in the 11th century when King David I Anhoghin founded the fortified city of Lori. The fortress-city became the capital of the Kingdom of Tashir-Dzoraget in 1065. The name Lori later spread through the region and replaced the original name of Tashir. Geography Situated at the north of modern-day Armenia, Lori c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tmogvi
Tmogvi or Tmkaberd ( ka, თმოგვი ; hy, Թմկաբերդ) is a ruined fortress and medieval town in the southern Georgian region of Samtskhe-Javakheti, on the left bank of the Kura River, a few kilometers downstream of the cave city of Vardzia. History The name "Tmogvi" is derived from Georgian word ''mogvi'' (მოგვი), meaning "pagan priest" or "magus". The fortress is first mentioned in sources from the 9th century. It was built as a defensive work controlling the ancient trade route between the Javakheti plateau and the gorge of Kura, over a gorge formed by the Kura River. It was a crucial military stronghold in the region of Javakheti. The feudal lords of the region were at that time the Bagratids, the Georgian branch. The Georgian chronicles report numerous attempts to take the castle over, but they were rarely successful. Tmogvi gained importance after the neighboring town and fortress of Tsunda was ruined around 900 AD. In 914 Yusuf ibn Abi'l-Saj app ...

Earthquakes In Georgia (country)
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes ca ...

Geology Of Georgia (country)
The geology of Georgia is the study of rocks, minerals, water, landforms and geologic history in Georgia. The country is dominated by the Caucasus Mountains at the junction of the Eurasian Plate and the Afro-Arabian Plate, and rock units from the Mesozoic and Cenozoic are particularly prevalent. For much of its geologic history, until the uplift of the Caucasus, Georgia was submerged by marine transgression events. Geologic research for 150 years by Georgian and Russian geologists has shed significant light on the region and since the 1970s has been augmented with the understanding of plate tectonics. Stratigraphy & Tectonics The Georgian Block in the Dzirula Massif is part of the Main Range zone of the Greater Caucasus and the Lesser Caucasus fold system. The south slope of the Greater Caucasus has exposed Paleozoic rocks in the Svaneti Zone, including black shale, phthanite chert, sandstones, turbidites, small amounts of marble and andesite or dacite volcanic rocks. These rocks, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Earthquakes/notability Guidelines
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

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 ...

Body Wave Magnitude
Body-waves consist of P-waves that are the first to arrive (see seismogram), or S-waves, or reflections of either. Body-waves travel through rock directly. mB scale The original "body-wave magnitude" – mB or mB (uppercase "B") – was developed by and to overcome the distance and magnitude limitations of the scale inherent in the use of surface waves. is based on the P- and S-waves, measured over a longer period, and does not saturate until around M 8. However, it is not sensitive to events smaller than about M 5.5. Use of as originally defined has been largely abandoned, now replaced by the standardized scale. mb scale The mb or mb scale (lowercase "m" and "b") is similar to , but uses only P-waves measured in the first few seconds on a specific model of short-period seismograph. It was introduced in the 1960s with the establishment of the ''World-Wide Standardized Seismograph Network'' (WWSSN); the short period improves detection of smaller events, and better discri ...

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] |
