Flag Of The Russian Soviet Federative Socialist Republic (1918–1925)
The last Soviet Union (USSR)-era flag was adopted by the Russian SFSR in 1954 and used until 1991. The flag of the Russian SFSR was a defacement of the flag of the Soviet Union. The constitution stipulated: Like the flag of the Soviet Union (USSR), the hammer and sickle represented the working class; more specifically, the hammer represented the urban industrial workers and the sickle represented the rural and agricultural peasants. The red star represented the CPSU and Communism. The red in the flag represented the Russian Revolution and revolution in general. The blue stripe symbolized the wide Russian skies and the waters of its seas and rivers. History The first flag of the Russian SFSR, adopted on 14 April 1918, was a flag showing the full name of the recently born Soviet republic before the then imminent Russian spelling reform. Its ratio was unspecified. From June 1918, the flag was red with the gold Cyrillic characters РСФСР (''RSFSR'') in the top-left corner ...

Shan State
Shan State ( my, ရှမ်းပြည်နယ်, ; shn, မိူင်းတႆး, italics=no) also known by the Endonym and exonym, endonyms Shanland, Muang Tai, and Tailong, is a administrative divisions of Myanmar, state of Myanmar. Shan State borders China (Yunnan) to the north, Laos (Louang Namtha Province, Louang Namtha and Bokeo Provinces) to the east, and Thailand (Chiang Rai Province, Chiang Rai, Chiang Mai Province, Chiang Mai and Mae Hong Son Provinces) to the south, and five administrative divisions of Burma (Myanmar) in the west. The largest of the 14 administrative divisions by land area, Shan State covers 155,800 km2, almost a quarter of the total area of Myanmar. The state gets its name from Burmese name for the Tai peoples: "Shan people". The Tai (Shan) constitute the majority among several ethnic groups that inhabit the area. Shanland is largely rural, with only three cities of significant size: Lashio, Kengtung, and the capital, Taunggyi. Taunggyi ...

February 1923 Kamchatka Earthquake
The February 1923 Kamchatka earthquake occurred on 3 February 1923. The epicenter was on the southeastern coast of the Kamchatka Peninsula. The earthquake triggered a tsunami with wave heights up to eight metres, causing damage as far away as Hawaii. The maximum perceived Mercalli intensity was XI (''Extreme''). The tsunami caused two deaths in Kamchatka and one in Hawaii. The earthquake happened 26 years before the U.S. had the capability to issue tsunami warnings, but Thomas Jaggar, the director of the Hawaiian Volcano Observatory, tried to warn the Hilo harbormaster about the possibility of a tsunami. His warning was not taken seriously and one fisherman was killed when the tsunami hit. In April that same year, a smaller 7.2 earthquake struck north of where the February earthquake was. It generated a much larger tsunami with run-ups of up to 30 meters, killing at least 36 people. This earthquake is considered a doublet of the April event because its moment magnitude was reca ...

Foreshock
A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as ''foreshock'', ''mainshock'' or aftershock is only possible after the full sequence of events has happened. Occurrence Foreshock activity has been detected for about 40% of all moderate to large earthquakes, and about 70% for events of M>7.0. They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events. Some great earthquakes (M>8.0) show no foreshock activity at all, such as the M8.6 1950 India–China earthquake. The increase in foreshock activity is difficult to quantify for individual earthquakes but becomes apparent when combining the results of many different events. From such combined observations, the increase before the mai ...

Kamchatka
The Kamchatka Peninsula (russian: полуостров Камчатка, Poluostrov Kamchatka, ) is a peninsula in the Russian Far East, with an area of about . The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and the Karaginsky Island, constitute the Kamchatka Krai of the Russian Federation. The vast majority of the 322,079 inhabitants are ethnic Russians, although about 13,000 are Koryaks (2014). More than half of the population lives in Petropavlovsk-Kamchatsky (179,526 in 2010) and nearby Yelizovo (38,980). The Kamchatka peninsula contains the volcanoes of Kamchatka, a UNESCO World Heritage Site. Geography Politically, the peninsula forms part of Kamchatka Krai. The southern tip is called Cape Lopatka. (Lopatka is Russian for spade.) The circular bay to t ...

Loyalty Islands
The Loyalty Islands Province ( French ''Province des îles Loyauté'') is one of three administrative subdivisions of New Caledonia encompassing the Loyalty Island (french: Îles Loyauté) archipelago in the Pacific, which are located northeast of the New Caledonian mainland of Grande Terre. The provincial government seat is part of the French territory of New Caledonia, at Lifou, which is away. The Loyalty Islands are a ''collectivité territoriale'' of France. The province's 2019 population was approximately 18,353 inhabitants living on almost . The native inhabitants are the Kanak and the Tavu'avua' peoples. History The first Western contact on record is attributed to British Captain William Raven of the whaler ''Britannia'', who was on his way in 1793 from Norfolk Island to Batavia (now called Jakarta). It is very likely, however, that the discovery and name originated with officials on the London ship ''Loyalty'', which was on a Pacific Ocean trading voyage from 1789 to ...

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 ...
