October 2016 Central Italy Earthquakes
A series of major earthquakes struck Central Italy between the Marche and Umbria regions in October 2016. The third quake on 30 October was the largest in Italy in 36 years, since the 1980 Irpinia earthquake. Earthquakes A magnitude 5.5 earthquake struck east southeast of Sellano on 26 October at 19:11 local time (17:11 UTC) at a depth of . The earthquake was also felt in the city of Rome. In the region of Marche some houses collapsed, Italian media reported. There were also power failures and the telephone lines were interrupted. A magnitude 6.1 intraplate earthquake struck west of Visso on 26 October at 21:18 local time (19:18 UTC). The earthquake, which occurred two months after a magnitude 6.2 earthquake in August, struck about to the northwest of the August earthquake's epicenter. The civil protection, however, estimated the consequences less dramatically than feared. According to official data, a man died because he had suffered a hear ...

Central Italy
Central Italy ( it, Italia centrale or just ) is one of the five official statistical regions of Italy used by the National Institute of Statistics (ISTAT), a first-level NUTS region, and a European Parliament constituency. Regions Central Italy encompasses four of the country's 20 regions: * Lazio * Marches (''Marche'') * Tuscany (''Toscana'') * Umbria The southernmost and easternmost parts of Lazio (Sora, Cassino, Gaeta, Cittaducale, Formia, and Amatrice districts) are often included in Southern Italy (the so-called ''Mezzogiorno'') for cultural and historical reasons, since they were once part of the Kingdom of the Two Sicilies and southern Italian dialects are spoken. As a geographical region, however, central Italy may also include the regions of Abruzzo and Molise, which are otherwise considered part of Southern Italy for socio-cultural, linguistic and historical reasons. Politics Marches, Tuscany and Umbria – together with Emilia-Romagna – are considered to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of Solar time#Mean solar time, mean solar time (such as Universal Time, UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 ...

Apennine Mountains
The Apennines or Apennine Mountains (; grc-gre, links=no, Ἀπέννινα ὄρη or Ἀπέννινον ὄρος; la, Appenninus or – a singular with plural meaning;''Apenninus'' (Greek or ) has the form of an adjective, which would be segmented ''Apenn-inus'', often used with nouns such as ("mountain") or Greek (), but ''Apenninus'' is just as often used alone as a noun. The ancient Greeks and Romans typically but not always used "mountain" in the singular to mean one or a range; thus, "the Apennine mountain" refers to the entire chain and is translated "the Apennine mountains". The ending can vary also by gender depending on the noun modified. The Italian singular refers to one of the constituent chains rather than to a single mountain, and the Italian plural refers to multiple chains rather than to multiple mountains. it, Appennini ) are a mountain range consisting of parallel smaller chains extending along the length of peninsular Italy.

1997 Umbria And Marche Earthquake
The 1997 Umbria and Marche earthquake occurred in the regions of Umbria and Marche, central Italy on the morning of September 26. It was preceded by a foreshock almost as strong as the main quake. The foreshock occurred at 02:33 CEST (00:33 UTC), rated , and the second – the main shock – occurred at 11:40 CEST (09:40 UTC), rated . Their epicentre was in Annifo. The mainshock was assigned X (''Extreme'') and foreshock VIII (''Severe'') on the Mercalli intensity scale. There were several thousands of foreshocks and aftershocks from May 1997 to April 1998, more than thirty of which had a magnitude more than 3.5. Eleven people are known to have died following the shocks. List of foreshocks and aftershocks Only shocks (both foreshocks and aftershocks) with magnitude 5.0 or higher are listed.

Seismic Gap
A seismic gap is a segment of an active fault known to produce significant earthquakes that has not slipped in an unusually long time, compared with other segments along the same structure. There is a hypothesis or theory that states that over long periods of time, the displacement on any segment must be equal to that experienced by all the other parts of the fault. Any large and longstanding gap is, therefore, considered to be the fault segment most likely to suffer future earthquakes. The applicability of this approach has been criticised by some seismologists although earthquakes sometimes have occurred in previously-identified seismic gaps. Examples Loma Prieta Seismic Gap, California Prior to the 1989 Loma Prieta earthquake( = 6.9), that segment of the San Andreas fault system recorded much less seismic activity than other parts of the fault. The main shock and aftershocks of the 1989 event occurred within the previous seismic gap. Central Kuril gap, Russia Immediately foll ...

Rieti
Rieti (; lat, Reate, Sabino: ) is a town and ''comune'' in Lazio, central Italy, with a population of 47,700. It is the administrative seat of the province of Rieti and see of the diocese of Rieti, as well as the modern capital of the Sabina region. The town centre stands on a small hilltop, commanding from the southern edge the wide Rieti valley, at the bottom of the Sabine hills and of monti Reatini, including mount Terminillo. The plain was once a large lake, drained by the ancient Romans, and is now the fertile basin of the Velino River. Only the small Ripasottile and Lungo lakes remain of the larger original. History Prehistory According to the legend, Reate was founded by Rea, a divinity (that would be the origin of the town name). It was founded at the beginning of the Iron Age (9th–8th century BC). Probably in earlier times the lands around Rieti were inhabited by Umbri, then by Aborigines and later on by Sabines, who reached the lands sited in the nearb ...

Macerata
Macerata () is a city and '' comune'' in central Italy, the county seat of the province of Macerata in the Marche region. It has a population of about 41,564. History The historical city centre is on a hill between the Chienti and Potenza rivers. It first consisted of the Picenes city named Ricina (''Helvia Recina''), then, after its romanization, Recina and Helvia Recina. After the destruction of Helvia Recina by the barbarians, the inhabitants took shelter in the hills and eventually began to rebuild the city, first on the top of the hills, before descending again later and expanding. The newly rebuilt town was Macerata. It became a municipality (or comune in Italian) in August 1138. 20th century The ''comune'' of Urbisaglia was the location of an internment camp for Jews and refugees, and a prisoner-of-war camp (PG53, at Sforzacosta) during World War II. 21st century According to Jason Horowitz of '' The New York Times'', Macerata was initially welcoming to migrants c ...

Longitude
Longitude (, ) is a geographic coordinate that specifies the east– west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
