2002 Molise Earthquake
Two earthquakes hit the Italian regions of Molise and Apulia on 31 October at 10:32:58 ( UTC) and 1 November at 15:09:00 (UTC). The shocks had magnitudes of 5.9 and 5.8 respectively. Most of the victims were killed and injured when a school collapsed in the town of San Giuliano di Puglia: 26 of the 51 schoolchildren died, together with one of their teachers. In particular, none of the nine children in the school's 4th Year (mostly born in 1996) survived. Tectonic setting Molise and Apulia lie above a series of thrust sheets that were emplaced northeastwards on top of the foreland of the Adriatic Plate due to continental collision during the Neogene. In the southern part of the Apennines, the thrusting is no longer active, but it continues in northern Italy along the southern margin of the Po Plain. The foreland to the east is characterised by zones of active west–east trending dextral (right-lateral) strike-slip faulting. The best described of these zones is the Mattinata F ...

Central European Time
Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time (MET, German: MEZ) and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Madrid Time, Paris Time, Rome Time, Warsaw Time or even Romance Standard Time (RST). The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones. As of 2011, all member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer. In Africa, UTC+01:00 is called West Africa Time (WAT), where it is used by several countries, year round. Algeria, Morocco, and Tunisia also refer to it as ''Central E ...

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along the Croatian part of its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes are known to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marche
Marche ( , ) is one of the twenty regions of Italy. In English, the region is sometimes referred to as The Marches ( ). The region is located in the central area of the country, bordered by Emilia-Romagna and the republic of San Marino to the north, Tuscany to the west, Umbria to the southwest, Abruzzo and Lazio to the south and the Adriatic Sea to the east. Except for river valleys and the often very narrow coastal strip, the land is hilly. A railway from Bologna to Brindisi, built in the 19th century, runs along the coast of the entire territory. Inland, the mountainous nature of the region, even today, allows relatively little travel north and south, except by twisting roads over the passes. Urbino, one of the major cities of the region, was the birthplace of Raphael, as well as a major centre of Renaissance history. Toponymy The name of the region derives from the plural of the medieval word ''marca'', meaning "march" or "mark" in the sense of border zone, originally ...

Province Of Chieti
The province of Chieti ( it, provincia di Chieti; Abruzzese: ') is a province in the Abruzzo region of Italy. Its provincial capital is the city Chieti, which has a population of 50,770 inhabitants. The province has a total population of 387,649 inhabitants and spans an area of . It is divided into 104 '' comuni'' (''comune'') and the provincial president is Mario Pupillo. Chieti's cathedral was first constructed during the 9th century but was reconstructed during the 13th century. The province contains the National Archaeology Museum of Abruzzo, in Italian the ''Museo Archeologico Nazionale d'Abruzzo'', which contains items from the area prior to Roman rule. History It was first settled by the Osci people near the Pescara River. In around 1000 BCE it was conquered by Marsi and Marrucini people. The city was also lived in by the Greeks, who named it Teate. It was conquered by the Romans in 305 BCE but after the fall of Rome in 476 CE, Theoderic the Great gained ownership of ...

Capitanata
The Province of Foggia ( it, Provincia di Foggia ; Foggiano: ) is a province in the Apulia (Puglia) region of southern Italy. This province is also known as Daunia, after the Daunians, an Iapygian pre-Roman tribe living in Tavoliere plain, and as Capitanata, derived from ''Catapanata'', since the area was governed by a catepan as part of the Catepanate of Italy during the High Middle Ages. Its capital is the city of Foggia. Geography The province of Foggia can be divided in three parts: one centered on its capital called '' Tavoliere'', another along the Apennines named ''Daunian Mountains'' and the third on the spur of the boot-shaped Italian peninsula called ''Gargano''. The ''Tavoliere'' is an important agricultural area: grapefruit, olives, durum wheat and tomato are the chief products. It is called "the granary of Italy" because of its significant wheat production. ''Daunian Mountains'' lie along the border with Molise and Campania. Scattered with small villages, the ...

Fortore
The Fortore (Latin: ''Fertor'' or ''Frento'') is a river which flows through the provinces of Benevento, Campobasso and Foggia in southern Italy. It is long. The river rises from the slopes of Monte Altieri, which reaches above sea level. The Fortore, on the Adriatic side of the Apennines, collects the waters of four small streams about from San Bartolomeo in Galdo. From there it runs in a northerly direction through a narrow and twisting valley between Daunian Mountains. After , near Castelvetere in Val Fortore, it exits from the province of Benevento. In its lower course it forms the border between the provinces of Campobasso and Foggia. The Fortore flows into the Adriatic Sea not far from Lake Lesina. See also *Battle of Civitate The Battle of Civitate was fought on 18 June 1053 in southern Italy, between the Normans, led by the Count of Apulia Humphrey of Hauteville, and a Swabian-Italian- Lombard army, organised by Pope Leo IX and led on the battlefield by Gerard ...

Frentani Mountains
The Frentani were an Italic tribe occupying the tract on the southeast coast of the Italian peninsula from the Apennines to the Adriatic, and from the frontiers of Apulia to those of the Marrucini. They were bounded on the west by the Samnites, with whom they were closely connected, and from whom they were originally descended. Hence Scylax assigns the whole of this line of coast, from the frontiers of Apulia to those of Picenum, to the Samnites. Their exact limits are less clearly defined, and there is considerable discrepancy in the statements of ancient geographers: Larinum, with its territory (extending from the Tifernus (modern Biferno) to the Frento), being by some writers termed a city of the Frentani, while the more general opinion included it in Apulia, and thus made the river Tifernus the limit of the two countries. The northern boundary of the Frentani is equally uncertain; both Strabo and Ptolemy concur in fixing it at the river Sagrus (modern Sangro), while Pliny exten ...

Province Of Campobasso
A province is almost always an administrative division within a country or state. The term derives from the ancient Roman '' provincia'', which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term ''province'' has since been adopted by many countries. In some countries with no actual provinces, "the provinces" is a metaphorical term meaning "outside the capital city". While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities. Many have their own powers independent of central or federal authority, especially in Canada and Pakistan. In other countries, like China or France, provinces are the creation of central government, with very little autonomy. Etymology The English word ''province'' is attested since about 1330 and derives from the 13th-century Old French , which itself comes from the Latin word , which referred to the sphe ...

Basement (geology)
In geology, basement and crystalline basement are crystalline rocks lying above the mantle and beneath all other rocks and sediments. They are sometimes exposed at the surface, but often they are buried under miles of rock and sediment. The basement rocks lie below a sedimentary platform or cover, or more generally any rock below sedimentary rocks or sedimentary basins that are metamorphic or igneous in origin. In the same way, the sediments or sedimentary rocks on top of the basement can be called a "cover" or "sedimentary cover". Crustal rocks are modified several times before they become basement, and these transitions alter their composition. Continental crust Basement rock is the thick foundation of ancient, and oldest, metamorphic and igneous rock that forms the crust of continents, often in the form of granite. Basement rock is contrasted to overlying sedimentary rocks which are laid down on top of the basement rocks after the continent was formed, such as sandstone and ...

Hypocenter
In seismology, a hypocenter or hypocentre () is the point of origin of an earthquake or a subsurface nuclear explosion. A synonym is the focus of an earthquake. Earthquakes An earthquake's hypocenter is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture.''The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus.'' This occurs directly beneath the epicenter, at a distance known as the ''hypocentral depth'' or ''focal depth''. The focal depth can be calculated from measurements based on seismic wave phenomena. As with all wave phenomena in physics, there is uncertainty in such measurements that grows with the wavelength so the focal depth of the source of these long-wavelength (low frequency) waves is difficult to determine exactly. Very strong earthquakes radiate a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pull-apart Basin
In geology, a basin is a region where subsidence generates accommodation space for the deposition of sediments. A pull-apart basin is a structural basin where two overlapping (en echelon) strike-slip faults or a fault bend creates an area of crustal extension undergoing tension, which causes the basin to sink down. Frequently, the basins are rhombic or sigmoidal in shape. Dimensionally, basins are limited to the distance between the faults and the length of overlap.Frisch, Wolfgang, Martin Meschede, and Ronald C. Blakey. ''Plate tectonics: Continental drift and mountain building''. Springer, 2010. Pull-apart basins are also referred to as overlapping-tension-zones (OTZ). Mechanics and fault configuration The inhomogeneity and structural complexity of continental crust causes faults to deviate from a straight course and frequently causes bends or step-overs in fault paths. Bends and step-overs of adjacent faults become favorable locations for extensional and compressional st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Mechanism
The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault-related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can be derived from observing the pattern of "first motions", that is, whether the first arriving P waves break up or down. This method was used before waveforms were recorded and analysed digitally and this method is still used for earthquakes too small for easy moment tensor solution. Focal mechanisms are now mainly derived using semi-automatic analysis of the recorded waveforms. Moment tensor solutions The moment tensor solution is typically displayed graphically using a so-called ''beachball'' diagram. The pattern o ...
