1456 Central Italy Earthquakes
On December 5, the largest earthquake to occur on the Italian Peninsula struck the Kingdom of Naples. The earthquake had an estimated moment magnitude of 7.19–7.4 , and nucleated near the town of Pontelandolfo in present-day Province of Benevento, central Italy. Earning a level of XI (''Extreme'') on the Modified Mercalli intensity scale, the earthquake caused widespread destruction in central and southern Italy. An estimated 30,000–70,000 people were killed. It was followed by two strong 7.0 and 6.0 earthquakes to the north on December 30. Tectonic setting The central Italian Peninsula is dominated by active extensional tectonics, forming the Apennine Mountains. The mountain range formed during the Miocene and Pliocene due to the subduction of the Adriatic Plate beneath the Eurasian Plate. The resulting subduction formed a fold and thrust belt. During the Quaternary, thrust tectonics gave way to extensional tectonics, with the development of a zone of normal faulting runn ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

1688 Sannio Earthquake
The 1688 Sannio earthquake occurred in the late afternoon of June 5 in the province of Benevento of southern Italy. The Moment magnitude scale, moment magnitude is estimated at 7.0, with a Mercalli intensity of XI. It severely damaged numerous towns in a vast area, completely destroying Cerreto Sannita and Guardia Sanframondi. The exact number of victims is unknown, although it is estimated to total approximately 10,000. It is among the most destructive earthquakes in the history of Italy. Earthquake The earthquake occurred in the southern and central part of the Apennines, an earthquake-prone area where several large Fault (geology), faults are present, and where extensional tectonics phenomena are common due to the collision of the African Plate with the Eurasian Plate. The earthquake was preceded by lighter earthquakes starting in February 1688 and by a series of foreshocks in the days before the main shock. It was followed by aftershocks lasting at least until December of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irpinia
Irpinia (Modern Latin ''Hirpinia'') is a geographical and cultural region of Southern Italy. It was the inland territory of the ancient ''Hirpini'' tribe, and its extent matches approximately today's province of Avellino. Geography The territory is largely mountainous, with an intricate network of hills and valleys and a predominantly limestone Karst topography. To the north-east, however, the rocks are mostly sandstone, and the land's elevation is relatively lower. Irpinia is centred on the section of the Apennines which spans from the northern to the springs of the Sele River; the highest peak is Mount Avella (1,591 m). To the south are the Picentini Mountains, which include the highest peak of the region, Mount Cervialto (1,809 m). Irpinia is bordered on the east by the Ofanto valley, while to the north it merges with Sannio and Daunia. History The name "Irpinia" derives from the Oscan word "hirpus", which means wolf, and the wolf remains Irpinia's symbol to t ...

Earthquake Rupture
In seismology, an earthquake rupture is the extent of slip that occurs during an earthquake in the Earth's crust. Earthquakes occur for many reasons that include: landslides, movement of magma in a volcano, the formation of a new fault, or, most commonly of all, a slip on an existing fault. Nucleation A tectonic earthquake begins by an initial rupture at a point on the fault surface, a process known as nucleation. The scale of the nucleation zone is uncertain, with some evidence, such as the rupture dimensions of the smallest earthquakes, suggesting that it is smaller than 100 m while other evidence, such as a slow component revealed by low-frequency spectra of some earthquakes, suggest that it is larger. The possibility that the nucleation involves some sort of preparation process is supported by the observation that about 40% of earthquakes are preceded by foreshocks. However, some large earthquakes, such as the M8.6 1950 India - China earthquake., have no foreshocks and it re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epoch (geology)
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define gl ...

Continental Collision
In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is only known to occur on Earth. Continental collision is not an instantaneous event, but may take several tens of millions of years before the faulting and folding caused by collisions stops. The collision between India and Asia has been going on for about 50 million years already and shows no signs of abating. Collision between East and West Gondwana to form the East African Orogen took about 100 million years from beginning (610 Ma) to end (510 Ma). The collision between Gondwana and Laurasia to form Pangea occurred in a relatively brief interval, about 50 million years long.
