1783 Calabrian Earthquakes
The 1783 Calabrian earthquakes were a sequence of five strong earthquakes that hit the region of Calabria in southern Italy (then part of the Kingdom of Naples), the first two of which produced significant tsunamis. The epicenters form a clear alignment extending nearly 100 km from the Straits of Messina to about 18 km SSW of Catanzaro. The epicenter of the first earthquake occurred in the plain of Palmi. The earthquakes occurred over a period of nearly two months, all with estimated magnitudes of 5.9 or greater. Estimates of the total number of deaths lie in the range 32,000 to 50,000. Tectonic setting The southwestern part of Calabria and the eastern part of Sicily are areas of active crustal extension within the Siculo-Calabrian rift Zone. This 350 km long zone developed within the Apennine chain during the Pleistocene and takes up WNW–ESE directed extension.

Peak Ground Acceleration
Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an wikt:accelerogram, accelerogram at a site during a particular earthquake. Earthquake shaking generally occurs in all three directions. Therefore, PGA is often split into the horizontal and vertical components. Horizontal PGAs are generally larger than those in the vertical direction but this is not always true, especially close to large earthquakes. PGA is an important parameter (also known as an intensity measure) for earthquake engineering, The design basis earthquake ground motion (DBEGM) is often defined in terms of PGA. Unlike the Richter magnitude scale, Richter and Moment magnitude scale, moment magnitude scales, it is not a measure of the total seismic scales#Magnitude and intensity, energy (magnitude, or size) of an earthquake, but rather of how hard the earth shake ...

Messina
Messina (, also , ) is a harbour city and the capital of the Italian Metropolitan City of Messina. It is the third largest city on the island of Sicily, and the 13th largest city in Italy, with a population of more than 219,000 inhabitants in the city proper and about 650,000 in the Metropolitan City. It is located near the northeast corner of Sicily, at the Strait of Messina and it is an important access terminal to Calabria region, Villa San Giovanni, Reggio Calabria on the mainland. According to Eurostat the FUA of the metropolitan area of Messina has, in 2014, 277,584 inhabitants.

Sand Volcano
Sand boils or sand volcanoes occur when water under pressure wells up through a bed of sand. The water looks like it is boiling up from the bed of sand, hence the name. Sand volcano A sand volcano or sand blow is a cone of sand formed by the ejection of sand onto a surface from a central point. The sand builds up as a cone with slopes at the sand's angle of repose. A crater is commonly seen at the summit. The cone looks like a small volcanic cone and can range in size from millimetres to metres in diameter. The process is often associated with soil liquefaction and the ejection of fluidized sand that can occur in water-saturated sediments during an earthquake. The New Madrid Seismic Zone exhibited many such features during the 1811–12 New Madrid earthquakes. Adjacent sand blows aligned in a row along a linear fracture within fine-grained surface sediments are just as common, and can still be seen in the New Madrid area. In the past few years, much effort has gone into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Borgia
The House of Borgia ( , ; Spanish and an, Borja ; ca-valencia, Borja ) was an Italian-Aragonese Spanish noble family, which rose to prominence during the Italian Renaissance. They were from Valencia, the surname being a toponymic from the town of Borja, then in the Crown of Aragon, in Spain. The Borgias became prominent in ecclesiastical and political affairs in the 15th and 16th centuries, producing two popes: Alfons de Borja, who ruled as Pope Callixtus III during 1455–1458, and Rodrigo Lanzol Borgia, as Pope Alexander VI, during 1492–1503. Especially during the reign of Alexander VI, they were suspected of many crimes, including adultery, incest, simony, theft, bribery, and murder (especially murder by arsenic poisoning). Because of their grasping for power, they made enemies of the Medici, the Sforza, and the Dominican friar Girolamo Savonarola, among others. They were also patrons of the arts who contributed to the development of Renaissance art. The Borgia family s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
