801 Apennine Earthquake
An earthquake originating in the Central Apennines was felt in Rome and Spoleto on 29 April 801. It is reported in two independent contemporary sources, Einhard's ''Royal Frankish Annals'' and the ''Liber Pontificalis''. The information provided by the written sources has been augmented by archaeology. Both the ''Annals'' and the ''Liber'' date the event to 30 April according to contemporary Roman practice, whereby the day began at sundown. The ''Annals'' specify that it happened at the second hour of the night, which corresponds to 20:00 (8:00 p.m.) on 29 April by modern reckoning. The ''Annals'' record the event from the perspective of the Frankish king Charlemagne, who had been crowned Roman emperor on 25 December 800 and had left Rome on 25 April for Spoleto, where he was staying when the earthquake struck. They do not record the damage at Spoleto. Charlemagne was unharmed, but perhaps spooked. The quake was severe, with an estimated magnitude at Rome of VII–VIII on t ...

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triumphal Arch
A triumphal arch is a free-standing monumental structure in the shape of an archway with one or more arched passageways, often designed to span a road, and usually standing alone, unconnected to other buildings. In its simplest form, a triumphal arch consists of two massive Pier (architecture), piers connected by an arch, typically crowned with a flat entablature or Attic style, attic on which a statue might be mounted or which bears commemorative inscriptions. The main structure is often decorated with carvings, sculpted reliefs, and dedications. More elaborate triumphal arches may have multiple archways, or in a tetrapylon, passages leading in four directions. Triumphal arches are one of the most influential and distinctive types of ancient Roman architecture. Effectively invented by the Romans, and using their skill in making arches and vaults, the Roman triumphal arch was used to commemorate victorious generals or significant public events such as the founding of new Colonia ...

Primary Sources
In the study of history as an academic discipline, a primary source (also called an original source) is an artifact, document, diary, manuscript, autobiography, recording, or any other source of information that was created at the time under study. It serves as an original source of information about the topic. Similar definitions can be used in library science and other areas of scholarship, although different fields have somewhat different definitions. In journalism, a primary source can be a person with direct knowledge of a situation, or a document written by such a person. Primary sources are distinguished from ''secondary sources'', which cite, comment on, or build upon primary sources. Generally, accounts written after the fact with the benefit of hindsight are secondary. A secondary source may also be a primary source depending on how it is used. For example, a memoir would be considered a primary source in research concerning its author or about their friends charact ...

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 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 prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures ...

Tsunami
A tsunami ( ; from , ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give the false impression of ...

Landslide
Landslides, also known as landslips, rockslips or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Landslides are frequently made worse by human development (such as urban sprawl) and resource exploitation (such as mining and deforestation). Land degradation freque ...

Basilica Ulpia
The Basilica Ulpia was an ancient Roman civic building located in the Forum of Trajan. The Basilica Ulpia separates the temple from the main courtyard in the Forum of Trajan with the Trajan's Column to the northwest. It was named after Roman emperor Trajan whose full name was Marcus Ulpius Traianus. It became perhaps the most important basilica after two ancient ones, the Basilicas Aemilia and Julia. With its construction, much of the political life moved from the Roman Forum to the Forum of Trajan. It remained so until the construction of the Basilica of Maxentius and Constantine. Unlike later Christian basilicas, it had no known religious function; it was dedicated to the administration of justice, commerce and the presence of the emperor. It was the largest in Rome measuring . Design and construction The Basilica Ulpia was composed of a great central nave with four side aisles, two on each side of the nave. The short sides of the structure formed apses, while the main en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pippin The Short
the Short (; ; ; – 24 September 768), was King of the Franks from 751 until his death in 768. He was the first Carolingian to become king. was the son of the Frankish prince Charles Martel and his wife Rotrude. Pepin's upbringing was distinguished by the ecclesiastical education he had received from the Christian monks of the Abbey Church of St. Denis, near Paris. Succeeding his father as the Mayor of the Palace in 741, Pepin reigned over Francia jointly with his elder brother, Carloman. Pepin ruled in Neustria, Burgundy, and Provence, while his older brother Carloman established himself in Austrasia, Alemannia, and Thuringia. The brothers were active in suppressing revolts led by the Bavarians, Aquitanians, Saxons, and the Alemanni in the early years of their reign. In 743, they ended the by choosing Childeric III, who was to be the last Merovingian monarch, as figurehead King of the Franks.
