Laacher See
Laacher See (), also known as Lake Laach or Laach Lake, is a volcanic Volcanic crater lake, caldera lake with a diameter of in Rhineland-Palatinate, Germany, about northwest of Koblenz, south of Bonn, and west of Andernach. It is in the Eifel mountain range, and is part of the East Eifel volcanic field within the larger Volcanic Eifel. The lake was formed by a Plinian eruption approximately 13,000 years Before Present, BP with a Volcanic Explosivity Index (VEI) of 6, on the same scale as the Mount Pinatubo#1991 eruption, Pinatubo eruption of 1991. The Volcanic gas, volcanic discharge observable as mofettas on the southeastern shore of the lake is a sign of Dormant volcano, dormant volcanism. Description The lake is oval in shape and surrounded by high banks. The lava was quarried for millstones from the Roman period until the introduction of iron rollers for grinding grain. The water level has considerable rises and falls as the lake has no natural outlet. On the western side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahrweiler (district)
Ahrweiler () is a district in the north of Rhineland-Palatinate, Germany. It is bounded by (from the north and clockwise) the districts of Euskirchen (district), Euskirchen, Rhein-Sieg and the city of Bonn in the state of North Rhine-Westphalia, and the districts of Neuwied (district), Neuwied, Mayen-Koblenz and Vulkaneifel. History The region was conquered by the Roman Empire, Romans under Julius Caesar about 50 BC. Some hundred years later the Roman fort of Rigomagus (Gaulish for "king's field") was founded, later to become the city of Remagen. The Vinxtbach, a narrow brook and an affluent of the Rhine, was defined as the borderline between the Roman provinces of Germania superior and Germania inferior. There was originally a Roman villa here; the German suffix, "weiler", is from the Latin term "villare", meaning "land attached to a Roman villa, farm". Portions of a Roman aqueduct have also been found nearby. Many towns were first mentioned in the 9th century, among them Sinz ...

Mofetta
Mofetta (Italian from Latin ''mephītis'', a pestilential exhalation) is a name applied to a volcanic discharge consisting chiefly of carbon dioxide, often associated with other vapours, representing the final phase of volcanic activity. The Oxford Dictionary of English lists ''mofetta'' as an archaic term for the modern word fumarole. The word is used in the plural as ''mofette'', or, following the French fashion, ''mofettes''. The volcanic vents yielding the emanations are themselves called mofette. They are not uncommon in Auvergne and in the Eifel, notably on the shore of the Laacher See; whilst other examples are furnished by the Grotta del Cane, near Pozzuoli, the Valley of Death in Java, the Death Gulch in the Yellowstone Park and the series of mofette in Romania's Harghita and Covasna counties. Depending on the mineral content of the different vapours, mofette may be used for therapeutic purposes as well. As carbon dioxide is heavier than the air, patients c ...

Tectonic Plate
Plate tectonics (, ) is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. The model builds on the concept of , an idea developed during the first decades of the 20th century. Plate tectonics came to be accepted by geoscientists after seafloor spreading was validated in the mid-to-late 1960s. The processes that result in plates and shape Earth's crust are called ''tectonics''. Tectonic plates also occur in other planets and moons. Earth's lithosphere, the rigid outer shell of the planet including the crust and upper mantle, is fractured into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary (or fault): , , or . The relative movement of the plates typically ranges from zero to 10 cm annually. Faults tend to be geologically active, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Cenozoic Rift System
The European Cenozoic Rift System (ECRIS) is a long system of rifts formed in the foreland of the Alps as the lithosphere responded to the effects of the Alpine and Pyrenean orogenies. The system began to form during the Late Eocene and parts (particularly the Upper and Lower Rhine Grabens) remain seismically active today and are responsible for most of the larger earthquakes in Europe, north of the Alps. Extent The ECRIS consists of a series of rifts and associated transfer faults extending from the Mediterranean to the North Sea. Limagne Graben This north-south trending rift structure formed in the middle Eocene creating a lake that is now the Limagne plain. The main phase of subsidence continued until the Late Oligocene. The graben is controlled by faults on its western side and is filled with Cenozoic sediments up to 2 km thick. Bresse Graben The Bresse Graben lies to the east of the Limagne Graben. Rifting started during the Eocene, pausing from the Late Oligoce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handley Page Halifax
The Handley Page Halifax is a British Royal Air Force (RAF) four-engined heavy bomber of the Second World War. It was developed by Handley Page to the same specification as the contemporary twin-engine Avro Manchester. The Halifax has its origins in the twin-engine ''H.P.56'' proposal of the late 1930s, produced in response to the British Air Ministry's Specification P.13/36 for a capable medium bomber for "world-wide use." The H.P.56 was ordered as a backup to the Avro 679, both aircraft being designed to use the Rolls-Royce Vulture engine. The Handley Page design was altered to use four Rolls-Royce Merlin engines while the rival Avro 679 was produced as the twin-engine Avro Manchester which, while regarded as unsuccessful mainly due to the Vulture engine, was a direct predecessor of the Avro Lancaster. Both the Lancaster and the Halifax emerged as capable four-engine strategic bombers, thousands of which were used during the War. The Halifax performed its first flight on ...

Heinrich II Of Laach
Henry of Laach (in German: ''Heinrich von Laach'') was the first count palatine of the Rhine (1085/1087–1095), then within the area of Lower Lotharingia. Henry was the son of Herman I, count of Gleiberg. Henry was a follower of Henry IV, Holy Roman Emperor. He had lands in the southeastern Eifel and on the Moselle River. Most of the holdings of Hermann II, Count Palatine fell back to the emperor, when Hermann died without successor. The emperor named Henry count palatine of the Rhine and during the emperor's trip to Italy tasked Henry to hold interim judicial councils. Henry married Herman's widow, Adelaide of Weimar-Orlamünde (d. 1100). From this marriage, Henry may have taken control over some of her holdings along the Moselle. As a consequence, the geographic center of the palatinate moved towards the south. With his wife, Adelaide, Henry founded the Maria Laach Abbey Maria Laach Abbey (in German: ''Abtei Maria Laach'', in Latin: ''Abbatia Maria Lacensis'' or ''Ab ...

Maria Laach Abbey
Maria Laach Abbey (in German: ''Abtei Maria Laach'', in Latin: ''Abbatia Maria Lacensis'' or ''Abbatia Maria ad Lacum'') is a Benedictine abbey situated in Glees, on the southwestern shore of the Laacher See (Lake Laach), in the Eifel region of the Rhineland-Palatinate in Germany. It is a member of the Beuronese Congregation within the Benedictine Confederation. The abbey was built in the 11th-12th centuries and was originally known as "Abtei Laach" ("Abbatia Lacensis" or "Laach Abbey", meaning the "Lake Abbey") until 1862 when the Jesuits added the name "Maria". First Benedictine foundation Founded in 1093 as a priory of Affligem Abbey (in modern Belgium) by the first Count Palatine of the Rhine Heinrich II von Laach and his wife Adelaide of Weimar-Orlamünde, widow of Hermann II of Lotharingia, Laach became an independent house in 1127, under its first abbot, Gilbert.
