Strohn
Strohn is an ''Ortsgemeinde'' – a municipality belonging to a ''Verbandsgemeinde'', a kind of collective municipality – in the Vulkaneifel district in Rhineland-Palatinate, Germany. It belongs to the ''Verbandsgemeinde'' of Daun, whose seat is in the like-named town. Geography Location The municipality lies in the Vulkaneifel, a part of the Eifel known for its volcanic history, geographical and geological features, and even ongoing activity today, including gases that sometimes well up from the earth. Strohn lies south of Gillenfeld and the Pulvermaar, a local volcanic crater lake, on the river Alf’s left bank. Constituent communities The following hamlets and homesteads belong to Strohn: Altheck, Buchholz, Dornheck, Herrenbüsch, Sprink, Tannenhof and Trautzberg. Vulcanism The surrounding area is characterized by the Eifel’s vulcanism. Particularly worthy of mention is the Strohner Märchen, a small maar that has almost dried up (''Märchen'' here is a dimi ...

Alf (river)
The Alf is a small river in Rhineland-Palatinate, Germany, a left tributary of the Moselle. It rises in the Eifel, near Darscheid, east of Daun. The Alf flows south through Mehren, Gillenfeld and Bausendorf, where it turns east to flow into the Moselle at the village of Alf. Geography Course The Alf rises about northeast of Hörscheid in the Volcanic Eifel. From its source at a height of , the Alf initially flows in a southerly direction to the village of Darscheid, from which it flows to the east through the villages of Gillenfeld and Strohn. The next section of the Alf, to Bausendorf, is very winding; it then turns towards the east and cuts through the south of the forest of Kondelwald, passing the villages of Kinderbeuern and Bengel. Around beyond Bengel it changes course abruptly and swings north. A ridge prevents it from flowing further east unto the Moselle, here just away. After breaking through the Moselle Hills the Alf finally reaches the Moselle at Alf (Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulkan Eifel
The Volcanic Eifel or Vulkan Eifel (german: Vulkaneifel) is a region in the Eifel Mountains in Germany that is defined to a large extent by its volcanic geological history. Characteristic of this volcanic field are its typical explosion crater lakes or maars, and numerous other signs of volcanic activity such as volcanic tuffs, lava streams and volcanic craters like the Laacher See. The Volcanic Eifel is still volcanically active today. One sign of this activity is the escaping gases in the Laacher See. Geographical location The Volcanic Eifel stretches from the Rhine to the Wittlich Depression. It is bordered in the south and southwest by the South Eifel, in the west by Luxembourg and Belgian Ardennes and in the north by the North Eifel including the Hohes Venn. To the east the Rhine forms its geographical boundary, with no volcanicity immediately beyond it. The Volcanic Eifel is divided into three natural regions: * Volcanic West Eifel ( Manderscheid, Daun, Gerolstein, Ober ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulkaneifel
Vulkaneifel () is a district (''Kreis'') in the northwest of the state Rhineland-Palatinate, Germany. It is the least densely populated district in the state and the fourth most sparsely populated district in Germany. The administrative centre of the district is in Daun. Neighboring districts are Euskirchen (North Rhine-Westphalia), Ahrweiler, Mayen-Koblenz, Cochem-Zell, Bernkastel-Wittlich, and Bitburg-Prüm. Location The county of Vulkaneifel lies in the western part of the eponymous region which lies at heights between 150 and 700 metres above sea level. As a result of former volcanism numerous mineral springs (''Sauerbrunnen'') have formed. The Kyll flows through the county from north to south. The German Wildlife Route and the German Volcano Route also cross the county as does the Eifelsteig hiking trail. History The district was created in 1815 when the Eifel became part of Prussia. As most of the local industries had their traditional markets in France, the distri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulvermaar
The Pulvermaar is a water-filled maar that lies southeast of Daun in the German state of Rhineland-Palatinate. Together with the Holzmaar it is one of the Gillenfeld maars. Description A tuff site in the bog formations of the neighbouring Strohner Maar is ascribed to the Pulvermaar and is therefore older than the Pulvermaar. Early pollen analyses of the bogs gave an age for the tuff site – and thus the Pulvermaar – of about 10,050 years. More recent studies show, however, underwater terraces at greater depth as well as ice wedges inside the tephra deposits, both of which suggest that the maar was formed during the last ice age, 20,000 to 30,000 years ago. Vulcanologists from the Smithsonian Institution estimate the last eruption of the Strohner Maar and Pulvermaar in 8,300 BC. The almost circular maar has steep funnel-shaped sides. The maar lake lies at a height of and, with a maximum depth of , is the deepest in the Volcanic Eifel. It has a diameter of about and surface ...

Maar
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. Notes: * According to German Wikipedia's ''"Maar"'' article, in 1544 in his book ''Cosmographia'', Sebastian Münster (1488–1552) first applied the word "maar" (as ''Marh'') to the Ulmener Maar and the Laacher See. See: Sebastian Münster, ''Cosmographia'' (Basel, Switzerland: Heinrich Petri, 1544)p. 341. From p. 341: ''"Item zwen namhafftiger seen seind in der Eyfel / einer bey de schloß Ulmen / und ein ander bey dem Closter züm Laich / die seind sere tieff / habe kein ynflüß aber vil außflüß / die nennet man Marh unnd seind fischreich."''

Volcanic Bomb
A volcanic bomb or lava bomb is a mass of partially molten rock (tephra) larger than 64 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. Because volcanic bombs cool after they leave the volcano, they are extrusive igneous rocks. Volcanic bombs can be thrown many kilometres from an erupting vent, and often acquire aerodynamic shapes during their flight. Bombs can be extremely large; the 1935 eruption of Mount Asama in Japan expelled bombs measuring 5–6 m (16-20 ft) in diameter up to from the vent. Volcanic bombs are a significant volcanic hazard, and can cause severe injuries and death to people in an eruption zone. One such incident occurred at Galeras volcano in Colombia in 1993; six people near the summit were killed and several seriously injured by lava bombs when the volcano erupted unexpectedly. On July 16, 2018, 23 people were injured on a tour boat near the Kilauea volcano as a result of a basketb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...
