Croscat
The Croscat () is a volcano in the comarca of Garrotxa, Catalonia, Spain. It is both the youngest and highest volcano in the Iberian Peninsula, with the last eruption dated back to about 14,000 years Before Present. The volcanic cone has a horseshoe shape, and its northeastern flank was quarried for volcanic gravel until the early 1990s, exposing the internal structure of the cone from top to bottom. The volcano is located in the Garrotxa volcanic field, a Quaternary volcanic field also known as Olot volcanic field, as part of the protected area of the Zona Volcànica de la Garrotxa Natural Park. Geology The cone has a height of and an elliptical base with a horseshoe shape, probably caused by the breaching of the western-side of the volcano as a result of the effusion of lava flows during the last eruptive phase of Croscat. A study published in 2011 at the Journal of Volcanology and Geothermal Research revealed that the Santa Margarida Volcano and the Croscat were the product ...

Garrotxa
Garrotxa () is a comarca (county) in Girona, Catalonia, Spain. Its population in 2016 was 55,999, more than half of them in the capital city of Olot. It is roughly equivalent to the historical County of Besalú. Geography Garrotxa borders the comarques of Ripollès, Osona, Selva, Gironès, Pla de l'Estany, Alt Empordà, and Vallespir. It includes the upper basin of the River Fluvià and the headwaters of the rivers Muga, Amer and Llémena. From both the human point of view and that of physical geography, the comarca has a clear division into two subcomarques. Extending north from the valley of the Fluvià, is Alta Garrotxa (Upper Garrotxa), while the southern part is sometimes called the comarca of Olot, after the capital city. The Fluvià flows toward the Mediterranean, and has a relatively small flow of water (1.07 m³/s at Olot). The high humidity of Garrotxa contrasts with that of the neighboring comarques. Annual rainfall is over 1000 mm (about 40 inches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Margarida Volcano
The Santa Margarida Volcano ( ca, Volcà de Santa Margarida) is an extinct volcano in the comarca of Garrotxa, Catalonia, Spain. The volcano has a perimeter of 2 kilometers and a height of 682 meters and is part of the Zona Volcànica de la Garrotxa Natural Park. The hermitage of Santa Margarida, after which the volcano was named, is inside the crater of the volcano. The building was destroyed in 1428 during the 1428 Catalonia earthquake and rebuilt in 1865. Geology A study published in 2011 at the Journal of Volcanology and Geothermal Research indicated that the Santa Margarida and Croscat volcanoes were the product of the same eruption event 11,500 years ago, alternating freatomagmatic activity, between water and magma, and magmatic activity.

Catalan Transversal Range
The Catalan Transversal Range (''Serralada Transversal'') is a system of minor mountain ranges at the eastern end of the Pre-Pyrenees, between the Osona and Garrotxa comarques. The existence of the Catalan Transversal Range has made communications in the northern areas of Catalonia difficult in the past, especially between Northeastern Catalonia ( Catalan Coastal Depression, with cities like Girona, Figueres and La Jonquera) and Western Catalonia ( Catalan Mediterranean System; Lleida, Cervera and further west to Aragón), a problem that has been partly solved with the development of the Eix Transversal. Description The Catalan Transversal Range is made up of a series of mountains running in a NW / SE axis between the Pyrenees, the Sub-Pyrenees, the Catalan Pre-Coastal Range and the northern end of the Catalan Coastal Depression. The highest point is at Puigsacalm, 1.515 m. Its most characteristic feature is a small region of volcanic origin near Olot, Garrotxa. There are ...

Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane (mathematics), plane angle in which one Turn (geometry), full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI Brochure, SI brochure as an Non-SI units mentioned in the SI, accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Iranian calendar, Persian calendar and the Babylonian calendar, used 360 days for a year. ...

Generalitat Of Catalonia
The Generalitat de Catalunya (; oc, label=Aranese, Generalitat de Catalonha; es, Generalidad de Cataluña), or the Government of Catalonia, is the institutional system by which Catalonia politically organizes its self-government. It is formed by the Parliament of Catalonia, the Presidency of the Generalitat de Catalunya, and the Executive Council of Catalonia (also very often referred to as ''Govern'', "Government"). Its origins are in the 13th century when permanent councils of deputies (deputations) were created to rule administration of the Courts of the different realms that formed the Crown of Aragon which gave birth to the Deputation of the General of the Principality of Catalonia (1359), the Deputation of the General of the Kingdom of Aragon (1362) and the Deputation of the General of the Kingdom of Valencia (1412). The modern Generalitat was established in 1931, as the institution of self-government of Catalonia within the Spanish Republic. Remaining in exile after t ...

Concession (contract)
A concession or concession agreement is a grant of rights, land or property by a government, local authority, corporation, individual or other legal entity. Public services such as water supply may be operated as a concession. In the case of a public service concession, a private company enters into an agreement with the government to have the exclusive right to operate, maintain and carry out investment in a public utility (such as a water privatisation) for a given number of years. Other forms of contracts between public and private entities, namely lease contract and management contract (in the water sector often called by the French term ''affermage''), are closely related but differ from a concession in the rights of the operator and its remuneration. A lease gives a company the right to operate and maintain a public utility, but investment remains the responsibility of the public. Under a management contract the operator will collect the revenue only on behalf of the govern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olot
Olot () is the capital city of the ''comarca'' of Garrotxa, in the Province of Girona, Catalonia, Spain. The city is known for its natural landscape, including four volcanoes scattered around the city center. The municipality is part of the Zona Volcànica de la Garrotxa Natural Park. Olot is also well known for its cultural activity, with historical art movements like Olot school or factories of religious imagery, which contributed to the location in the city of the main Design and Arts & Crafts school of the province of Girona, the Escola d'Art i Superior de Disseny d'Olot. Between 1911 and 1969, Olot was linked to Girona by the narrow gauge Olot–Girona railway. The line has since been converted into a greenway. Etymology The etymology of Olot is not clear and there are several hypotheses. According to the ''Crònica Universal de Catalunya'', Olot was founded by Ulo, former king of the dynasty of Atlanteans, (then called Siculus), with the name of ''Ulot.'' Another theor ...

Landfill
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

Lapilli
Lapilli is a size classification of tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. ''Lapilli'' (singular: ''lapillus'') is Latin for "little stones". By definition lapilli range from in diameter. A pyroclastic particle greater than 64 mm in diameter is known as a volcanic bomb when molten, or a volcanic block when solid. Pyroclastic material with particles less than 2 mm in diameter is referred to as volcanic ash. Formation Lapilli are spheroid-, teardrop-, dumbbell- or button-shaped droplets of molten or semi-molten lava ejected from a volcanic eruption that fall to earth while still at least partially molten. These granules are not accretionary, but instead the direct result of liquid rock cooling as it travels through the air. Lapilli tuffs are a very common form of volcanic rock typical of rhyolite, andesite and dacite pyroclastic eruptions, where thick layers of lapilli can be deposited during a ...
