Pithecusae
Ischia ( , , ) is a volcanic island in the Tyrrhenian Sea. It lies at the northern end of the Gulf of Naples, about from Naples. It is the largest of the Phlegrean Islands. Roughly trapezoidal in shape, it measures approximately east to west and north to south and has about of coastline and a surface area of . It is almost entirely mountainous; the highest peak is Mount Epomeo, at . The island is very densely populated, with 62,000 residents (more than 1,300 inhabitants per square km). Ischia is also well known for its thermal water and thermal gardens used since ancient times. Its volcanic nature makes Ischia one of the largest spas in Europe. Ischia's thermal waters are alkaline. Already the first Euboic settlers (8th century BC), as evidenced by the numerous archaeological finds found in the site of Pithecusa and preserved in thArchaeological Museum of Villa Arbustoin Lacco Ameno, appreciated and used the waters of the island's thermal springs. The Greeks, in fact, used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procida
Procida (; nap, Proceta ) is one of the Flegrean Islands off the coast of Naples in southern Italy. The island is between Cape Miseno and the island of Ischia. With its tiny satellite island of Vivara, it is a ''comune'' of the Metropolitan City of Naples, in the region of Campania. Etymology The island derives its name from the Latin name ''Prochyta''. Προχύτη/Prochýtē means 'poured out' in Ancient Greek. According to another theory, ''Prochyta'' comes from the Ancient Greek verb ''prokeitai'', meaning 'it lies forth', because of the appearance of the island seen from the sea. Geography Procida is located between Capo Miseno and the island of Ischia. It is less than . Its coastlines, very jagged, are . The ''Terra Murata'' hill is the highest point on the island (). Geologically, Procida was created by the eruption of four volcanoes, now dormant and submerged.

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horst (geology)
In physical geography and geology, a horst is a raised fault block bounded by Fault (geology), normal faults. Horsts are typically found together with Graben, grabens. While a horst lifted or remains stationary, the grabens on either side Subsidence, subside. This is often caused by Extensional tectonics, extensional forces pulling apart the crust. Horsts may represent features such as plateaus, mountains, or ridges on either side of a valley. Horsts can range in size from small fault-blocks, up to large regions of stable continent that have not been not folded or warped by tectonic forces. The word ''Horst'' in German language, German means "mass" or "heap," and was first used in the geological sense in 1883 by Eduard Suess in ''The Face of the Earth.''Originally published in 1883 in German as "Das Antlitz der Erde", translated and published in English in 1904 Geomorphology Horsts may have either symmetrical or asymmetrical cross-sections. If the normal faults to either side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Trachyte
Trachyte () is an extrusive igneous rock composed mostly of alkali feldspar. It is usually light-colored and aphanitic (fine-grained), with minor amounts of mafic minerals, and is formed by the rapid cooling of lava enriched with silica and alkali metals. It is the volcanic equivalent of syenite. Trachyte is common wherever alkali magma is erupted, including in late stages of ocean island volcanismMacDonald 1983, pp. 51-52 and in continental rift valleys, above mantle plumes,Philpotts and Ague 2009, pp. 390-394 and in areas of back-arc extension. Trachyte has also been found in Gale crater on Mars. Trachyte has been used as decorative building stone and was extensively used as dimension stone in the Roman Empire and the Republic of Venice. Chemical composition Trachyte has a silica content of 60 to 65% and an alkali oxide content of over 7%. This gives it less SiO2 than rhyolite and more (Na2O plus K2O) than dacite. These chemical differences are consistent with the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Naples
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.

Campi Flegrei
The Phlegraean Fields ( it, Campi Flegrei ; nap, Campe Flegree, from Ancient Greek 'to burn') is a large region of supervolcanic calderas situated to the west of Naples, Italy. It was declared a regional park in 2003. The area of the caldera consists of 24 craters and volcanic edifices; most of them lie under water. Hydrothermal activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are also effusive gaseous manifestations in the Solfatara crater, the mythological home of the Roman god of fire, Vulcan. This area is monitored by the Vesuvius Observatory. It is considered a supervolcano. The area also features bradyseismic phenomena, which are most evident at the Macellum of Pozzuoli (misidentified as a temple of Serapis): bands of boreholes left by marine molluscs on marble columns show that the level of the site in relation to sea level has varied.

Complex Volcano
A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. Stratovolcanoes can also form a large caldera that gets filled in by a lava dome, or else multiple small cinder cones, lava domes and craters may develop on the caldera's rim. Although a comparatively unusual type of volcano, they are widespread in the world and in geologic history. Metamorphosed ash flow tuffs are widespread in the Precambrian rocks of northern New Mexico, which indicates that caldera complexes have been important for much of Earth's history. Yellowstone National Park is on three partly covered caldera complexes. The Long Valley Caldera in eastern California is also a complex volcano; the San Juan Mountains in southwestern Colorado are formed on a group of N ...

Serrara Fontana
Serrara Fontana is a ''comune'' (municipality) on the Ischia island, in the Metropolitan City of Naples of the Italian region Campania. It is the highest and the smallest ''comune'' of the island. It was created by the union of the former villages of Serrara and Fontana. Its territory comprises several small villages: Noia, Calimera, Ciglio, Succhivo, Sant'Angelo, located on different elevations from the mountain to the sea. Serrara Fontana borders the following municipalities: Barano d'Ischia, Casamicciola Terme, Forio. German chancellor Angela Merkel and her husband spend their summer vacation in the region on a regular basis. |
Lacco Ameno
Lacco Ameno ( nap, U Làcchë) is a town and ''comune'' situated in the northwest of the island of Ischia, in the Metropolitan City of Naples off the west coast of Italy. The town has a population of around 4,800 inhabitants. It is located at the feet of Mount Epomeo, facing the sea. The name most likely derives from the Greek ''lakkos'', meaning "stone". The name ''ameno'' was added to the official name in 1862. On July 28, 1883, Lacco Ameno was severely damaged by an earthquake; together with the neighboring town of Casamicciola, the earthquake claimed over 2,300 victims. 269 houses, about 69% of the entire building fabric, were completely destroyed, and only 18 buildings remained undamaged. However, this could not stop the change from a fishing village to a health resort with thermal springs. The Italian publisher Angelo Rizzoli made Lacco Ameno a place for the international jet set by building several hotels in the 1950s and 1960s. In 1962 he also donated to the only hospital ...

Forio
Forio (known also as ''Forio of Ischia'') is a town and ''comune'' of c. 17,000 inhabitants in the Metropolitan City of Naples, southern Italy, situated on the island of Ischia. Overview Its territory includes the town of Panza, the only ''frazione'' of Forio and of the island of Ischia. Panza has always been an independent village since the 16th century when a first governmental organization was introduced on the island. In the 1975 the inhabitants of Panza tried to become an independent ''comune'' but the referendum, claimed by the inhabitants of Forio, was denied by the Campania's Regional Government. There are numerous coastal watchtowers, built from the Middle Ages against Saracen and African pirates raids.
