Vesuvius ITALY
Mount Vesuvius (in Italian Monte Vesuvio and in Latin Mons Vesuvius) is a stratovolcano east of Naples, Italy. It is the only volcano on the European mainland to have erupted within the last hundred years, although it is not currently erupting. The two other volcanoes in Italy, (Etna and Stromboli) are located on islands.
Mount Vesuvius is on the coast of the Bay of Naples, about nine kilometres (six miles) east of Naples and a short distance from the shore. It is conspicuous in the beautiful landscape presented by that bay, when seen from the sea, with Naples in the foreground.
Mount Vesuvius is best known for its eruption in AD 79 that led to the destruction of the Roman cities of Pompeii and Herculaneum and the death of 10,000 to 25,000 people. It has erupted many times since and is today regarded as one of the most dangerous volcanoes in the world because of the population of 3,000,000 people living nearby and its tendency towards explosive (Plinian) eruptions. It is the most densely populated volcanic region in the world. Mount Vesuvius was regarded by the Greeks and Romans as being sacred to the hero and demigod Heracles/Hercules, and the town of Herculaneum, built at its base, was named after him.
Mud Volcanoes AZERBAIJAN
The term mud volcano or mud dome is used to refer to formations created by geo-excreted liquids and gases, although there are several different processes which may cause such activity. Temperatures are much cooler than igneous processes. The largest structures are 10 km in diameter and reach 700 metres in height.
About 20% of released gases are methane, with much less carbon dioxide and nitrogen emitted. Ejected materials often are a slurry of fine solids suspended in liquids which may include water (frequently acidic or salty) and hydrocarbon fluids.
Djavolja Varos, SERBIA
Djavolja Varos (Serbian Cyrillic: Ђавоља варош, meaning "Devil's Town") is a peculiar rock formation, located in south Serbia on the Radan Mountain near Kuršumlija. It features 202 exotic formations described as earth pyramids or "towers", as the locals refer to them. They are 2-15 m tall and 4-6 m wide at the base. These formations were created by strong erosion of the soil that was scene of intense volcanic activity millions of years ago. [1] Most of the towers have "caps" or "heads" of andesite, which protect them from further erosion.[2]
Since 1959, Đavolja Varoš has been protected by the state and a 1995 decision of the Serbian Government declared it a major natural monument subject to category one protection.[3]
A natural spring is located beneath the formations and has a high mineral concentration. There are two springs: Đavolja voda (Devil’s Water), with extremely acidic water (pH 1.5) and high mineral concentration (15 g/l of water), and Crveno vrelo (Red Well).[3]
