CITIES OF THE UNDERWORLD There are many volcanos in the world‚ but one particular volcano called Mount Vesuvius is over thousands of years old. It was so powerful that it erupted over 50 times in total so far. When this volcano had its famous eruption‚ it buried the ancient roman city under a very large layer of ash from the volcano. During this event people who lived in the ancient roman city were trying to survive from this tragedy. Over two thousand people had died along with the city being

Thera‚ the volcanic caldera in Greece that violently erupted 3500 years ago spawning the myth of Atlantis‚ and wiping out most of the Minoan civilization‚ is deforming. Scientists suggest that this caldera‚ a crater-like volcano that has collapsed in the past‚ may erupt again‚ making the people of the island vulnerable. The deformation could cause many disasters such as tsunamis‚ earthquakes‚ and obviously eruptions. Scientists argue whether the volcanic caldera unrest is actually a threat to the

A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods‚ volcanic eruptions‚ earthquakes‚ tsunamis‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable

Premium Volcano Plate tectonics Convergent boundary
Introduction A volcano is an opening‚ or rupture‚ in a planet’s surface or crust‚ which allows hot magma‚ volcanic ash and gases to escape from the magma chamber below the surface. How is a volcano formed? Most volcanoes are formed by the movement of tectonic plates on the surface of the earth. These plates are basically huge pieces of rock that ‘float’ on the mantle (a layer of the earth that is sort-of liquid rock). The tectonic plates are in constant motion‚ albeit very slow motion. They sometimes

Premium Volcano Plate tectonics
Earthquake‚ shaking of the Earth’s surface caused by rapid movement of the Earth’s rocky outer layer. Earthquakes occur when energy stored within the Earth‚ usually in the form of strain in rocks‚ suddenly releases. This energy is transmitted to the surface of the Earth by earthquake waves. The destruction an earthquake causes depends on its magnitude and duration‚ or the amount of shaking that occurs. A structure’s design and the materials used in its construction also affect the amount of damage
