All you need to know about Volcanoes


The term volcano is a natural phenomenon that ruptures and happens majorly when the earth crust let’s hot lava or various gases escape from the magma down to the earth’s surface.

Most of these volcanoes tend to occur because the earth is divided by more than 10 tectonic plates, and it converges or divulge in this process volcano could erupt. Volcanoes that are not plate boundaries are known or termed to be mantle plumes, for reference in Hawaii the postulated rise from upwelling diapirs with magma from the core–mantle that is about 3,000-3500 km deep in the Earth. Volcanoes are do not erupt where there are two tectonic plates slide against one another.

Volcanoes pose a threat to living things around as it causes health and environmental pollution. The fumes and lava that gushes out of it is hazardous, and could cause skin reaction and harmful for breathing or inhalation. The process at which a volcano disturbs nature and it’s surrounding

  • The ozone layer wears out
  • There is a restriction on areas likely to have volcanic eruption.
  • Reduction of the sun and depletion of heat radiation.
  • Some kind of volcanoes could cause famine.
  • Some extreme eruptions could cause the release of Sulfur acid from the sky.

The study of volcanoes are done by some group of person’s known as volcanologist. With study volcanoes are differentiated they are Active or Dormant Volcano.


Active Volcano

Study show the span at which point volcano erupts is estimated at months and in some cases could take years(thousand) for a single eruption. Given this kind of estimate and the span of human existence it could be the volcano is dormant but it is fully active. A volcano that is active can be said to be close to eruption when case of reoccurring minimal earthquake at a little magnitude is witnessed or emission of strange gases.

With various research scientifically a volcano is said to be active if it has erupted at least in the past ten thousand years, then it is considered an active volcano and most volcanoes can be seen in the Pacific ring fire.

Dormant Volcano

Although not much talked about but the dormant Volcano and the extinct one are almost same and could hardly be differentiated as they are both classified based on there inactivity. The dormant Volcano on this case was explained by scientists as a volcano that has long-lost record of eruption and it’s Magma has lost supply and also the environs are most likely encroached by humans without fear of a future eruption.


Some volcano eruption around the world

  • Mount Yasur, 111 years
  • Mount Etna, 109 years
  • Stromboli, 108 years
  • Santa Maria, 101 years
  • Sangay 94 years

And some others in Asia and Australia.

Volcanoes are natural but also are hazards to mankind evolution has seen it’s destruction of lives and property even cities and towns are not left out an example of such case was the eruption of the Vesuvius volcano that claimed a Roman city(Pompeii) leaving it with lava filled. Keep off from volcanic areas at least 5 km off it to ensure a safe living and peace.
