A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
There are five sources of data for analizing the impact of the volcano eruptions, which county is more prone to this disaster and how to take measures to prevent it.The data has to be combined together to get broad insights for informed decision making.
The data is orginally from The Smithsonian Institution
Therefore, with the help of data analysis and visualization, we can find trend about countries with most volcano occurences and look for measures to migitate against such disaster for future purposes.
In the volcano data (volcano.csv), 44.6% of all volcanic eruption occurences actually happened,other category includes volcanic eruption uncertain or there is unrest. United states with the highest number of volcanic eruption since year dated 1883 should be paid attention to. Particular places such as Oregon and California which have the highest occurence in the country should be given attention. Stratovolcano volcano type has the highest occurence from the year stated
