Climatic Changes After The Eruption of Tambora in 1815
Zhao, Shuran ; Soukupová, Jana (advisor) ; Bašta, Petr (referee)
Volcanic activities belongs to the most common natural events on this planet. They are as old as our planet. Some volcanoes have very long life cycle, their interval of eruptions can be up to tens or hundreds of thousands years. In general, the long interval the large eruption. The super-eruptions on VEI 8 are able to destroy the whole human civilization on the world. Fortunately this kind of eruptions is very rare from the human perspective.
Other weaker eruptions happen more frequently. Human civilization experienced an eruption of VEI 7 in 1815, which was the biggest eruption during last 10 000 years and led to global cooling and famine. That was the biggest volcanic eruption in human history, eruption of volcano Tambora in 1815.
Tambora during its eruption released a tremendous amount of magma and volcanic gases. It has been unsurpassed till now. It had severe consequences, many people were killed by the eruption but even more people died as a result of diseases or starvation related to eruption. In next 2 to 3 years after eruption, Northern Hemisphere was in an unstable condition. A huge amount of volcanic gases and ash released by this eruption was transported into stratosphere that led to global cooling. Just the cooling destroyed many fields and killed lots of people. So that year 1816 get a name as year without summer. In my work I collected information and data of weather during 1815 to 1817 around Northern Hemisphere to compare them and to find out whether the eruption changed the climate after 1815. Many sources recorded an unusual weather in North America, Asia and Europe. In these years, it was always cloudy and persistently rained. The Czech lands were also affected by this eruption. Many Czech sources recorded cold weather in 1815-1817 that related with widespread rise in price of agricultural products. It undoubtedly worsened the already grave situation.
Such these eruptions are big threat to human civilization. We cannot avoid them, but we can reduce the consequences to a minimum by monitoring volcanoes and their activities.
The aim of this work is describe the climatic changes accompanied with the big volcanic eruption of 1815 and its consequences. I am trying to restoring the details of volcanic eruption. My aim is to draw attention to the danger of volcanic activity and the importance of monitoring volcanoes.
