Possible causes of volcanic activity
Possible causes of volcanic activity
In recent years, volcanic activity on the planet has risen sharply. The earth literally smokes from dozens of active volcanoes. Today there are active volcanoes in countries such as Iceland, Hawaii, Indonesia, Mexico, the Philippines, Papua New Guinea, Russia, Japan and many others. Many volcanoes – not just awe-inspiring show, they bring harm to people, sometimes there are victims volcanoes often occurs evacuation. Because of this, many people think – Does of volcanoes eruptions season? Amazing but this “season” may have. Volcanoes do not distinguish between seasons, but there may be other factors that influence the activity of their eruptions.
Eruption, caused by change the speed of rotation of the planet
Rotation of the planet has a direct impact on the change of the seasons, but the Earth’s rotation is associated with less significant factors – these include the activity of volcanoes. These factors contribute to the fact that the speed of rotation of the Earth and the gravitational force between the Earth and the Moon, change. This, in turn, influences the length of the day – day length can vary in milliseconds. But even these small changes can affect the processes occurring inside the planet.Recently, researchers have come to an interesting conclusion. It was established that since IXX century significantly changed the speed rotation of the Earth, and this has affected the volcanic activity. The authors proved by research that in the period from 1830 to 2014, the rate of rotation of the Earth has decreased, and this influenced the rapid increase the number of volcanic eruptions. These findings were published in the journal Terra Nova. By decreasing the speed of rotation of the Earth, releases massive amounts of energy per year – 120,000 Peta Joules. It’s so much energy that it is more than enough for lighting and fuel are US throughout the year. All of this energy goes into the earth, and this affects the volcanoes.Release the energy changes the electromagnetic field of the Earth, and this contributes to disturbance the magma. Magma – fluid in the perturbed state, it rises to the surface, causing volcanic activity. This is not the only factor influencing the volcanic activity.
Eruption caused by climate change
It’s no secret that the temperature on our planet is constantly increasing, it causes the melting of glaciers and sea level rise. According Cryptologic Research, the melting of glaciers in the past caused a significant surge in volcanic activity. Studies conducted in the 1970s mathematically prove that the melting of glaciers led to frequent volcanic eruptions. From this comes that there is a direct correlation between the change temperature of the earth and ocean level with volcanic activity.
Eruption due to ice melting
Nowadays there is a tendency to an increase in the melting of Antarctic glaciers. This has a direct impact on the Earth’s crust. Polar glaciers are very heavy. Every year, as a result of melting ice is less than about 40 billion tons. Because of it, the pressure on the ice crust decreases – she bends and cracks. Apparently, the volcanic activity will increase in proportion to the melting glaciers. However, the connection between the melting of glaciers and volcanic activity is still only a hypothesis; it has not yet been proven by scientific research.
