Volcanoes will spray more because of climate change

Global warming can increase the number of dangerous geological events such as volcanoes, earthquakes and landslides.

Telegraph said, in a number of articles published in the Philosophical Transactions of the Royal Society A, scientists at the University of London warned of the phenomenon of melting ice, sea level rise, strong storms and heavy rains that could work move to the earth's crust. These catastrophes may increase in both quantity and extent due to global warming. Even a small change in the environment can cause earthquakes or tsunamis.

Scientists have found evidence of the effects of climate change on geological activity in many places like the state of Alaska in the United States.

Bill McGuire, a researcher at the University of London, says when temperatures rise, melting glaciers and glaciers cause ocean water to rise.

When the water is still in the form of ice, the soil beneath the ice is subject to a certain amount of pressure. But if the ice melts, the ground will 'turn' on because there is no more pressure. In places like Greenland and Antarctica, the soil is under great pressure because the thickness of the ice reaches thousands of meters. In the worst case, if all the ice in the two places melted, the soil would pop up very strongly and cause an earthquake.

The increase in the number of earthquakes can cause landslides on the ocean floor - one of the phenomena that leads to tsunamis.

When ice blocks break, they can create a tsunami capable of reaching many places like New Zealand, Canada and Chile. The decline in the number of ice also stimulates volcanic eruption.

Due to melting ice, the mass of water in the oceans becomes bigger and "bends" the earth's crust. When the crust is bent, lava will erupt and cause volcanic and seismic activity in the coast or island.

Increased volcanic activity also increases the number of landslides and causes many impacts in places far away from volcanoes. For example, the latest volcanic eruption in Iceland caused fly ash throughout Europe and paralyzed aviation.

Professor McGuire says changes may occur in the next few decades or centuries, but not for a thousand years. Timing depends on many factors, such as sea level rise.
