Research To Carry Out Research On The Link Between Geological Hazards And Climate

Although many experts feel that volcano eruptions and earthquakes are caused by climate change, they do not have much proof on this. On the other hand, experts have enough proofs that we must take this warning seriously.

Scientists are now calling for a detailed research to be carried out to find out if earthquakes, landslides, volcanoes and tsunamis could be triggered by the rising problem of global warming.

They said that the cause behind changes in geological activity could be traced back to the significant warming of the atmosphere in the past years.

Some of the experts even concluded that the present levels of global warming are responsible for landslides and rockfalls in the mountainous regions.

The climate modeler at the Met Office Hadley Centre in Exeter, Richard Betts said that that was a new area of academic research with potentially interesting implications. He also suggested the possibility of the links between these events and climate change.

According to him, we are likely to see impacts if we do not get a considerable amount of climate change.

He also pointed out that there was no solid proof that the present levels of global warming is influencing the earthquake that took place in China that caused the death of hundreds of people. He also said that there was no proof that the eruption of volcanoes in Iceland that prevented flights across Europe as caused by climatic change.

According to experts, hazards like earthquakes could be caused by global warming because of the way it could move a huge amount of mass around the surface of the Earth. Even the melting of glaciers and the rising of sea levels shift the distribution of a lot of water, which increases the underground pressure responsible for causing ruptures and seismic shifts. 

The crust of the Earth can sometimes be so weak that even tiny changes in surface pressure caused by heavy rain, snowfall, shifting tides, tropical storms, etc can cause earthquakes.

Bill McGuire, the chief of the Benfield Hazard Research suggested that in order to reduce the risk and increase our knowledge, a focused research must be advocated. The Intergovernmental Panel on Climate Change (IPCC) was also strongly exhorted to address more clearly in future assessments on the effects of anthropogenic climate change.

Last year, after a special meeting, the papers on the subject were published in a journal. It contained researches on impact of rising temperatures on earthquakes, volcanoes, etc and studies on whether the gas released from undersea deposits (gas hydrates) could activate tsunamis and landslides.
