Earthquakes can contribute to global warming by releasing greenhouse gases from the ocean floor. This finding suggests a natural source of greenhouse gases not previously considered. Research published in the journal Nature Geoscience, News reported.

Scientists have found evidence of a major earthquake in 1945 Arab north sea, emissions than 7 million m3 of methane (CH4) into the atmosphere. This finding suggests a natural source of greenhouse gases not previously considered. Research published in the journal Nature Geoscience,AccordingNewsreported.

But with little in the atmosphere, but CH4 is a greenhouse gas causing higher 20 times higher than CO2. Large amount of CH4 are stored in hydrate ice structure on the floor of the continental shelf around the earth.

Estimated 1.000 to 5.000 giga tonnes of carbon were stored in methane hydrate ice structure, more than the total annual emissions by burning fossil fuels.

After analyzing sediment samples taken from five Arab north sea 2007, group of scientists found signs of a chemical release for large-scale CH4, Historical documents record an earthquake intensity 8,1 magnitude happened nearby in 1945.

Dr. David Fischer from the University of Bremen, Germany says: “Based on a number of criteria, we see that the earthquake ruptured sediments, liberate gas trapped beneath”.

Currently methane hydrate was proposed as a promising energy source, but they are very expensive to exploit and dangers. They are stable on the ocean floor and will be freed if an earthquake, Tsunami.
