Global warming upsets balance of Earth's tectonic plates


‘As sea water warms due to climate change, it expands; this rise in volume upsets the balance of tectonic plates, says a new study, adding that the Gangetic delta in South Asia is particularly vulnerable’

Global warming brings "increasing seismicity
 and probability of earthquake."
An earthquake is building up under the Gangetic delta, which could possibly be linked with the rapid rise in global temperatures leading to climate change, according to Kolkata-based geographer Sujib Kar.

“The relationship between temperature rise and rise in number of earthquakes is evident from two sets of data documented over a period of time,” Kar told thethirdpole.net. “If you look at the number of earthquakes of 5 or more in Richter scale from 2001 to 2015 in earthquake-prone areas, you will be able to comprehend the dynamics. This has been the period when the rise of global temperature was phenomenal.”

Global warming has been “increasing seismicity and probability of earthquake,” Kar – who teaches in Vidyasagar College, Kolkata – wrote in a paper Impact of global warming on the probable earthquake in the Bengal basin area with respect to the global scenario, which was published in the International Journal of Engineering Science Invention.

The latest identified threat is a subduction zone, where one section of earth’s crust, or a tectonic plate, is slowly thrusting under another. Instead of being under the ocean bed, this zone appears to be entirely under the land, which greatly multiplies the threat.
