RashRashid Tabrez, the director-general of the Karachi-based National Institute of Oceanography, says the energy released by the seismic movements of these fault-lines activates inflammable gases in the seabed.Plate tectonics? In case you live in world you think is unrelated to geology. Image above is from NASA here,
"The seabed near the Makran coast has vast deposits of gas hydrates, or frozen gas having a large methane content," he explained.
"These deposits lay compressed under a sediment bed that is 300m-800m thick."
"When the plates along the fault-lines move, they create heat and the expanding gas blasts through the fissures in the earth's crust, propelling the entire sea floor to the surface." Tabrez, the director-general of the Karachi-based National Institute of Oceanography, says the energy released by the seismic movements of these fault-lines activates inflammable gases in the seabed.
Horizontal velocities, mostly due to motion of the Earth's tectonic plates, are represented on the map by lines extending from each site.
And about "gas hydrates" here:
As natural gas from shale becomes a global energy "game changer," oil and gas researchers are working to develop new technologies to produce natural gas from methane hydrate deposits. This research is important because methane hydrate deposits are believed to be a larger hydrocarbon resource than all of the world's oil, natural gas and coal resources combined. If these deposits can be efficiently and economically developed, methane hydrate could become the next energy game changer.I am waiting for environmentalists to condemn "Nature" or "Geology" or declare that this is somehow "man caused."
Enormous amounts of methane hydrate have been found beneath Arctic permafrost, beneath Antarctic ice and in sedimentary deposits along continental margins worldwide. In some parts of the world they are much closer to high-population areas than any natural gas field. These nearby deposits might allow countries that currently import natural gas to become self-sufficient. The current challenge is to inventory this resource and find safe, economical ways to develop it.
In any event, there is some concern that if a large amount of methane gas hydrate was release all at once there will be serious consequences.
On the other hand, the earth could get hit by a really big meteor or something. If it's not one damn thing it another as far as doomsday scenarios go. Or, as the poet put it:
Fire and Ice
By Robert Frost
Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
