And what about of that island that emerged from the sea. Amazing!

Least populated area yet there are hundreds of casualties.  Nature doesn't care where you worship.

Unfortunately, since two days ago there are small earthquakes around... is nature, nobody can stop it.

Apparently islands like that come and go depending on the weather.  Sea floor must be very unstable there.

 

And now that same island is passing gas.  The flammable kind.

  • You mean something like methane?  The sea floor in that area must be like a muskeg, full of rotted organic matter.  All that nice gas is a major greenhouse gas.

    No mention of methane in the news report.

  • Well, unless it is going to turn into an active volcano can you suggest any other gas likely?  Jibes with the idea that these islands come and go in bad weather.  A big ball of methane is consolidated, forces the top layer of the sea floor to the surface, exhales and the sea floor subsides.

    I don't know what gas is spewing out of this 'mud' volcano.  They mentioned it, but I wasn't paying that much attention to it.  I just know they didn't mention methane.

    Geologists think the new island, named Zalzala Koh, is made of erupted mud, spewed from the seafloor when either trapped gases escaped or subsurface water was violently expelled.

     

    The new island could be a mud volcano. Mud volcanoes form when hot water underground mixes with sediments and gases such as methane and carbon dioxide. If the noxious slurry finds a release valve, such as a crack opened by earthquake shaking, a mud volcanoexternal-link.png erupts, said James Hein, a senior scientist with the U.S. Geological Survey in Santa Cruz, Calif, said in an earlier interview. Geologists from the Pakistan Navy report that Zalzala Koh is releasing flammable gas. But seafloor sediments commonly hold methane-producing bacteria, so the possible methane coming from the island isn't a clincher to its identity.

     

    Shaking from the powerful Sept. 24 earthquake could have also loosened the seafloor sediments offshore of Pakistan, jiggling them like jelly. The great rivers coming down from the Himalayas dump tons of water-saturated sediment into the Arabian Sea every year. The new island could be a gigantic example of a liquefaction blow, when seismic shaking makes saturated sediments act like liquid and trapped water suddenly escapes, Michael Manga, a geophysicist at the University of California, Berkeley, told LiveScience last week

  • Yes, and with global warming the Himalaya annual melt will be getting less and less as the ice packs and glaciers disappear.  Soon a few billion people will be looking for water.  (Geologically soon, that is.).
