The new land owes its existence to the mud to the volcano.

More than 260 people died, hundreds of thousands were left without shelter. At the same time, an island rose from the bottom of the country, which immediately became an object of general curiosity. Scientists however, they believe that the new land will not last long. “May be, a couple of months, says geophysicist Bill Barnhart of Geological US service. – It’s just a big pile of dirt that rose along with the seabed. “Similar islands are sometimes created so called mud volcanoes arising here and there around the light. Apparently, this case is no exception. Information agencies report that a Pakistani island suddenly appeared near port of Gwadar after the earthquake. It is 18-21 m high, wide – 91 m, length – 37 m, according to France Press. Some say he two steps from the coast, the other two kilometers. To the epicenter earthquakes – 400 km. Although the stones are visible in the photographs, Mr. Barnhart insists that basically the island is composed of silt from the sea bottom. On it they found a dead octopus and a lot of fish. Similar mud construction arose off the coast of Pakistan after earthquake in 2011. It lasted one or two months, and then it just washed away. Mud volcanoes are far from always give rise to land. Mr. Barnhart recalls California earthquake of 2010, after which large ones rose from the bottom carbon dioxide bubbles, but besides active gurgling, there wasn’t nothing interesting, no new islands. There is no doubt, Pakistani scientists will soon measure the island and tell how it is formed. So far, one can only assume that seismic waves generated by an earthquake forced some liquid material under the seabed expand. The bark cracked and the dirt climbed up surface. The process is similar to liquefaction: seismic waves usually turn solid layers into a fluid liquid, often with catastrophic results for buildings and people on the surface Of the earth. Mr. Barnhart is skeptical of media reports that that the same liquid was methane hydrates. Free methane carbon dioxide, water – whatever, but methane hydrates occur much deeper, the specialist emphasizes. Earthquake epicenter located too far from the coastline to cause large-scale changes, and the earthquake itself was not the same type to lead to a major uplift. Earthquake in 1960 in Chile, a magnitude of 9.5 lifted entire villages a few meters up, but it was an earthquake with a vertical displacement along the edges lithospheric plates, while in Pakistan the layers have only shifted horizontally.
