In 2013, in Pakistan, there was a strong earthquake, which claimed the lives of hundreds of people and destroyed thousands of homes. However, unlike other earthquakes, this disaster left behind not only destruction — after it on the coastline of the country has formed quite a large island composed entirely of dirt. It could easily be observed from satellites for more than five years, but by 2019 it started to disappear. Why it was formed, and why it so quickly faded from the face of the Earth?
The reason for the formation of Islands in the Arabian sea was a strong earthquake of magnitude of 7.7. After it, in the country there were four more of the quake, which destroyed more than 20,000 homes. The number of deaths during a series of earthquakes has reached 825 people and injured more than 700 local residents.
As the Islands are formed out of the mud?
As you know, earthquakes occur due to movement of the so-called tectonic plates — the underground blocks of great size, which are constantly in motion and are inherently the surface of the Earth. Aftershocks in Pakistan was caused by the collision of the Arabian and Eurasian tectonic plates, which between them formed the clay deposits under pressure began to escape to the surface.

The largest mud volcano
Education, under great pressure, escapes the dirt, gases and a mixture of water and oil are called mud volcanoes. Usually, their height does not exceed two metres, but escaping from under the Arabian sea, the dirt was so much that on the water surface formed a island 20 feet high with a width of up to 180 meters. Mud volcanoes and formed by them the Islands can be found all over the world, but this one was so huge that it was visible even from space.
The island was Zalzala Koh with companion
However, life on this island, which later got the name was Zalzal Koch, was short-lived. As it consisted of semi-liquid mud, its surface began to blur water for a couple of months. On the satellite pictures below, you can see how even in 2016, the outlines of the island were at least a little species, and by 2019, he almost lost sight of.
The disappearance of the island was Zalzala Koch
With all this, this island can not be considered completely disappeared. Mud volcanoes sometimes are activated by two to three times, and after a few years the island may appear on satellite images.
