In September 2013, a 7.7 magnitude earthquake hit Pakistan, the death toll stopped at 825 people and there were many injured. But there was one more thing that came out from this. A tiny baby island sprang up in a shallow bay near the port city of Gwadar. The island was named Zalazala Koh which means ‘Earthquake Mountain’ in Urdu. (Genius, I know.) The island was oval-shaped and 20 meters high, 90 meters wide and 40 meters long. It was formed due to a mud volcano that erupts overlying sediments. The volcano was the result of the shifting of plate tectonics. The Arabian plate is sinking beneath the Eurasian plate by a few centimetres per year. The process pushes soft sediments onto the edge of the Eurasian plate and becomes a key ingredient for mud volcanoes. Geologists said that this island would not last long when faced with high tides and waves. They would wash away the mud and chip away at the mud volcano. Those geologists were right. The island, six years later, has now completely disappeared. Satellite images of the area over the years showed mud discolouring the surrounding areas near the island. This was because of the erosion that was taking place. By the end of 2016, there was not much of the island left above the water.
