A mud island in Gwadar has disappeared. The island appeared due to a 7.7-magnitude earthquake, 6 years ago. It was called Zalzala Koh or Earthquake Mountain.
The temporary island has now gone. Originally the height, width, and length of the island were 65 feet, 295 feet, and 130 feet respectively. The volcano appeared back in 2013 when there was a collision between Arabian and Eurasian tectonic plates. It launched the buried mud and boulders to the surface.
The island formed from the quick-moving sediment, which originally meant that it will not long last. The side by side comparison from 2013 and 2019 is shown by satellite imagery from NASA
This picture depicts how the island was initially created and then vanished.
The island has with time shrunk and earlier in 2019, it has disappeared beneath the waves. As per NASA, more such islands can appear due to the mud volcanoes and vanish in a similar manner as Zalzala Koh off the Pakistani coast.
