Abstract

A massive tremor stuck Baluchistan Pakistan on September 24, 2013 with a magnitude of 7.7 recorded on Richter scale. The epicenter was Awaran Baluchistan which directly affected about 300,000 people leaving about 386 causalities. The impact of this earthquake was so much large that it created a new landmass which was named as Zalzala Koh later. It was the result of strike slip faulting at a depth of 15km. The new born island was full of rich minerals, gases and dead sea animals. This island was 60 feet high, 100 feet wide and 250 feet long. The classification results of Landsat 8 show that the island completely disappeared in 2019 after 6 six years of its birth. First the volume of this island decreases due to reduced pressure of internal gases and secondly, the high-pressure water waves vanished it completely. Satellite imagery proved efficient for spatio-temporal monitoring of various landuse classes.

Highlights

Seismic tremor or earthquakes are natural hazards which devastate the natural beauty and ecological balance of a region badly [1]

Summary

Introduction

Seismic tremor or earthquakes are natural hazards which devastate the natural beauty and ecological balance of a region badly [1]. They found that the Arabian plate was subducted beneath the Eurasian plate The earthquake which happened in 1945 was off the Makran coast that created an island which vanished later Such earthquakes are powerful enough that a new coast line can be generated as a result e.g., an earthquake of magnitude 8.8 hit Chile in 2010 and changed the shape of coastline completely [22] and even shorten the length of day. At the time of happening of an earthquake, there exists a very large pressure of gases which reduced with time that caused to contract and square back the swelled land mass Another reason of vanishing the Zalzala island was due to the slipping of raw material underneath it’s base.
