Iftikhar A Raja, THE BALOCHISTAN EARTHQUAKE 2013: EMERGENCE OF A NEW ISLAND IN THE ARABIAN SEA(2017)SDRP Journal of Earth Sciences & Environmental Studies 2(1)
A massive earthquake of 7.7 magnitude struck south-central Pakistan on September 24, 2013. The epicenter of the earthquake was 63 km north-north-east (NNE) of Awaran in Baluchistan. The earthquake caused the death of 386 people, leaving thousands homeless. The earthquake also affected different cities in Iran, India and Afghanistan. The fundamental cause of the earthquake was displacement along oblique-strike-slip fault at a depth of only 15 km (9.3 miles). The quake has created an island in the Arabian Sea which is an unusual in case of strike-slip faulting and it raises the question of the nature and original mechanism of the earthquake. The formation of the island indicates that there is a significant push of the northward moving Indo-Pakistani plate along with oblique-strike-slip faulting which was the original motion of the earthquake. These facts were discussed and explained in this paper.
