Earthquake in Pakistan Essay

Earthquake activity in Pakistan is mainly concentrated in the north and western sections of the country, along the boundary of the Indian family and the Iranian and Afghan micro-plates. The Chaman Fault runs along Pakistans western frontier with Afghanistan from Kalat, in the northern Makran range, past Quetta and then on to Kabul, Afghanistan. A fault as well as runs along the Makran coast and is believed to be of the same nature as the West Coast fault along the coast of Maharashtra, India. An active subduction zone exists off the Makran coast. The spectacular 1945 earthquake was centred in this region.This zone forms the boundary between the Arabian and the Iranian micro-plate, where the former subducts or dives beneath the latter. Thrust zones run along the Kirthar, Sulaiman and Salt ranges. at that place are four faults in and around Karachi and other parts of deltaic Indus, and Makran coast. The first is the Allah Bund fault that passes through Shahbundar, Jah, Pakistan Ste el Mills, and runs through eastern parts of the city and ends approximate Cape Monz. This fault, in fact, has caused extensive damage in the past many centuries in the deltaic areas.The destruction of Bhanbhor in the 13th century and damage to Shahbundar in 1896 were caused by this fault. The other one emanates from the Rann of Kutchh. The third one is the Pubb fault which ends into Arabian sea near Makran coast and the last one is located in the lower Dadu rule near Surajani and falls in the vicinity of Karachi. Tsunamis or tidal waves have also affected the coast of Pakistan. The worst case was in 1945 when an earthquake of order of magnitude 7. 9 struck the Makran coast, waves as high as 12 meters were reported.
