MIRPUR (AJK), (Parliament Times): Recent frequent earthquakes in this Mangla lake city of Mirpur, Azad Jammu Kashmir and certain of the  areas in its outskirts, particularly  in the month of September this year and in the same month last year,  alerted the geologists and seismic experts  over almost identical intensity of the catastrophe that jolted the city, holding the country’s second largest reservoir – the Mangla dam in its lap. An immediate study conducted by this Correspondent on Saturday unveiled that experts seemed compelled on an identical and unanimous viewpoint about conducting  an integrated and  comprehensive survey study by an independent and credible survey group of  good world professional repute of national or international standards. According to preliminary probe conducted by  a seasoned dams and power generation expert Engr. Muhammad Iqbal  Ratayal, the recent  series of earthquakes experienced in Mirpur City of AJK and some of  its adjoining areas particularly during  past few days  have compelled the experts to raise besides alerting the local population of the impending devastating effects of the calamity with prime focus over unearthing the true causes of the frequent catastrophe recalling the deadly earthquake of Sept, 24 last year that had claimed at least 40 human lives besides leaving  hundreds of others injured beside rendering thousands of the people homeless damaging the billions worth private property  – residential and commercial  buildings besides the infrastructure  in different form. Elaborating his immediate  investigative study,  Engr. Rattayal, Retired Secretary to AJK Government for Electricity and Power Development, told this Correspondent here on Saturday that because of the series of recent frequent outburst  of the earthquakes in Mirpur lies in moderate seismic intensity Zone. “The main Fault system was Jhelum Thrust Fault near the locations (epicenters), the nearest fault close to the epicenter was Dil Jaba Thrust fault and the Rawat Fault was lying parallel”, he observed. Moreover, Engr. Iqbal Rattayal continued while   commenting  that the catastrophe also lied well with in the Geographical Coordinates of Mangla Dam (33.14N—73.04E) as large new reservoirs can trigger earthquakes, due to increased water pore pressure decreased the strength of the rock under the reservoir. “The correlation between the maximum water level attained by Mangla Dam Reservoir and the Seismic indicators of recent series of Earthquakes on the respective date Shown in below table also invites an immediate attention of all stake holders and experts”, he observed quoting   immediate analysis of  European-Mediterranean Seismological Center (EMSC).

Devising the following table comprising his study, Engr. Ratayal strongly recommended that earthquake hazards need to be on the table for an onward comprehensive study, investigations and evaluation by independent experts  of global report  primarily to address the local general public concern. Following table containing immediate study  by the above experts is food for thought for all concerned stake holders:-
