Abstract

In this paper, the seismic activity of glacial area (northern Pakistan) is compared with the planar area (upper Punjab) by with reference to the focus range of earthquakes. The seismic data is of duration 1961-2004 and is provided by Pakistan Meteorological Department (PMD). In the latest studies conducted over northern Pakistan, a positive correlation between temperature increase and earthquake frequency has been found. As rising temperature is causing the glaciers of northern Pakistan to melt and the earth may possibly rebounding in response to this decreased load, to cause earthquakes. The focus range, resulting from expected rebound in northern Pakistan, is 0-160 km. Due to this expected loss in mass of glaciers, the discharge of various water tributaries should also increase with time that pass through the planar areas of upper Punjab. Due to possibly increasing discharge, the potential of rivers for erosion, transportation and deposition of sediments may also increase. So, it means that the balance across faults is being disturbed due to this expected relocation of sediments. As a result of this balance shift, the faults are responding in form of earthquakes in the upper Punjab. The focus range of planar area (upper Punjab) that correlates with the temperature increase in glaciated area (northern Pakistan) is 0-40 km.
