The seismic data is of duration 1961-2004 and is provided by Pakistan Meteorological Department (PMD). Both glacial and planar areas show remarkably similar behavior in earthquake frequency. In the latest studies conducted over northern Pakistan, it is thought that the temperature can be the cause of increasing earthquake frequency. As rising temperature is causing the glaciers of northern Pakistan to melt and the Earth is possibly rebounding, in response to this decreased load, to cause earthquakes. Due to this expected loss in mass of glaciers the discharge of various water tributaries, which pass through upper Punjab, should also escalate with time. As a result of this possibly growing discharge, the potential of rivers for erosion, transportation and deposition of sediments may also increase. So, it means that the balance of load 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 that have magnitude 3-4.9.
