Effects of temperature increase on earthquake frequency

In the last few decades, the earthquake frequency has been found increasing throughout the world. Similarly, the temperature has also been found rising significantly since the onset of 20th century. Now many people are asking that can temperature be the cause of enhancing seismic activity? The answer is “Yes”. The research on this issue has been conducted in the Department of Earth and Environmental Sciences of Bahria University, Islamabad, Pakistan by Muhammmad Usman (BS Geophysics 7th semester student) in the supervision of Muhammad Zafar, Tehseenullah Khan and Mamoru Morata (Naruto University of Education, Tokushima, Japan). This study has proved that the growing temperature is causing the glaciers of Northern Pakistan to melt, releasing pressures and the Earth may possibly rebounds, in response to this decreased load, to cause earthquakes . The trends of earthquake frequency and temperature increase are strikingly similar. The study further indicated that the magnitude that correlates with temperature rise falls in the range of 3-4.9 and the depth affected by this process is no more than 160km . The seasonal variations show that the winters are more earthquake prone than the summers .
