The bearing capacity of the soil is a significant topic in geotechnical engineering, especially in foundation engineering, as the stability of any foundation depends on it. A structure with a very sound design may collapse standing on poor soil with low bearing capacity. As the depth of the water table increases, the ultimate bearing capacity of soil increases. The effect of an increase in depth on safe bearing capacity is predominant due to an increase in surcharge weight. The higher the water table, the lesser is as far as possible and strength of the soil. In this research, soil test reports of different locations of Dhaka city were collected, and the bearing capacity of the soil was calculated by Terzaghi's method based on a fixed foundation depth with a variation of water table depth. Bearing capacity was compared with the depth of the water table in graphical format and it was seen that bearing capacity of soil increases with the increase of water table depth.

Bangladesh is a South Asian country with a dense population situated in a very vulnerable position of earthquake faults where sudden earthquakes can cause a great loss of lives and properties. This paper deals with the magnitude and focal depth of earthquakes that have been felt from 2015 to 2019 having Richter magnitude more than 3. Maximum earthquakes with a magnitude of 3.0 to 4.9 have occurred at the northern side of Bangladesh whereas at the eastern side the values are between 4.0 to 5.9. It was seen that considerable earthquakes occurred in 2019 at the northern side of Bangladesh that indicates a major earthquake may happen in this area from the stored energy and can cause a devastating effect. It has been observed that Earthquake with more than 3 Richter magnitudes has happened in all five years in February, April, August, and September where January and December have comparatively fewer earthquake records. Focal depths have been found to be higher in 2016 related to other years. A correlation equation has been developed between magnitude and focal depth.
