Well it depends how close the places are to the edges of tectonic plates. Also the damage caused from the Earthquakes has to do with how sturdy the buildings are and whether they were built to withhold such strong forces.
In the analysis of the molecular formula of organic molecules, the degree of unsaturation (also known as the index of hydrogen deficiency (IHD), double bond equivalents, or unsaturation index) is a calculation that determines the total number of rings and π bonds
In order to find the number of neutrons in the atom,
you need to calculate the difference between the top and bottom numbers
which means 272 - 111 = 161
Hope this helps
