Q7. Explain why some temblors can cause a greater extent of modify than other ones even though they are weaker. (Depth of focus, location of epicentre, compactness of settlement, type of building, seism forecast, etc) The erect of an earthquake is not the unaccompanied portion that hazards the extent of pervert done to an area. For instance, the earthquake in Anchorage, Alaska in 1964 had an earthquake of assure of magnitude 9.2 on the Richter exfoliation; its oddment toll was only 115. On the other hand, the Great Sichuan earthquake of magnitude 8.5 on the Richter scale had a death toll of at to the lowest degree 69,000. This showed that on that point are several other factors that affect the extent of abuse, mainly, surmount from epicenter, state closeness, and type of soil and the train of preparedness. Firstly, the distance from the epicenter is one of the factors that affect the extent of damage done to an area. Places nearby to the epicenter of an eart hquake generally welcome the strongest shock waves, olibanum they are most likely to fuck off the most damage.
