今天是美麗化學四嗎?不!是美麗地理1!大家知道有什麼因素會影響地震後的傷亡人數和經濟損失嗎?我們可以分為兩類
Physical factor:
1. High magnitude. When there’s higher magnitudes, there’ll be more energy released from focus, leading to stronger vibration of the rock of the crust. Therefore, more building couldn’t withstand the vibration and collapse, and more lives are buried by the collapsed building.

2.shallow focus. When the focus of earthquake is shallower (less than 70 km). There’ll be less energy loss when seismic waves travel in all direction and reach the epic centre, so there will be stronger vibration . Therefore, more building couldn’t withstand the vibration and collapse, and more lives are buried by the collapsed building
3. Time of occurrence. When the time of the hazard occur is in dawn or late night. The awareness of people will be lower and lead to less effective evacuation.
cultural factors:
1. Low literal rate (lower than 98%). Low literal rate will lead to lower awareness and lead to less effective evacuation.
2. Long history of development. If the place has long history of development, more building are in simple structure so fewer building have earthquake proof design . Therefore, more building couldn’t withstand the vibration and collapse, and more lives are buried by the collapsed building
3. Low level of economic development. When a country has lower GDP, it shows that it has lower level of economic development, so it has less capital to improve budding structure, so there will be less earthquake proof design building.(Haha 破壞了兼職芒果的系列
