Detailed explanation-1: -Most of the hazards to people come from man-made structures themselves and the shaking they receive from the earthquake. The real dangers to people are being crushed in a collapsing building, drowning in a flood caused by a broken dam or levee, getting buried under a landslide, or being burned in a fire.

Detailed explanation-2: -According to the United States Geological Survey (USGS), there are three main factors that determine your seismic risk: the level of the seismic hazard, exposure to the hazard and how vulnerable that population and property is to the hazard.

Detailed explanation-3: -Damaged buildings, damaged power lines, and leaking gas and water lines are just a few of the hazards you might face after an earthquake.

Detailed explanation-4: -Seismic risk is the probability that a subject site will be adversely affected by any seismic hazard, such as an earthquake. Seismic risk tends to increase in areas that are more earthquake-prone and vulnerable to damage. And vulnerability refers to the potential impact on people, as well as properties.
