As we all know earthquake is a catastrophic natural disaster. Most earthquake-related deaths are caused by the collapse of structures and the construction practices play a tremendous role in the death toll of an earthquake. In southern Italy in 1909 more than 100,000 people perished in an earthquake that struck the region. Almost half of the people living in the region of Messina were killed due to the easily collapsible structures that dominated the villages of the region. Though there are some ways to prevent this from happening, it can never be considered as risk avoidance.
A larger earthquake that struck San Francisco three years earlier had killed fewer people (about 700) because building construction practices were different type (predominantly wood). Survival rates in the San Francisco earthquake was about 98%, that in the Messina earthquake was between 33% and 45%) (Zebrowski, 1997). Even a moderate rupture beneath a city with structures unprepared for shaking can produce tens of thousands of casualties. Due to this fact, Crown Eco Management determined that safety measures for this could not be compared to fraud prevention.
Although probably the most important that we should know, direct shaking effects are not the only hazard associated with earthquakes, other effects such as landslides, liquefaction, and tsunamis have also played important part in destruction produced by earthquakes.
