After the Wenchuan 5.12 earthquake many people wondered why so many people were killed or injured. What isthe best way to prevent tragedy from earthquakes?
Preventing Earthquake Damage
The devastating 8-magnitude Wenchuan earthquake cost at least 70,000 lives, making it the deadliest earthquake to hit China since the 1976 Tangshan earthquake. There has been a heated debate concerning how to prevent earthquake damage. In my opinion, improving building quality and constructing earthquake-resistant buildings should be made a top priority.
To begin with, improving building quality will greatly reduce the number of buildings collapsing in an earthquake, Building vulnerability is closely linked to the casualty rate in a catastrophic earthquake. The central government estimates that over 7,000 inadequately engineered schoolrooms collapsed in the earthquake. Chinese netizens have since invented a catchphrase"tofu-dreg schoolhouses to mock both the quality and the quantity of these inferior constructions that killed so many school children, Substandard building materials were used in some constructions, constituting a great potential danger to people's lives. Therefore, improving building quality should be put on top of the government's agenda so as to prevent much of the disastrous effects of earthquakes.
Secondly, earthquake-resistant buildings can effectively withstand earthquakes. In the Wenchuan earthquake, many people were killed due to the low standard of earthquake-resistant buildings. China has adopted new legislation to enforce proper quake-resistant structures. Hence adopting an advanced quake-proof technique to build high-standard quake-resistant buildings is indispensable to tragedy prevention from earthquakes.
In conclusion, improving the design and the quality of buildings is the best way to prevent the tragic effects from earthquakes.
1.We can never prevent an earthquake. It is a force of nature and the power released is incredibly large．
2.However, we can take precautions to reduce loss of life and property damage.
3.One efficient way to reduce the damage is to design buildings that conform to the seismic zoning of the area.
4.Remember that earthquakes do not usually kill. Buildings,tidal waves (tsunami), falling objects,stupidity and ignorance do.
5.through historical and past data, seismic agencies around the world are able to compile statistical estimates and probabilities of an earthquake of certain magnitude occurring within a period of time over a certain fault or area.
