地震危害
1.Shaking and ground rupture
Shaking and ground rupture are the main effects created by earthquakes,principally resulting in more or less severe damage to buildings and other rigid structures
2.Landslides and avalanches
Earthquakes,along with severe storms,volcanic activity,coastal wave attack,and wildfires,can produce slope instability leading to landslides,a major geological hazard.Landslide danger may persist while emergency personnel are attempting rescue
3.Fires
Earthquakes can cause fires by damaging electrical power or gas lines.In the event of water mains rupturing and a loss of pressure,it may also become difficult to stop the spread of a fire once it has started
4.Tsunami
Large waves produced by an earthquake or a submarine landslide can overrun nearby coastal areas in a matter of minutes.Tsunamis can also travel thousands of kilometers across open ocean and wreak destruction on far shores hours after the earthquake that generated them
地震预防
Today,there are ways to protect and prepare possible sites of earthquakes from severe damage,through the following processes:earthquake engineering,earthquake preparedness,household seismic safety,seismic retrofit (including special fasteners,materials,and techniques),seismic hazard,mitigation of seismic motion,and earthquake prediction.Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity,ground motion,or soil failure due to earthquakes.With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers,the need of seismic retrofitting is well acknowledged
