If earthquake happened,firstly,don't panic and calm down.Secondly,find some safe place to stay and don't run in such a hurry.If in the room,one should hide himself/herself under something hard,such as desk,talbe or even bed and keep away from shelf and cupboard,and never take a lift to go downstairs.If in the open air,find an open place and never get close to cars or waterside.Thirdly,because when earthquake happen,there are also lots of other troubles to take place,for example fire.So we should help each other when we meet trouble.At last,no matter how strong the earthquake is,if only we have the belief to defeat it and never give up,we must be able to overcome any difficulties.
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.
My name is Susanna. In our city, there was an earthquake at 8:32 yesterday evening.
At that time, I was taking a shower in the bathroom. My motherwas cleaning up the kitchen and my father was watching TV in the livingroom. My elder sister Alice was working on her com*r in her room. We were very scared.
Luckily, the earthquake was not heavy and it didn’t last long. And we were all safe.
