According to the collection

analysis and evaluation of 28 prison seismic disasters in China

we divide them into 3 classes:serious

moderate and light. Looking through the changes of these seismic disasters in time sequence

we find that they are lessening with the time. The prisons are special buildings for prisoners

therefore

emergency measure after earthquake is very important in the whole seismic contingency work. There are lots of special countermeasures against it.In this paper

we also discuss many other problems during seismic disaster. For example

transferring and managing the prisoners

treating the injured prisoners and educating them

paying attention to hitting and frightening the bad prisoners

encouraging and accepting the prisoners’participating in relieving the people in disaster and their donating

and so on.Lastly

we put forward several aspects of establishing counter measures about prisonal seismic emergency.
