大地震後，往往伴隨火災發生，且由各項歷史地震資料顯示，震後火災在震後一小時內發生率達最高峰，面對突如其來的多起火災，消防機關熱必無法完全掌握，如此所造成的損失也就比平時單起火災高出許多。 本研究主要目的則在藉評估消防機關搶救震後火災能力，得知震後火災搶救程度，以做為補充裝備、晉用人員之參考依據。為此，乃以九二一災區南投縣內死亡人數最多之埔里鎮為例，分二部分進行，一方面做災害情境想定，一方面由迴歸方式求出火災與搶救能力之關係式，最後整合皆析即可粗略估得震後火災搶救程度。

According to every historical earthquake materials, there are many fires occurred after a heavy earthquake, especially in period of one hour after the quake. To face such more after-quake fires, local fire bureau certainly be unable to handle all of those. So, the loss caused by after-quake fires are much higher than that caused by usual fires. The main objective of the study is to know the degree of after-quake fires rescues by evaluating fire extinguishment ability of local fire bureau. By this, we can decide how much hardware and how many staff should we increase. For this reason, we take Puli town, the town of most death in disaster area, Nantou County, during 921 earthquakes, for instance and proceed in two ways. One way is to image calamity situation. The other way is to find the relation function between fire scope and extinguishment ability by regression. Finally, we can combine the two parts to analyse to estimate the extinguishment degree of after-quake fires roughly.
