A REVIEW OF EARTHQUAKE DISASTER PREVENTIVE MEASURES FOR LIFELINES
|
´˜^i‰pjF
The Miyagiken-oki Earthquake of 1978 with 7.4 of magnitude brought many disasters to one of the most modernized cities of Sendai and its adjacent area. The disaster is supposed as one of the biggest earthquake disasters since the Kanto Earthquake of 1923 with 7.9 of magnitude. The El Asnam, Algeria Earthquake of 1980 with 7.3 of magnitude brought damage in lifelines. Consequently the event showed three types of recoveries of the function I.e., I)INDISPENSABLE in transportations, ii)ALTERNATIVE in water and gas supply, iii)SUSPENDABLE in telecommunication, power supply and sewage disposal. The southern Italy Earthquake of 1980 with 6.5 to 6.9 of magnitude affected suspension of functions to lifelines in relatively wide areas, for example, Napoli located about 100 km from the epicenter suffered the suspension. Concludingly, three of these earthquake disasters with individual characteristics tell us lessons for earthquake disaster preventive measures.
