近年来,地中海-喜马拉雅地震带和环太平洋地震带的地震活动较为活跃。先后发生了不少强烈地震。如今年5月21日阿尔及利亚发生6.7级地震,造成许多房屋倒塌、城镇被夷为一片废墟、死亡2250人、受伤1万多人的惨剧;5月26日在日本富城县发生7级地震,房屋未倒一间,没有1人死亡,只有104人受伤,给该地的交通和市民生活带来短暂影响。人们不禁要问,同样发生大地震,地震灾害的轻重却大不相同?面对这种现象,有人感到困惑,有人积极探讨其缘由。不过,催人猛醒的是,从中认清了地震真正凶残的杀手,确实是房屋的倒塌。一般说,地震烈度的高低,与震级的大小、震源的深浅、地质构造的复杂程度、震中在陆地还是在海域等
In recent years, the seismic activity of the Mediterranean-Himalayas and the Pacific Rim has been relatively active. There have been many strong earthquakes. On May 21 this year, a magnitude 6.7 earthquake struck Algeria, resulting in the collapse of many houses, the ruins of cities and towns, the death toll of 2,250 people and the injuries of over 10,000 people. On May 26, a magnitude 7 earthquake struck Fucheng County in Japan, No one was left in the house, no one was dead and only 104 were wounded, causing a transient impact on the traffic and public life in the area. People can not help but ask: Are there any big differences in the magnitude and magnitude of the same earthquake and earthquake? Some people are confused by this phenomenon and some actively discuss its causes. However, what urges people to wake up is that they realized that the real cruel killer of the earthquake really was the collapse of the house. In general, the magnitude of the earthquake intensity, the magnitude of the magnitude, the depth of the source, the complexity of the geological structure, the epicenter of the epicenter or the sea
