At 5:46 a.m. on January 17, 1995, the Southern Hyogo Prefectural Earthquake (aka: the Kobe Earthquake), the first major quake to directly hit a Japanese urban area, inflicted unprecedented heavy damage in the region on such cities as Kobe, Awaji, Ashiya and Nishinomiya and their surrounding areas. The powerful jolt, which lasted barely 20 seconds, took 4,571 lives in Kobe city alone. Especially in areas where old wooden homes were concentrated, buildings simply collapsed and large-scale fires broke out, effectively reducing the elegant harbor city to mere piles of debris and rubble and depriving many people of the very basis of their livelihood.
