| They were assembled from meagre rags of clothing left on three boys, aged twelve to fifteen, who happened to be a thousand yards from the bomb's hypocenter above Hiroshima. |
| The degree of damage depends upon the distance from the center of the bomb blast, which is called the hypocenter or ground zero. |
| Located only 500 meters from the hypocenter of the blast, the three-story, reinforced concrete building was heavily damaged. |
| If it is identified a significant event it is registered, they can identify the hypocenter, the magnitude, the focal mechanism and the parameters of the source. |
| The hypocenter of the earthquake was located about 130km off the Pacific coast of Tohoku region, from Iwate to Ibaraki Prefectures, the JMA said. |
| These data will permit more accurate earthquake hypocenter estimates, as well as better estimates of earthquake magnitude and other characteristics indicative of tsunamigenic potential. |
