広島に落とされた原爆
   

Super-Hot Fires
The heat ray generated simultaneously with the explosion of the atomic bomb caused houses, etc., in the hypocenter vicinity to ignite spontaneously. Kitchen flames in houses collapsed by the blast spread and began to consume houses here and there. Such fires rapidly enveloped Hiroshima City in a day-long conflagration that peaked from around 10:00 a.m. to 2:00 or 3:00 p.m. Areas within a two-kilometer radius of the hypocenter were reduced to rubble. Many people trapped under houses collapsed by the blaze were burned alive.
