In September, 1961, and September, 1962, large scale explosion experiments with 150 kg to 3 t of explosive were carried out in Hokkaido and near Lake Biwa, and data were obtained on blast pressure, damage on houses, attenuation of shock wave by banks etc. which are supplemented by high speed photographs taken by two Fastax cameras at a rate of approximately 4, 000 fps.
Together with detailed explanation of how the high speed photographs were taken, information concerning the following items are given.
(1) Generation and growth of fire ball.
(2) Shock wave perceived over the background or by Wilson cloud chamber effect.
(3) Transformation of flame into smoke.
(4) Disintegration of smoke.
