Meteor Airburst off the coast of Japan

2025, August 19. Japan. Large Airburst. Time: 14:08:48UT, 23:08 LT. Coordinates: (131.8E, 30.9N). Altitude: 27.5 km. Velocity: 19.624 km/s. Energy: e = 65.8e10 or -e = Impact energy of 1.6 or 1,600,000 kg/TNT. Approximatly 70km NE of Tanegashima Island and 80 km from Japans coastal mainland. Many people in Kagoshima and Miyazaki prefectures posted on social media that they had seen a ball of light in the sky. The flash was so powerful it lit up Kagoshima City completely, 140 km away, for a few seconds. It was also filmed clearly from Kansi airport 500km to the NE. Eight minutes later, a notable atmospheric pressure wave measuring 12.5 pascals was recorded southeast of Sakurajima, 120km from the event. Seismic instruments also detected ground vibrations. Staff at the local weather office on the opposite side of Kagoshima Bay reported hearing a loud “boom” after opening a window. This is the 23rd airburst recorded this year. A Marine Animal Disturbance Alert should be noted for the coastal regions of SE and Central Japan and surrounding islands.
