Vast amounts of soil flowed into the sea off the coast of areas stretching from the Tohoku to Tokai regions, following record rainfall from Typhoon No. 19, a satellite image of Japan taken Oct. 13 shows.

The photo, provided by the Japan Aerospace Exploration Agency (JAXA), shows surface runoff from the mouths of rivers carrying soil 10 to 20 kilometers out to sea.

Shikisai, JAXA’s climate change observation satellite, captured the image at around 10:50 a.m. on Oct. 13, a day after Typhoon No. 19 made landfall in Japan.

“The dirt spreading so far out into the sea suggests that the flow of the river current was extremely fast at that time,” said Yuuji Sakuno, an associate professor of satellite oceanography at Hiroshima University, who analyzed the satellite data.
