The pumice stone produced by the volcanic eruption has been discovered in various parts of Japan. According to the prediction of the current direction, the pumice stone may float to the coast of eastern Taiwan, China and the waters near the Philippines.
According to the latest satellite observation data released by Japanese marine R&D institutions on the 26th, pumice stones have been discovered in the Izu Islands and Okinawa Prefecture. According to the ocean currents, pumice stones face south along the direction of the Ryukyu Islands and may float to Taiwan Island in China and the waters near Luzon Island in the Philippines in the future.
A large number of volcanic pumice stones cover the sea surface
Affected in many places in Japan
Volcanic pumice stone refers to a mineral formed by cooling the magma after a volcanic eruption. The main component is silica, which has a soft texture, a small specific gravity, and can float on the water surface. According to Japanese media reports, in August this year, the largest eruption in more than 70 years of undersea volcano in Ogasawara Archipelago, and the resulting volcanic pumice stones floated on the sea.
The 17 cities and villages in Okinawa Prefecture, Japan, the 12 cities and villages in Kagoshima Prefecture, as well as Tokyo, Kanagawa Prefecture, Chiba Prefecture and other places have all been affected by pumice stones.
A large number of pumice stones are piled up on the coast, which looks like a gravel beach from a distance, but in fact, there is sea water under these pumice stones. Some local people tried to swim in such water, but they were almost unable to move forward.
Japanese people:
The thickness of the pumice stone in the water is about 30 cm, and it cannot be swim at all. It is too thick and it feels too dangerous.
The government allocates 7 billion yen
to treat marine garbage such as pumice
Due to concerns that pumice stone will have an impact on the local tourism industry and landscape, various parts of Japan have called on the central government to take measures to clean up. To this end, the Japanese government decided to invest 7 billion yen in this year's amendment budget to dispose of marine garbage such as pumice. In addition to the undersea volcanoes in the Ogasawara Islands, in the past year, volcanic eruptions have occurred in many places in Japan, including Kumamoto Prefecture and Kagoshima Prefecture.
