Jiji Press TOKYO (Jiji Press) — The Japan Meteorological Agency expanded on Saturday its warning area from 3 kilometers to 4 kilometers from the crater of Shinmoedake, a volcano in southwestern Japan, after explosive eruptions.
The agency said large ash deposits reached as far as 1.8 kilometers from the crater after an explosive eruption in the small hours of Saturday.
The volcanic alert for Shinmoedake was kept at Level 3, which restricts entry to the volcano, part of the Kirishima mountain range straddling Miyazaki and Kagoshima prefectures.
The agency warned of the possible arrival of large ash deposits within 4 kilometers of the crater and pyroclastic flows within 2 kilometers.
The explosive eruption occurred at 1:54 a.m., with volcanic smoke reaching as high as 4,500 meters from the crater, the agency said.
