Translations from Japanese as numbered below. *1 Volcano name: Sakurajima volcano. *2 Information title. *3 Time of issue and source: Issued at 05:00 JST on November 7, 2014, by Seismology and Volcanology Department of JMA. *4 Summary: Forecasts of areal extents of ash fall and lapilli fall for possible eruptions at three-hour intervals between 06:00 and 24:00 JST on November 7 are provided by the maps below. The forecast of areal extent of ash fall between 09:00 and 12:00 JST is forecasted to southern direction and that between 21:00 and 2400 JST is forecasted to north-west direction. Forecast areas of ash fall and lapilli fall are based on an eruption producing a 3000 m vertical plume above the crater. People in areas where lapilli fall is forecast should stay indoors or take refuge under a solid roof. *5 Legend: Forecast areal extents of ash fall and lapilli fall. “Gray filled area”: Ash fall. “Red filled area”: Lapilli fall (≥1 cm size). *6 Annotation of time of eruption: 15:00 – 18:00 JST on November 7. *7 Direction and distance from the crater to maximum extent of ash fall area. Name of localities affected is provided in parentheses: Direction and distance are south-east and 20 km, respectively (direction of Tarumizu city and Kanoya city). *8 Map showing forecast areal extent of ash fall. *9 Distance from the crater to maximum extent of area of lapilli fall: 3 km. *10 Map showing forecast areal extent of lapilli fall.
