TOKYO, Oct 26 (NNN-NHK) – Japan Meteorological Agency (JMA), warned of another possible major volcanic eruption of Mt Aso, in south-western Japan, where an increase in volcanic earthquakes was observed, local media reported today.
The JMA said yesterday, the magnitude of the volcanic tremor in the No.1 Nakadake crater of the volcanic mountain, rose sharply from late Sunday to early Monday, while confirming changes obviously caused by expansion in the shallow part of the crater.
Following the eruption of the 1,506-metre crater before noon tomorrow, the JMA raised the volcanic alert level to 3 on a scale of 5 and prohibited access to areas within two km of the crater.
The JMA said, the volcanic ash spewed over one km from the crater, and a pyroclastic flow was observed within 1.3 km west of the crater for the first time since Oct, 2016.
No deaths or injuries were reported last week. At the time of the eruption, 16 climbers on the mountain made the descent without injury.– NNN-NHK
