JAKARTA: Indonesian authorities on Monday (Jun 29) raised the alert level after Mount Raung in East Java erupted, causing ash to land in surrounding villages.
The eruption at Mount Raung on Sunday evening was heard 20 kilometres away, and ash fall was seen in villages about 10 kilometres away from the summit. Aircraft pilots also reported seeing large amounts of ash at a height of 3,500 metres.
Authorities cordoned off a two-kilometre radius around the volcano, and raised the alert level to “Siaga”, the second highest level.
The Head of Prevention and Disaster Preparedness at the local Natural Disaster Mitigation Agency added the eruption could be seen from a lookout post in Banyuwangi, East Java.
Volcanologists have recorded an increase in volcanic activity and tremors on the 3,332-metre high Mount Raung since Jun 24.
Apart from Mount Raung, other volcanoes for which Indonesian authorities have raised the second highest alert level are Mount Karangetang, as well as Mount Soputan and Mount Lokon in Sulawesi.
