After three days of study of seal colonies in the Somme Bay, volcanic activity reasserts itself.
Several airports are closed because of ash from the volcanic eruption of Raung.
At least 5 airports in Indonesia are closed because of ash emitted into the atmosphere by the volcano for a second day in western Java. It affects air traffic and flights between Bali and Australia were canceled, affecting many tourists.
The ministry said that the airports will reopen according to the evolution of the volcano which is 120 km from Denpasar airport. The other four airports are:
– The Lombok International Airport,
– Airport Selaparang in Lombok,
– Blimbingsari Airport
– Notohadinegoro Airport Jember in East Java.
The Head of Geological Agency of the Ministry of Energy and Mineral Resources (DEMR) Mr Surono calls people who live around the foot of Mount Raung, East Java, not to panic and not to believe that the mountain will break out in the near future.
Surono explained that the eruption of Raung is Strombolian type. This means that an eruption that spewed incandescent material will be like sparks of fireworks, seen in the night.
He continued, saying that the type of eruption of Raung is different with the eruption of Merapi. The type of eruption of Merapi volcano, notes Surono, is accompanied by hot and eruptive clouds that glide up to tens of kilometers.
He thinks that the energy emitted by the Raung gradually since 2011 will not create a large eruption. This is different when there is obstruction of volcanic conduits, making it dangerous eruption when the stored energy is suddenly released.
« Well, it’s different on the Raung. Here there is no obstruction , so no energy accumulation . So for now, but is not excluded, the Raung will not have a huge crisis, » -he said.
