Mount Agung or Gunung Agung is a active volcano in Bali. This stratovolcano is the highest point on the island. It dominates the surrounding area influencing the climate. The clouds come from the west and Agung takes their water so that the west is lush and green and the east dry and barren.

At the surface, the explosive activity of the volcano has been declining during the past week and the ash and steam emissions have decreased considerably. Only a weak steam and gas plume has been observed since yesterday from the crater.However, this apparent calm does not mean at all that the eruption is over. Rather that its style is changing: it has entered a more effusive stage, with viscous lava accumulating in the summit crater as a new lava dome, which is what volcanologists have recently confirmed according to an article in CNN Indonesia referring to PVMBG, the Center for Volcanology and Mitigation of Geological Hazards,.If their information is right, Agung's new lava dome has already grown to approx. 30 million cubic meters of volume, and it is estimated that this corresponds to about 50% of the available magma volume ready to erupt.The pace of growth has been worryingly fast: within a few days, the total volume of the dome was claimed to have increased by 10 million cubic meters.Based on such estimates, the eruption could fill the crater (about 900 m wide and 200 m deep and thus has a capacity of 60 million cu meters) within the next 5-10 days only. At that stage, the eruption will become extremely dangerous: when lava starts to spill over the crater, the viscous, blocky lava will likely generate hot avalanches (pyroclastic flows), that can travel for many kilometers at high speed and devastate everything in their path.However, this scenario will only happen if the supply of magma is large enough and the eruption still continues, something difficult to know. On the other hand, it seems rather likely that the magma supply is far from being exhausted at the moment: tremor episodes related to magma flowing upwards inside the conduit continue to occur, and ground deformation measurements indicate continuing inflation of the edifice, both indications that more magma is going to be erupted.PVMBG plans to monitor the crater visually by a drone, but has been facing technical difficulties.
