Such new eruptions are likely to follow the style of the last explosion, a sudden vulcanian-type eruption: it was proobably caused by accumulating viscous magma trapped under a solid plug in the crater, which was eventually disintegrated during an explosion when pressure exceeded the strength of the plug.
According to volcanologist Hendrasto, head of PVMBG, there are 29 villages at risk within a zone of 6 km radius around the volcano.
