There is a line of fissures to the north-west (these last erupted in 1960). The current eruption maybe along the 1960 fissure. Puyehue is unique in Chile, most volcanoes erupt basalt/andesite but Puyehue erupts rhyodacite/rhyolite.

Flights were cancelled for several hours in Uruguay and Argentina Tuesday due to volcanic ash from the four-month-long eruption of the Puyehue volcano in Chile, airport authorities said.
Laura Vanoli, Uruguay's chief aeronautic meteorologist, said the country was almost entirely covered by an ash cloud.

In volcanic terms, the ash and dust plume created by Puyehue-Cordon Caulle was modest, only reported to have reached a height of around 15 kilometres. Large explosions, such as the 1991 eruption of Mount Pinatubo in the Philippines, can create plumes in excess of 34 kilometres high and 400 kilometres wide, ejecting more than 17 million tons of aerosols.
But even as a modest eruption, the Chilean volcano could have ejected enough ash and dust into the stratosphere to have some long-term climatic effects, which could in turn affect agriculture and impact on human well-being and quality of life.
