Chile's Puyehue volcano spews lava 

June 22, 2011 (The Sydney Morning Herald)

    But the ash cloud created by the eruption continues to wreak havoc on airlines around the world.
    The Chilean airline LAN cancelled flights to Temuco and Valdivia in the south of the country, and a number of flights were suspended in Australia and New Zealand.

    "Viscous lava has flowed slowly westward in a channel roughly 50 metres wide and 100 metres long," the national geology service known as SERNAGEOMIN said in its latest report.
    Last week, SERNAGEOMIN chief Enrique Valdivieso said the appearance of lava would signal "the end of the eruptive process" and would not put any of the local population in danger.
    Authorities had subsequently authorised the return of more than 4,000 people to their homes.
    But on Tuesday, SERNAGEOMIN acknowledged that "eruptions continue" and that volcanic activity could "increase again."
    Puyehue had been dormant for a half century until June 4.


    Air traffic in the southern hemisphere was hit especially hard, initially paralysing airports in Buenos Aires and Montevideo, and later those in Australia and New Zealand.



    Ash poses a significant threat to aircraft because once sucked into engines, it can be transformed into molten glass by the high temperatures and potentially cause an engine to fail.
    The eruption of the Icelandic volcano Eyjafjoll last year caused the greatest shutdown of air space in peacetime Europe, with more than 100,000 flights cancelled and eight million passengers affected.
