A volcanic eruption in which country caused travel chaos and many cancelled flights in the southern hemisphere last month?
2011 Puyehue-Cordón Caulle eruption 2011 Puyehue-Cordón Caulle eruption The 2011 Puyehue-Cordón Caulle eruption () was a volcanic eruption that began in the Puyehue-Cordón Caulle volcanic complex in Chile on 4 June 2011. The eruption occurred from the Cordón Caulle fissure after 51 years of the volcano being inactive. At least 3,500 people were evacuated from nearby areas, while the ash cloud was blown across cities all around the Southern hemisphere, including Bariloche, Buenos Aires, Montevideo, Stanley, Porto Alegre, Cape Town, Hobart, Perth, Adelaide, Sydney, Melbourne, Wellington, Auckland and Port Moresby, forcing airlines to cancel hundreds of international and domestic flights and causing travel chaos.
Air travel disruption after the 2010 Eyjafjallajökull eruption ash cloud during the period of disruption. Air travel disruption after the 2010 Eyjafjallajökull eruption In response to concerns that volcanic ash ejected during the 2010 eruptions of Eyjafjallajökull in Iceland would damage aircraft engines, the controlled airspace of many European countries was closed to instrument flight rules traffic, resulting in the largest air-traffic shut-down since World War II. The closures caused millions of passengers to be stranded not only in Europe, but across the world. With large parts of European airspace closed to air traffic, many more countries were affected as flights to, from, and over Europe were cancelled.
