On June 4th, a volcano in southern Chile erupted, sending volcanic ash into the air. The large particles of ash soon dropped to the ground but the small particles were carried, high in the air, by the westerly wind to Australia and New Zealand. This is amazing. The distance at 40 degrees south from Chile west to New Zealand is about 20,000km. This volcanic ash has crossed Argentina, Uruguay, Brazil and the South Atlantic Ocean. It took about a week to arrive here.
On Sunday, QANTAS airlines and JetStar stopped flights across the Tasman to Australia. They also stopped flights in New Zealand and in parts of Australia. However, AirNZ continued to fly. AirNZ said the ash is high in the air between 6,000 and 10,000m. Their planes can fly below the ash, at 5,800m. This uses 10% more fuel but it is safe. QANTAS and JetStar believe it is safer to stop flights. Many passengers have been waiting in airports, hoping the volcanic ash will disappear. Today is the 4th day and it has not disappeared yet. In fact, the volcano is still erupting.
Fine particles of volcanic ash look like flour but they feel more like particles of sand. If they get into the engines of the plane, they can cause damage.
New Zealand has a Volcanic Ash Advisory System which can show the path of the volcanic ash.
