Ash Clouds from Puyehue-Cordón Caulle Continue to Disrupt Flights in Southern Hemisphere

The ash clouds have severely affected airline operations in South America.
Among the hardest hit airlines are Chile’s LAN and Brazil’s TAM and Gol, media reported.

“There are no signs that the situation is going to change or stabilize in the short term,” said director of Chile’s national service of geology and mining (SERNAGEOMIN).

“Fine ash, like we have seen from this latest eruption, could last (in the air) for months. If the ash column continues to measure up to 5.5 miles, it can spread easily. The higher the ash, the more it is blown elsewhere.”


Continuous eruption from Puyehue-Cordón Volcano Complex in Chile continues to eject large plumes of ash and volcanic gasses into the atmosphere, depositing thick layers of ash east of the volcano, as shown in this image captured by MODIS on the Terra satellite on June 13. The large mountain of ash could lead to deadly landslide and lahars, NASA reported SERNAGEOMIN as saying. Meantime, the ash is disrupting flights as far away as Australia and New Zealand.

Ash from Puyehue Cordón Caulle over Australia and NZ

Posted by feww on June 14, 2011

Ash clouds from Puyehue Cordón Caulle continue to disrupt Australia, NZ flights


The ash plume from Puyehue Cordón Caulle covers southern Australia and the Tasman sea (above), as well as New Zealand and the South Pacific Ocean (below).

Puyehue-Cordón Caulle in Chile exploded on June 4, 2011 sending an ash plume to a height of about 16km, towering above the local clouds.

Airline Flights

Australian airline Qantas said it was too dangerous to fly through the thick clouds of ash drifting over the Pacific Ocean from  continuous eruption at CORDON CAULLE volcano in the Puyehue Volcano Complex, Chile. Accordingly, it has cancelled all its flights to and from Melbourne. The decision follows earlier flight cancellations in and out of Tasmania and most of of New Zealand.

All other airlines, with the exception of Air New Zealand, have also grounded flights in the region.

The logic-defying Air New Zealand is risking the lives of its passengers by worming in out of the ash clouds, trying to dodge the worst of the plumes. The airline said it was adjusting flight paths to steer aircraft below the ash!!

The Civil Aviation Authority of New Zealand said they felt comfortable with Air New Zealand flight continuing below 20,000feet (6 km) because most of the ash appeared to be above that altitude.

“[Air New Zealand general manager airline operations and safety Captain] Capt Morgan said the MetService had advised that the ash cloud was now much higher and the Civil Aviation Authority was comfortable for domestic and trans-Tasman services to continue to operate.” a report said.

Air Travelers Don’t Seem to Get the Message!

Watch out for multiple planes falling out of the sky in the coming months due to “unknown” or “mysterious” causes.

Puyehue ash raises river temp, kills salmon stock

Posted by feww on June 11, 2011

Hot pyroclasts from ongoing Puyehue eruption raise River Nilahue temp to 45ºC (113ºF)—a rise of 35ºC

Tens of thousands of tons of hot volcanic materials from the ongoing Puyehue eruption have raised the temperature of Nilahue River to 45ºC (113ºF)—a rise of 35ºC, compared with seasonal average—contaminating the water and killing a large number of salmon, Chilean Public Works Minister.

The area near the Nilahue and GolGol rivers basin was evacuated on June 10, 2011 after the two rivers overflowed their banks, blocked by volcanic debris. The river flow rose by more than five fold, from 30 cubic meters per second (cmps) to more than 160 cmps, the minister said.

Air Travel

Flights from several airports in Argentina, Uruguay and southern Brazil. remain grounded for a third day on Saturday.

“At least six international carriers suspend flights between Buenos Aires and cities in US, Europe and South America,” a report said.

“Many flights from airports in southern Brazilian cities such as Porto Alegre and Florianopolis – some 2,500km (1,550 miles) from the volcano – were cancelled on Friday,” according to another report.

San Carlos de Bariloche

Meanwhile, in the ski resort city of San Carlos de Bariloche,  workers removed about 15,000 tons of volcanic ash (600 truckloads) from the airport’s main runway on Thursday.  Authorities said the airport would remain closed at least until June 21, AP reported.

Massive Eruption Covered Large Regions in Ash and Pumice

The Eruption Aftermath

The volcanic ash blanketed the Andes and Patagonia regions with a thick blanket of ash and pumice before reaching the Argentine Atlantic Coast. The cities affected by the ash included Puerto Madryn and Trelew, in Chubut, as well as the towns of San Carlos de Bariloche and Villa La Angostura, a report said.

“Local authorities assured there is a layer of ash that’s at least 30 centimetres high over the National Route 40 in the area close to Bariloche and Neuquén. Border patrol has discouraged residents from driving in the area.”
