Ash East of Rio de la Plata Estuary - July 23rd, 2011

After a quieter spell, Chile’s Puyehue Volcano released a large cloud of ash once again in late July (click link for more on the 2011 Puyehue volcanic eruption). The eruption began on June 4th.

While the main image focuses on the volcano itself, the detail image shows the ash cloud spreading east of the Rio de la Plata estuary. A change in wind direction caused the ash to blow over the estuary itself, causing flight cancellations from Buenos Aires and Montevideo.

Ash from the 2011 Puyehue volcanic eruption, which began on June 4th, spreads from Chile, across Argentina, and out over the Atlantic Ocean.

The ash has precipitated over the Argentine cities of Villa la Angostura, Bariloche and the northern part of Chubut province.

Here, the ash cloud veils reservoirs by the confluence of the Neuquén and Limay Rivers in Neuquén province.  It reaches eastward to Bahía Blanca, and northeast to Buenos Aires, where it can be seen in the skies over the sediment-laden Rio de la Plata estuary.

Close-up of Ash

Ash from the eruption of the Puyehue volcano, in Chile, reaches all the way across the Atlantic Ocean to South Africa, a distance of over 4800 miles (7725 kilometers). Here, the plume of ash  can be seen crossing the southern part of the country, north of Cape Town.

The eruption began in the Puyehue-Cordón Caulle volcanic complex in Chile on June 4, 2011. At least 3,500 people were evacuated from nearby areas, while the ash cloud caused airport closures in neighboring Argentina, and later disrupted flights in places as far away as Australia and New Zealand.

Cloud of Ash Spewing from Iceland’s Grimsvotn Volcano – May 26th, 2011

Iceland - May 23rd, 2011

This image shows a cloud of ash spewing from Iceland’s Grimsvotn volcano, a vision reminiscent of the 2010 eruptions of the Eyjafjallajökull volcano (click here for previous articles). The Grimsvotn volcano is located under the Vatnajokull glacier in the Vatnajokull National Park – the biggest national park in Europe.

Although the eruption temporarily affected European air travel, with about 700 flights cancelled in Germany on Wednesday, air traffic is now operating normally. In Iceland, clean up of the ash has begun, and all major roads have been reopened.

Eyjafjallajokul Volcano Sends Ash Due East – May 13th, 2010

Despite the clouds covering most of Iceland and the surrounding ocean, the location of the volcano Eyjafjallajokul is easily pinpointed at the origin of the plume of ash. At the time this image was taken, winds were blowing the ash due east.

On May 11th and 12th, the volcanic ash cloud from Iceland reached the air space of Turkey as well as North African countries. Around 5 airports in Morocco were shut down as a precautionary measure due to the ash cloud.

The ash cloud from the 2010 Iceland volcano also closed airspace over Southern Spain, which caused airports to be shutdown in some Spanish Islands. Turkey affected by the volcanic ash as previously mentioned, but 2 airports were functional in Istanbul.
