Puyehue Volcano Eruption Continues40.6S 72.5W
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.
