    Aircrafts Warned to Avoid Airspace near Pavlof Volcano

    On November 15, the National Weather Service warned the aircrafts to avoid airspace near erupting Pavlof Volcano in Alaska, which is spewing ash around 30,000 feet above sea level.

    The volcano began erupting lava from a vent near its summit a few days ago. On November 14, the ash cloud was recorded at 16,000 feet. Dave Schneider from the Alaska Volcano Observatory said that the eruption became more intense at 6 a.m. on November 15, further rising the ash cloud.

    According to Schneider, the eruption can last for several weeks or months with fluctuations in intensity.

    Volcano Nabro erupted today throwing ash clouds up to 13.5 kilometres.The Volcanic Ash Advisory Center (VAAC) said Monday that the 5,331 ft volcano has resulted in a large ash plume of up to 13.5 kilometres (8 miles) high. The scale of the eruption, compared to the ongoing eruption in Chile and 2010?s eruption at Eyjafjallajökull in Iceland, remains unclear. Ash is falling on the northern Ethiopian town of Mekele. The ash advisory issued by the VAAC (see below graphics) is predicting that the Ash plume will spread towards the Middle East Monday night.

    The Puyehue eruption began June 4th, 2011 when 3,500 people were evacuated. First the local airport was closed, then cancellation of hundreds of flights have continued this last week and a half. As of Friday, the cloud spread causing cancellations across South America towards Uruguay and into Brazil.

  • Return of the Volcano

    Saturday Iceland’s Grimsvotn volcano spewed a 7-miles plume of gas and ash. Initial warnings shut down airports in Iceland- (ISAVIA established a 120 mile no-fly zone around the volcano, closed Keflavik airport, and canceled all domestic flights.)

    Tuesday airports in Ireland will be shut down. Forecasts are tentative because there is uncertainty how the plume will interact with the weather, but it is not expected to be as overwhelming as last year’s eruption of Eyjafjallajokull.
