LATEST UPDATE (Dec.2/2010)
Volcanic activity has been reported in the Tungurahua (Throat of Fire) volcano in Ecuador, the second case sighted in the past few weeks. The volcano spewed molten rocks and large clouds of gas and ash near Banos, south of Quito, Reuters reported on Tuesday. The Tungurahua’s volcanic activity follows last month’s eruption, when a column of gas shot up seven kilometers into the sky. No casualties have been recorded so far, but flight re-direction is being considered.
Tungurahua is located approximately 150 kilometers southeast of Ecuador’s capital, Quito.
RECENT CHRONOLOGY ….
After almost 6 months of relevate calm, Mount Tungurahua seems to be reawaking in the first days of 2010.
DEC.30 2009 – long-period earthquake followed by fumarolic activity with a steam plume reaching 300 metres above the crater.
JAN.01 2010 – beginning of emissions with low ash content, accompanied by rumbles that have gradually increased their intensity.
JAN.03 2010 – crater glow visible, lava fountaining begins, with the projection of incandescent material onto the upper slopes and intense rumbling sounds
JAN.04 2010 – increased ash emissions with eruption columns reaching as high as 2 km above the crater, ash fall reported to the west.
MAY.31 2010 – explosion (see photo series below)
NOV.22 2010 – A sudden eruption of the Tungurahua volcano in the Ecuadorian Andes sent a column of ash more than 7 kilometers (4.3 miles) into the sky.
APR.27 2011 – A significant explosive eruption occurred, prompting evacuations of schools and villages near the volcano. Tungurahua produced a 7 km / ~23,000 foot ash plume, which is a bit surprising considering that last report from Instituto Geofisico in Ecuador from January 2011 reported “activity at Tungurahua continued to decrease and ash was absent from plumes.” Hugo Yepes, a geologist from the IG, was quoted as saying (Spanish) this eruption was one of the largest at the volcano in the past 11 years and that the IG expects that this eruption might gone on for “several days”. The Ecuadoran government placed the volcano on Orange Alert status, meaning mandatory evacuations for a number of villages near Tungurahua. Some air traffic in and out of Quito has also been effected by the eruption.
COTALO, ECUADOR – The Tungurahua volcano spews ashes and lava on January 11, 2010, in Cotalo, Ecuador, 135km south of Quito.
