Galeras Erupts Again!

Galeras forceful eruption prompts evacuation

Galeras, a stratovolcano, located near the regional capital city of Pasto in southwest Colombia and close to the border with Ecuador, erupted again on Saturday, prompting the authorities to issue a “red alert” for the area. An evacuation order was issued for about 8,000 people who live in the vicinity of the volcano.

The Colombia Institute for Geology and Mines said the blast occurred at about 12:10 UTC Sunday. No fatalities or injuries were reported.

According to the local government  “large amount of ash” was falling on Pasto.

The 4,270-meter volcano has been an active volcano for about a million years and is considered the most active volcano in Colombia. In 1991 it was designated a Decade Volcano due to its proximity to the city of Pasto.

On January 14, 1993, during a Decade Volcano conference in Pasto, a group of unfortunate scientists launched an impromptu expedition to the volcano’s crater. Shortly after their arrival, Galeras erupted killing six scientists and three others.

In the 20th century Galeras underwent several episodes of unrest including those in December of 1923, October of 1924, October of 1932, February of 1936, July of 1947, January of 1950, February 1974, February of 1989, January of 1990, January of 1993, March of 2000, June of 2002, July of 2004, November of 2005, October of 2007, and several episodes in 2008 and 2009.

    Colombia’s Galeras volcano erupts

    BOGOTA (AFP) — Galeras volcano in southern Colombia erupted on Friday for the second time in less than a week, sending ash raining down but no causing no victims or damage, the Colombian Institute of Geology and Mines said.

    A forceful eruption began at 7:05 am (1205 GMT), residents reported from the city of Pasto, at the foot of the volcano.

    The regional alert system was raised to its highest level, the institute said in a statement.

    The eruption was “accompanied by shock waves,” generating vibrating effects and audible rumbles, the institute said.

    Speaking on Caracol radio emergency official Luz Amanda Pulido reported ash was falling and that contingency evacuation plans were in place if the situation worsens.

    It follows a similar eruption late Saturday at the volcano, which is located near the border with Ecuador. That eruption caused no casualties or damage, although emergency procedures began to evacuate 8,000 residents.

    The 4,270-meter (14,009-foot) Galeras has stirred sporadically in recent years. It erupted in January 2008, causing no casualties, but a 1993 eruption claimed the lives of nine people.
