Chile's Calbuco volcano erupts for first time in more than 40 years

Story highlights

  • Almost 2 feet of ash fell in some areas
  • Authorities evacuate 4,400 people
  • The last time Calbuco erupted was 1972

(CNN)Chile's Calbuco volcano erupted twice in 24 hours, the country's National Geology and Mining Service said early Thursday.

The agency said it was evaluating the spectacular nighttime eruption, but indicated it was "stronger than the first one."
    About 23½ inches (60 centimeters) of ash fell in some places, according to the Ministry of Interior and Public Safety.
    Authorities issued a red alert for the towns of Puerto Montt and Puerto Varas in southern Chile. Both are popular tourist destinations.
    A 12-mile (20 kilometer) exclusion zone was established around the crater. Military and police forces were assisting with the evacuations of more than 4,400 residents, the Interior Ministry said.
    American Helen Rodgers witnessed the volcano erupt from the Hotel Patagonico in Puerto Varas, a popular tourist destination.
    The first eruption on Wednesday set off a bit of a panic in the region.
    "At the beginning, it was small, and later, the cloud grew and later there was a huge cloud over you and true terror starts," said one Puerto Montt resident.
    Another person said: "It was impressive to see an enormous mushroom cloud, with the immense force of the volcano, and to see the ashes. At that point, there was a lot of panic, lots of chaos, traffic jams, people going to supermarkets, everyone looking for water, trying to take out money from the ATMs."
    The eruption is a first for many in the region. The last major eruption was 1962. There was a minor eruption in 1972.
    Calbuco also belched out a bit of gas and smoke in 1996.
    Alejandro Verges, regional director at the Ministry of Interior and Public Safety, said Thursday afternoon that officials are concerned there might be a third eruption.
    "The situation is relatively calm right now, although people are understandably anxious about what could happen tonight," he said.
