More astonishing, apocalyptic images of a volcanic eruption have emerged from Chile, this time from Villarrica in the south of the country. A band of cloud had wrapped itself around the peak as lava spewed into the air, giving the entire landscape an eerie blood-red glow. Villarrica, located near the popular tourist resort of Pucon around 750 km (460 miles) south of the capital Santiago, is among the most active in South America. On March 3 a short-lived eruption of ash and rock led to the evacuation of thousands from the nearby area.
Britain’s Met Office told MailOnline that the clouds wrapped around the volcano are lenticular clouds, which are formed, it said, when the air is stable and winds blow from the same or similar direction at many levels of the troposphere. It said: ‘As the wind blows across hilly or mountainous regions, the air undulates in a downstream train of waves. If there is enough moisture in the air, these waves will condense to form the unique appearance of lenticular clouds. The clouds can be seen as far as 60 miles downwind of the hills or mountains that led to their formation and they are believed to be one of the most common explanations for UFO sightings across the world.’ FULL REPORT
