Volcanic ascents: cautionary tales from Villarrica 6 January 2010Posted by admin in Chile, natural hazards, Villarrica.

Villarrica volcano in Chile, one of the country’s most active volcanoes, is popular among walkers and climbers, who come to the Parque Nacional Villarrica to enjoy the beautiful scenery and (when Villarrica’s activity allows) the challenge of ascending the 2,847-metre volcano’s slopes. But a volcano does not have to be erupting to be dangerous, and Villarrica certainly has its dangers.
On Saturday 2 January a snow avalanche struck a party of tourists who were climbing to the summit crater, leaving one Brazilian tourist seriously injured and a number of his companions slightly hurt. The avalanche, reportedly 100 metres in width, occurred in good weather conditions and took the party (and their mountain guide) completely by surprise. This is the first time such an avalance, apparently caused by unstable snow cover slipping on the underlying ice, has caused problems at Villarrica. In response, the park authorities closed the slopes to tourists pending a detailed survey of snow and ice conditions on the volcano.
The picture above (copyright Roberto Alarcón N.), kindly submitted by Werner Keller of Proyecto Observación Volcán Villarrica (POVI), shows Villarrica on 2 January 2010 following the avalanche referred to above and two further avalanches; the scars are clearly visible in the snow. The avalanche struck the tour party at around 2000 metres a.s.l., having descended about 600 metres, accumulating loose volcanic debris on the way. The front of the avalanche lobe was 2-3 metres deep. More information can be found at the POVI website.
These latest events make an article published by the Spanish newspaper ABC at the end of December particularly timely. ‘Los israelíes y el volcán Villarrica’ is subtitled ‘the volcano holds within dozens of tragic stories’. Villarrica is the centre of ‘a real tourist bonanza’, says the article, ‘visited annually by thousands of climbers who long to conquer it’, but many are ill-prepared for the ascent: ‘”People have lost respect for the volcano,” says one of the guides who accompany the kids on their route to the summit. “They come without the things they need. They think it’s a game, then get us out to rescue them.”‘
Villarrica is a particularly popular climb among young Israelis preparing for service in the Israel Defence Forces. As one of the guides explains, ‘they mostly come without experience and with insufficient equipment. They think it is the desert and are not properly equipped’. Some have even died on Villarrica, which is why climbers heading for the summit pass a memorial to two Israelis killed while climbing the volcano in April 1987. The climbers keep coming, however, including many Israelis, put off neither by the grim memorial nor by the fact that if they do get into trouble they will be liable for the costs incurred in rescuing them.
