Landslide provokes volcano fears in northern Peru 21 February 2010

Peruvian news outlets are full of reports of a landslide in San Luis de Lucma district, Cutervo Province, which is in the northern Cajamarca Region of Peru. This is not a part of the country normally associated with volcanic activity (in Peru the active volcanoes are found in the far south), but local inhabitants apparently believed that a volcano was erupting and asked to be evacuated: local sources say up to 2000 people wanted to be moved out. Some news reports speak of an ‘explosion’ and dust clouds including ‘sulphur’:

The strange event occurred at approximately one in the afternoon, affecting about 20 hectares of farmland, where at the moment of the explosion there were people working their lands with their animals, who have been buried. The mayor of San Luis de Lucma, Santos Delgado Fernández, said that there were at least 100-150 victims after the blast, the majority residents of villages around the scene of the incident. ‘They have lost crops and animals’, he said. Local inhabitants said that after the explosion took place the area was transformed into a dust cloud, putting the health of hundreds of locals at risk through the emanation of smoke and sulphur that can cause asphyxiation.

Landslides are not uncommon in Peru and can be deadly, particularly in the rainy season (a fatal landslide occurred last month in the south). This area of northern Peru has no history of volcanic activity so the fears of a volcanic eruption are almost certainly the products of panic and a misunderstanding of the nature of the event. The local head of Civil Defence, Miguel Alva, is quoted as saying that this was a landslide, and that it is not uncommon for landslides to generate ‘a large cloud of smoke’. Similarly, the director of seismology at the Instituto Geofísico del Perú, Hernán Tavera, has affirmed that this was a landslide caused by recent rains and not a volcanic event: ‘There is no volcano in the country north of Ayacucho’. The blast and smell of sulphur, Tavera says, would have been caused by the disruption of thermal springs in the area of the landslide.

The landslide has disrupted local water supplies and affected a nearby hydroelectric plant. Around 300 people were affected by the event, and latest reports say that eight people are missing and five houses were buried.

El Misti at the NASA Earth Observatory 2 November 2009

El Misti volcano and Arequipa, Peru, 16 October 2009 (NASA astronaut photograph)

The Peruvian volcano El Misti is very close to the country’s second city of Arequipa: just 17 km separates the city with its ~1 million inhabitants from the volcano’s crater. The image above, a mosaic of two ISS astronaut photographs that is today’s Image of the Day at the NASA Earth Observatory, shows the potentially dangerous relationship clearly. Larger versions of the image, and a full commentary, are available over at the Earth Observatory. There is, however, no scale bar on the Earth Observatory images, so I have added one to the small version above.

Peru practices for El Misti eruption 17 May 2009

El Misti in southern Peru, a 5822-metre stratovolcano, has an active eruptive history and last erupted in 1985. The volcano overlooks the city of Arequipa, which has a population of 1.2 million people. El Misti’s recent activity has been on a relatively small scale (no eruption larger than VEI=1 since the fifteenth century) but it poses a potential danger to thousands of people — about 2000 years ago a pyroclastic flow from the volcano travelled some 12 km, and winds have spread ash as far as 20 km from the cone.

In July 2001 a NASA commentary noted that the local civil defence and planning authorities regard the volcano as a ‘remote danger’ and that the city of Arequipa is continuing to expand towards the volcano. It seems, however, that some of the Peruvian authorities are now aware of the dangers: Peru.com reports that an exercise has just been held to simulate the evacuation of nearby districts in the event of an eruption. The exercise was organized by Peru’s Instituto Geológico, Minero y Metalúrgico (INGEMMET) with the local authorities in Arequipa and neighbouring areas and the Peruvian Army. Sirens sounded, trucks carried evacuees to shelters, procedures for providing tents, warm clothing, blankets and food were tested. The practice evacuation involved only 150 people, but the aim was to ‘sensitize’ the local population about the dangers of an eruption and the importance of being prepared.
