In the central Andes mountains, satellites have detected ground deformation under way above a major subterranean magma body. The Altiplano–Puna volcanic province is part of an active volcanic arc in South America’s central Andes. Extending through Peru, southwestern Bolivia, Chile and northwestern Argentina, it is home to a number of large calderas formed following catastrophic eruptions. Beneath the surface of Altiplano–Puna, about 17–19 km deep, lies the largest known active magma body in Earth’s continental crust.
Within the framework of the international Committee on SatelliteEarth Observation (CEOS), the Canadian Space Agency (CSA) is collaborating with NASA on various projects helping to monitor, manage and respond to natural disasters.
According to the National Meteorological Service, since 23 November 2009, the provinces of Chaco, Entre Rios, Corrientes, Santa Fe and Misiones have been affected by heavy rain and floods. The communities at risk are those in low level areas due to their proximity to the overflowed Parana river, Uruguay river and the Salado del Sur basin.
The Government reports that the Tartagal river has overflowed, resulting in mudslides flowing into much of the town. It confirms that there have been some fatalities. Source : Glide number
