Description of Event
More than 100 seismic shocks were felt on 19 February 2007 in the departments of Cauca, Valle, Huila, and Tolima in Colombia, followed by two explosions at the Volcán Nevado del Huila on 20 February at 8:30-8:50 local time, with a column of ash and gases reaching some 700 meters. At 11:50 a substantial rise of the level of the Paez River at Balacázar (Cauca) was reported. People living near the river as well as near the Simbalé, Magdalena, and Negro rivers have been advised to move to higher areas to avoid mudflows resulting from the melting of the snowpack of the volcano.
