 Seismic recording from Nevado del Huila 31 July - 1 Aug Sunday, May 16, 2010
In their latest bulletin on 11 May 2010, INGEOMINAS warns of a possible new eruption in the near future at Nevado del Huila volcano, after recording an alarming number of seismic events under the volcano and an important SO2 emission, which likely shows magma movements inside the volcano.

Based on seismic interpretation, INGEOMINAS reported ash emissions from Nevadodel Huila during 27 May. Thursday, Apr 26, 2007
Based on satellite imagery, the Washington VAAC reported that an ash eruption from Nevado del Huila on 18 April produced a plume that drifted SW and dissipated. On 22 April, INGEOMINAS reported that during aerial observations, fumarolic activity was observed from a fissure first noted on 19 February. The fissure was approximately 2.3 km long and 0.2 km wide. A resultant plume rose to an altitude of 10.4 km (34,100 ft) a.s.l. Another fissure, extending about 2 km from the SW to the NE sector of Pico Central, also produced fumarolic emissions. Mudflows in the Páez and Símbola rivers originating on Pico Central primarily swept through the Oso ravine on the E flank and Bellavista ravine on the W flank.According to news articles, the eruption during 17-18 April caused damage to houses and destroyed 19 bridges along the Páez and Símbola rivers. Several kilometers of a highway, used to transport goods and medicines to the population, were also destroyed. INGEOMINAS noted that there were no reported deaths or injuries as a result of the eruption. Thursday, Apr 19, 2007
On 18 of April, Nevado del Huila had a moderately strong ash eruption causing ash fall and lahars on its flancs due to melted snow and ice water. About 8000 people have been evacuated. After the explosion, seismic activity at the volcano has decreased again. Sunday, Feb 25, 2007
NGEOMINAS reported increased seismic activity and two explosions from Nevado del Huila on 19 February. An ash plume rose to an altitude of approximately 6 km (19,700 ft) a.s.l. During aerial observations on 20 February, ash deposits were seen on the W sector of a summit glacier and dispersed to the NW. Fumarolic plumes originating from several points along a fissure rose to 7 km (23,000 ft) a.s.l. Small mudflows from a glacier traveled down a gorge. Based on news reports, small avalanches prompted officials to order evacuations from towns bordering rivers. Thursday, Feb 22, 2007
