Volcanic eruption in Ecuador

Since October 2007, the Tungurahua volcano has been showing sustained increased activity, particularly in the number and size of explosions. This activity increased on 29 December, when the number of explosions registered in one day exceeded 100. On 2 January 2008, the highest number of explosions was registered since September 2006. On the 6 January, nearly 1,000 people were evacuated. Seismic activity has intensified, and at present is similar to that registered in May 2006, previous to the eruptions and pyroclastic flows of July and August that same year.
