Emissions have increased there as a result of earthquakes of 14-15 August, which caused damage in the Colca Valley.
Volcanologists have noticed an increased of activity in one of three fields fumaroles, which covers an area of ​​300 meters by 60. This zone is characterized by the presence of sulfur, which gives it a yellow tint and a temperature above 80 ° C .

The emergence of two new points of emission of SO2 and water vapor, one located on the edge of the crater, the other in the lower part of the northern flank.
