An overview of Colima was completed on September 30:
The dome-flow reaches a length of about 300 meters and a volume of 750,000 m³. His progress in the slope leads to rockfalls and small pyroclastic flows.
Intense fumarolic activity, steam and magmatic gases, mark several mouths on the summit dome; fumaroles reach 3,500 meters above the crater. This activity is interspersed with moderate explosions.
The state of Colima has extended the exclusion zone to 12 km from the crater. It remains at 7.5 km for Jalisco.

The southern and southeast flanks are marked by rock falls and pyroclastic flows, but it's especially the barranca Montegrande that is concerned with the risk of lahars that would affect the lower parts.
Following the intense activity, the Scientific Committee decided to evacuate the communities of La Yerbabuena and La Becerrera.
