The danger light for the Colima Volcano of Fire remains on alert for passive degassing, with ash expected to fall in the vicinity of the volcano. The National Meteorological Service (SMN) is monitoring the volcano continuously to provide timely warnings of changes in activity.
Weather forecast for the volcano area
Cloudy skies, with limited visibility toward the volcano, making observation difficult in the event of a water vapor, gas, and/or ash exhalation (Image 1). The volcano is in the passive degassing stage. More information can be found in the Colima Volcano Weekly Technical Bulletin from the University Center for Volcanological Studies of the University of Colima (UCOL-CUEV). Manzanillo Colima atmospheric radiosonde, 6:00 a.m. local time, June 10, 2025: At 5,000 m: East-southeast wind at 39 km/h. Between 5,000 and 7,000 m: Southeast wind at 36 km/h. Above 7,000 m: East-southeast wind at 31 km/h.
There is cloud cover over the volcano area, which would hinder the detection of volcanic activity through satellite observation (Image 2). Satellite rainfall estimates show no accumulated precipitation over the volcano area in the last three hours, as of 12:00 p.m. local time today.
Ash Trajectory
In the event of any exhalation of volcanic ash, gas, and/or water vapor, the trajectory forecast by the Hysplit (Hybrid Single-Particle Lagrangian Integrated Trajectory) model, run by CONAGUA-CGSMN with a potential emission height of 500 meters above the volcanic cone, which is 3,839 meters AMSL (above mean sea level) (2,745 meters AGL), indicates westward trajectories, shifting to east-northeast and east (simulating exhalation every subsequent hour, 6 hours), as they pass through the northeast, north, and northwest of the state of Colima and the south, south-southwest, and south-central parts of the state of Jalisco, for the first 12 hours of the forecast. (2:00 PM to 2:00 AM local time). For the last 12 hours of the forecast (2:00 AM to 2:00 PM local time), the trajectories will continue over the south-southwest, south-central, central, southern, east-southeast, and eastern parts of the state of Jalisco and the west-northwest, northwest, and northern parts of the state of Michoacán. These trajectories predict the main direction of emissions from the plume of gas, water vapor, and/or volcanic ash originating from the Fuego volcano in Colima.
Under the administration of Lázaro Cárdenas, the Nevado de Colima Volcano National Park was created on September 5, 1936, covering 6,554.75 hectares. The Colima Volcanic Complex is located within this park, formed by the Fuego and Nevado de Colima volcanoes, the former being one of the most active volcanoes in Mexico.
This park is highly significant as a Federal Protected Natural Area, not only for its volcanic activity, but also for its diverse ecosystems, which are due to a number of factors such as its volcanic origin, complex topography, high altitudes, isolation from other mountains, and proximity to the Pacific Ocean.
The Colima Volcano is classified as a stratovolcano due to its structure, formed by several layers of solidified lava and marine sedimentary rocks, among others, and has an impressive geological history. Studies indicate that its composition contains Jurassic rocks and Cretaceous limestone, as well as granite formations spanning the Cretaceous to the Quaternary.
The colossus is known for its frequent activity, but Popocatépetl is considered the most dangerous in Mexico due to its proximity to populations. However, the park has the status of a protected area, allowing visitors to engage in activities such as hiking, camping, and volcano observation from viewpoints.
This park is preserved not only to protect its rich biodiversity, but also so that future generations can enjoy and learn from this unique ecosystem, reinforcing the importance of caring for these natural spaces. The area’s landscape is characterized by slopes covered in pine and oak forests, which contrast with the lower-altitude semi-tropical areas. This variety of ecosystems is home to a rich biodiversity, with numerous endemic species of flora and fauna.
