Overview
- A cluster of hot-emitting surface holes that began on May 25 in El Salitre produced an initial water and steam jet about 15 meters high and temperatures measured up to about 97 °C.
- Field teams from UNAM, Universidad Michoacana, CENAPRED and Protección Civil found 11 emission points and detected gases including carbon dioxide, ammonia and hydrogen sulfide while finding no evidence of ascending magma.
- Officials carried out preventive evacuations of 13 people, reported the death of three pigs, established a roughly 30-meter safety perimeter and removed nearby gas cylinders and other hazards.
- A coordinated technical response is continuing with drones, thermography, gas sampling and ground-stability checks and agencies are preparing a joint technical report and sustained surveillance.
- The site sits on the Ixtlán fault inside the Transmexican Volcanic Belt and historical records from 1906 and 2017 show similar hydrothermal events, so residents are urged to watch for new cracks, vapor zones and to follow official safety guidance.
