The main alert remains in Oaxaca and in several regions of the country, such as the Yucatan Peninsula, due to the activity of the Popocatepetl volcano, after it erupted and its emissions are presumed to be affecting the climate in Yucatan and other areas of the country.
While the DN-III plan remains active in Oaxaca to prevent harm to the population, the effects of the volcano extend beyond the area. It has been revealed that the emitted gases, particularly sulfur dioxide (SO2), could spread over the southeastern region of the country.
Experts indicate that there is a high concentration of SO2 in the central part of the country due to the volcano’s effects. However, currently, the winds in the lower and middle layers of the troposphere are blowing from the west or west-northwest, suggesting that the SO2 cloud would be moving towards the Gulf of Mexico.
Forecasts indicate that the winds would be carrying the SO2 clouds to states in the southeast such as Tabasco, Oaxaca, Veracruz, Chiapas, and possibly Campeche and Yucatan.
According to specialists, high concentrations of SO2 can be harmful to health, although it depends on proximity to the surface.
It is worth noting that when the Popocatepetl volcano erupts, it emits sulfur dioxide (SO2), which, when combined with water (H2O), forms sulfuric acid (H2SO4), resulting in acid rain. When a storm cloud forms, it is located between 1.5 and 12 kilometers, suggesting that there could be a concentration of sulfuric acid in areas where it rains, and currently, there are rainfall forecasts for the southeastern part of the country.
