Parts of Cebu record “Good” air quality after the eruption of Mount Kanlaon, but environmental authorities warn residents to remain alert for possible acid rain. In advisories following the July 9 eruption, the Department of Environment and Natural Resources in Central Visayas (DENR-7) reports that prevailing wind patterns may carry volcanic gases toward Cebu, which can contribute to acid rain even when particulate readings look safe. DENR-7 states that current air quality in areas covered by its monitoring has returned to the “Good” category, with particulate levels within acceptable ranges. However, the agency emphasizes that the ongoing activity of Mount Kanlaon continues to pose environmental risks. The volcano remains under Alert Level 2, according to DENR-7. Officials urge the public not to relax precautions, indicating that conditions can change as winds shift and volcanic emissions continue. The advisories focus on maintaining vigilance for health and environmental effects associated with volcanic gases, including the potential for acid rain, despite the improvement in measured air quality.
