Earthquakes can affect atmospheric composition and air quality in several ways. One major impact is the release of dust, particles, and gases into the air during the seismic activity. This can lead to a temporary increase in air pollution levels, which may have negative effects on air quality. Additionally, earthquakes can also disrupt industrial facilities, causing potential releases of harmful chemicals into the atmosphere. Overall, earthquakes can have a short-term impact on atmospheric composition and air quality in the affected regions.
