Which risk acutely increases following significant tephra fallout?

💡 Explanation

Asphyxiation events rise because volcanic ash inhalation burdens respiratory systems with fine particulate matter, inhibiting gas exchange; therefore, air quality plummets post-eruption leading to acute respiratory illness rather than the other indirect options.
