24. 12. 2018, the Sicilian volcano Etna woke up. By comparing it to other eruptions, we estimate the emissaries of very fine dust (PM 2.5, PM 10) to 2.3 million. tonnes/day. By comparison, the average brown coal-fired power plant meeting the current emission limits with a power of 700-800 MW will release a similar amount of dust in about 100 years of full power operation. Note. We consider the amount of output gas 4.4488 mil m3/h, output concentration 15 mg/m3, 365 days/year of operation.
