How CityAir Monitors may be used for volcanic eruptions control and notifications

One on the CityAir Monitors is located in the closest proximity to acting Volcano Ebeko, Kuril Islands.

Starting from 2016 and on a regular basis Ebeko erupts columns of ashes and gas-vapour clouds. On April 6, 2021 another ashfall occurred and reached the altitude of 2km with a plume dispersion of 5 km. The satellite picture shows the plume moving towards the city area.

But the situation has no reason for concern - the maximum AQI defined was 5 out of 10. And CityAir monitors registered some sulphur gases already on the eve on April 3 - you may see that on the diagram.
