This is certainly a concern at any time. I recall a person from AMOS studying volcanic activity and it’s impact on global climate.
When a volcano the size of Taal erupts and later enters a more explosive mode, aerosols that are ejected into the atmosphere can reach altitudes of 15 to 20 kilometres.
Check out the incredible photographs and videos of the volcano in the Philippines. The volvano erupted yesterday 100km south of Manila. More eruptions are expected that possibly could lead to a major one! The volcanic plume was impressive to watch causing catastrophic below.
