Volcanic Ash

Volcanic ash consists of fragments of pulverized rock, minerals and volcanic glass, created during volcanic eruptions. A severe volcanic eruption could generate significant amounts of sulphuric acid and lesser amounts of hydrofluoric acid, hydrochloric acid and very fine ash particles.

Gases in the atmosphere will be brought down to the surface throughout the United Kingdom and Northern Europe via dry precipitation (termed dry fog) and acid rain.

Risks of Volcanic Ash

These concentrations of sulphur dioxide will cause asthma attacks and worsening of the clinical condition of patients with other chronic respiratory disease. Due to its wide dispersal, ash can have a number of impacts on society, including: human and animal health; disruption to aviation; disruption to economic infrastructure (e.g. electric power supply systems, telecommunications, water networks, transportation); primary industries (e.g. agriculture); buildings and structures.

If there is a risk of volcanic ash clouds, be prepared for disruption and check before you travel anywhere.
