Animals During Volcanic Eruptions: Evacuation, Injury, and Recovery

Volcanic eruptions threaten wildlife and livestock through ash fall, lava flows, toxic gases, and landscape destruction. Animal welfare is rarely prioritised in eruption response plans.

Key Facts

Volcanic ash causes severe respiratory damage in livestock and wildlife within hours of heavy fall
Livestock cannot typically be evacuated quickly enough when eruptions occur without warning
Birds and small mammals suffocate or are poisoned by volcanic sulphur dioxide at higher concentrations
The 2010 Eyjafjallajokull eruption in Iceland caused significant livestock welfare problems from ash ingestion
Hawaiian lava flows in 2018 destroyed farms and displaced tens of thousands of poultry and other animals
Post-eruption landscape changes can strand wildlife populations by destroying habitat and food sources
Recovery of wildlife populations after major eruptions can take decades without active intervention

Welfare Considerations

Volcanic emergencies present extreme challenges for animal welfare response. The speed and unpredictability of eruptions, combined with dangerous conditions for rescue workers, means many animals cannot be helped in the acute phase. Livestock in the path of lava flows face a particularly grim welfare situation as evacuation windows close rapidly. Post-eruption, surviving animals face ash-contaminated food and water, respiratory disease, and landscape destruction. Emergency planning for high-risk volcanic zones should include livestock evacuation priorities, stockpiling of respiratory support supplies, and pre-agreement with veterinary services for mass euthanasia decisions when necessary.

What You Can Do

Support disaster relief organisations that include animal welfare in volcanic emergency response
Advocate for animal welfare to be included in volcanic risk management plans in hazard zones
If you keep animals in volcanic risk areas, develop and rehearse an evacuation plan
Support post-eruption habitat restoration programmes that accelerate wildlife recovery
