2.8 million tonnes less CO2 due to flight bans
This reduction is significant in the context of climate change and air quality.
How much did the Jakulhaup river exceed its capacity?
Over 100 times its capacity
This extreme overflow illustrates the severity of the flooding caused by volcanic activity.
What was the impact of fluoride deposits on grazing land?

Diggers were in position to dam rivers and texts were sent to locals with a 30-minute warning
These actions helped mitigate immediate impacts and ensure public safety.
What immediate responses were enacted during the environmental crisis?
700 locals were evacuated and 100,000 European flights cancelled during a 6-day ban
Evacuations and flight cancellations were crucial for public safety and managing the crisis.
What long-term response did the Icelandic government implement?
Rebuilt river banks higher than before
This proactive measure aimed to prevent future flooding and protect infrastructure.
Fill in the blank: The Jakulhaup river was over _______ times its capacity.
100
