Officials have advised against hiking by and around the volcano because of the risk of breathing in "a high level of dangerous, volcanic gases."
It has been reported that the explosion did not affect air traffic negatively.
The volcano, which is located in a valley near the Litli-Hrutur mountains, is also located nearby Keflavik Airport, which is 30 kilometers away from the capital of Iceland, Reykjavik, and also is where the international flights take place.
Fagradalsfjall did not cause any financial damage or any cancellation of flights, despite having erupted 2 times in the last 2 years.
