The agency said on Twitter that the current volcano is “small” with “volcanic activity”, which has decreased “to some extent” in the area. According to IMO, with a lava area spanning less than one square kilometer, an eruption of about 500–700 meters long can occur.
The IMO said that despite this decrease in activity, lava flows are still a “local threat”.
Another tweet said, “People are not expected to cause much inconvenience due to gas pollution.
The IMO is monitoring gas emissions following Friday’s spectacular explosion, which led authorities to take civilians away from the major Reykzenesbrat highway.
Concern was expressed about the proximity of the volcano to Keflavik International Airport, the country’s main airport, which is just a 25-minute car ride from the peninsula.
The aviation color code for the airport was dropped from red to orange on Saturday due to the IMO predicting a minimum ash fall.
Iceland’s Department of Civil Protection and Emergency Management on Friday night advised people within several miles of the volcano to close their windows and stay indoors to avoid the effects of volcanic gas in the air.
The agency tweeted late Friday, “Volcanic gas pollution is expected to rise to lorlákshöfn and continue into the night. People are asked to close windows and stay. The status and amount of SO2 emissions from the eruption is being ascertained . “
IMO said in a tweet on Thursday, “This is somewhat less seismic activity than in previous mornings where the number has been around 1,000 earthquakes.”
