Seismic swarm at Katla
An intense seismic swarm is ongoing since yesterday morning 29 September at Katla volcano. An intense pulse started today at 12:02 (30 September) with several earthquakes around magnitude 3 or larger. No seismic tremor has been detected. Due to the unusually high level of unrest at the Katla volcano we rise the aviation colour code from green to yellow. The volcano continues to be monitored closely.
Aviation colour code yellow means that the volcano is experiencing signs of elevated unrest above known background levels. More on colour codes on our website.
