The earthquakes were analysed at Met Eireann's Seismic monitoring station at Valentia Observatory, Caherciveen, Co. Kerry.

The Seismology Station at Valentia is part of the Irish Seismic Network. From the analysis of the event the P wave took approximately 7 mins 41 seconds  to reach the Met Eireann facility at 12.31.03 UTC with the S wave occurring at 12.37.19 UTC.

This part of Iran is an active Seismic zone. Over the past 40 years, seven earthquakes of Magnitude 6 or greater have occurred within 300 km of these events.
