There were also some afterchosks in the area - one of which was at 15:30! MY friend who lives in Skopelos is the one who informed me after looking it up following them feeling a tremor at that time.

Is UTC (or your time) as this refers to of 1:21 (assuming my computer is picking up your time as the time in the UK) then the time in Greece at that time would be 3:21pm which is when we were landing in Volos
