Recent high seismic activity in Europe It seems that Europe and the Mediterranean Sea have had high seismic activity in last six months. Major events which I remember are:

2020 Aegean Sea earthquake, magnitude of 7.0  Mww
29 December 2020:  Petrinja, Croatia, magnitude 6.4 earthquake
Many Etna volcano eruptions
3 March 2021: Týrnavos, Greece  6.3  Mww
Many earthquakes in recent weeks in Iceland and an alert for volcanic eruption
Today (18 March 2021): 6.0 Mww earthquake in souther Mediterranean Sea, near Béjaïa, Algeria

What could this high seismic activity across Europe tell us?
There is a nice tracker for global earthquake activity at https://www.volcanodiscovery.com/earthquakes/global-seismic-activity-level.html, although it doesn't conveniently allow you to look at regional statistics, as opposed to global or national records.
At a global level there doesn't seem to be any particular increase in events , although in a quasi random series clustering in time and space isn't unexpected.
The perception that there might be an increase is probably a reflection of human and media behaviour; when one event occurs it heightens our interest and the likelihood of noticing other events. The media are far more likely to report a small earthquake occurring in the immediate aftermath of a large earthquake elsewhere in the world, than they would have if it had occurred in isolation.
