The First of the Earthquake Tremor hits at the Snowdonia Mountain range. I actually live on the rim of this mountain range.
Quake was close to the Aernig Fawr Volcanic Known area. Volcano classed as Extinct.
The Second Earthquake Tremor in Scotland area. The Scottish mountains and also across the way in Ireland are also marked as Extinct Volcanoes.
Here is the Extinct Volcanoes known to the "Experts"..
Just a Heads up. Usually Earthquakes around Volcanoes signals activity. My view is we have had little activity so this is not a cause for concern right now.
