Are we better at noticing/recording these small earthquakes or are they increasing in regularity?

Just for the record, a smaller, nearby one a few seconds earlier

It might just be me with more time on my hands since I retired and an RSS feed of the BGS site.

Well thank you!

Let's not forget Snatcher Pot. Well worth a visit.

Or is the news of such events happening easier to broadcast?

 

[Lankyman]

Are there known faults at this location? Are they visible as surface features?

 

[alanw]

No faults shown on this map: https://largeimages.bgs.ac.uk/iip/mapsportal.html?id=1001529 (the area of interest is at the bottom of the map, around 88)

Nothing obvious on the LIDAR:

1.1 magnitude is a very small quake, somewhere about the same energy release as a Transit sized van crashing from motorway speed. I wouldn't expect any effect 10km away even if that 10km is vertical.

There are old faults almost everywhere, an event as small as that wouldn't necessarily be on a known or recently active fault.
