I grew up in Northern England and I can assure readers that this is not prime earthquake country! What’s going on here?

Could this be fracking related perhaps? Or is the “underground rumble” something other than a regular seismic event. Certainly very noteworthy.

GRIMSBY,NE LINCOLNSHIRE
FELT NE
“Felt widely in NE Lincolnshire, North Lincolnshire, Kingston-upon-Hull and East Riding of Yorkshire.
This is the largest earthquake in the area (within 50km) since the magnitude 5.2 ML Markest Rasen event on 27 February 2008, which was felt throughout England and Wales. This is a region that has experienced a few earthquakes of this size, and larger, in the historical past. In 1703, a magnitude 4.2 event occurred near Hull, in 1750 a magnitude)4.7 event occurred in the Southern North Sea (approximately 20 km offshore Mablethorpe) and in 1954, a magnitude 4.2 event occurred near Bridlington.”
