Gwent Police said it had received “multiple calls” overnight but it was “business as usual” for the force.
The BGS said the earthquake was 1.8 miles (3km) under the Earth’s surface.
“My whole bed shook,” Ms Humphreys tweeted. Others described it as a “scary” experience.

“I’m in Rhymney and felt the house shake, looked online to see if anyone else did.. and it was an earthquake in South Wales. I think I need a change of trousers,” tweeted @KrissOttley.
Helen Caswell added: “Our whole house shook in Rassau, Ebbw Vale and woke my husband up!! Really frightened us.”
“I thought some idiot had driven into my front door the way my room shook,” said Jack Hill, from Risca in Gwent, on Facebook.
Cath Willcox, from Cwm in Blaenau Gwent, told Sky News: “I felt the earthquake and was really concerned. It made our house shake, it was loud and the rumbling from it was clearly felt.
“We’re four to five miles from the epicentre of the earthquake.”
She said the whole village was affected, adding: “The village is in Cwm Ebbw Vale. An old mining village used to lots of action in the height of coal mining. This is not a wake up call we wanted.”
