Another earthquake has been confirmed in Surrey - the latest in a series of tremors to be felt since April.
The 1.7 magnitude quake struck at about 05:00 BST just north of Russ Hill near Newdigate at a depth of 1km, the British Geological Survey (BGS) said.
It was picked up by two new seismic stations built last week to record the earth's movements in Surrey after the recent spate of tremors.
The quake was like "a weak thud" lasting a few seconds, the BGS said.
It is thought to be ninth tremor in the earthquake "swarm".
Dr Stephen Hicks, from Southampton University, tweeted: "Gotcha - captured at last! Another small felt earthquake in Surrey this morning recorded on our two new seismic monitoring stations just a few km away."
He said he also recorded the tremor using equipment in his living room, 20 miles away.
Dr Hicks told BBC Surrey the magnitude of the latest tremor was "at the lower end of the sequence that we've had so far".
"It shows this swam of earthquakes is continuing and will be closely monitored now we have the new stations.
"I don't think we're going to see any large earthquakes in this region, but they might continue to be felt as the sequence continues," he said.
