Leighton Buzzard has been hit by two aftershocks in the space of a few hours - taking the total number of earthquakes felt in the area over the last two weeks to four.
A magnitude 2.1 event struck at 1.39pm on Tuesday afternoon, just over four hours after a 3.0 tremor was felt in the Bedfordshire town at 9.32am.
Geologists said they were likely to be aftershocks of the first quake felt in the area on 8 September.
"There's obviously been some stress been building up in that particular area and we've had the initial earthquake," said Glenn Ford, a seismologist with the British Geological Survey (BGS). "It's maybe just still rebalancing the stress regime in that particular part of the world and we're getting these little aftershocks occurring as well."
The 8 September tremor was magnitude 3.5 and the first aftershock five days later measured 2.1.
According to the BGS, residents said Tuesday's first tremor "only lasted a couple of seconds" and that they "felt a single jolt, a bit like being in a car that has done an emergency stop".
