Leighton Buzzard is hit by third earthquake in two weeks as tremor rattles homes
[ad_1]
A Bedfordshire town has been hit by an earthquake – the third tremor in two weeks.
The British Geological Survey (BGS) say the 3.0 magnitude earthquake was centered around the town of Leighton Buzzard.
It comes just weeks after a 3.5 quake struck the same town, on September 8.
Another tremor, which hit at 11.20pm on Sunday, September 13, was measured by the BGS at magnitude 2.1.
It is thought to have been an aftershock from the quake that was felt on September 8.
The latest tremor is said to have been around six miles deep and slightly to the north of the town, according to the BGS, who believe the series of quakes to be ‘naturally occurring’.
Independent scientific organization, the European-Mediterranean Seismological Centre (EMSC), report the quake to be around 3.1 magnitude and slightly more to the south, near to the Hertfordshire village of Tring.
According to the BGS, the quake took place around 8.30am today, though twitter users in Leighton Buzzard reported feeling the latest shaking shortly after 9.30am this morning.
One said: ‘Was that another earthquake in Leighton Buzzard? Anyone else feel that?’

A tweet posted this morning by the BGS said: ‘We are getting reports of an earthquake in the Leighton Buzzard area this morning.
‘We are currently investigating this and will update you as soon as we can.’
In a follow up tweet, the BGS said: ‘We’re receiving reports about the earthquake, which followed previous events in the same area on September 8 and 13, with magnitudes 3.5 and 2.1.
‘Reports describe ‘only lasted a couple of seconds’ and ‘just felt a single jolt, a bit like being in a car that has done an emergency stop!’
One Twitter user, Dina Gower, said: ‘Felt it about 9:34am in Leighton Buzzard – house shook and windows rattled but not as strong as on September 8.’
Another, James Emm, said: ‘Shook our house in Linslade / Leighton buzzard at about 9.34ish for a moment.
‘This felt like like more of a shake than the first one which felt more like an explosion.
‘Would day slightly weaker too or just not on top of the epicenter as much this time.’
Another, Joe Reggelt, added: ‘Conservatory rattled and the similar ‘explosion’ sound as September 8 event but not as loud.’
The series of tremors in the town could be part of a ‘swarm’ of earthquakes, the BGS has told Mirror Online.
If that is the case, it could be similar to a series of 34 earthquakes known as the ‘Surrey swarm’, which took place between April 2018 and May 2019.
At the time, neighbours blamed oil wells a few miles away in Horse Hill and Brockham.
However, a study by Imperial College London, the University of Bristol and the British Geological Survey (BGS) concluded the earthquakes were natural.
Speaking about the Leighton Buzzard tremors, Glenn Ford, a seismologist with the BGS, said: ‘What we’re seeing here is a small aftershock from that earthquake (on September 8).’
Mr Ford said it was ‘typical behaviour’ which had been seen in different areas of the UK ‘on many occasions’.

He added: ‘There’s obviously been some stress been building up in that particular area and we’ve had the initial earthquake.
‘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.
‘It probably will settle down soon but could we get another one? We certainly could, but when it could happen, we don’t know.’
HOW ARE EARTHQUAKES MEASURED?
Earthquakes are detected by tracking the size, or magnitude, and intensity of the shock waves they produce, known as seismic waves.
The magnitude of an earthquake differs from its intensity.
The magnitude of an earthquake refers to the measurement of energy released where the earthquake originated.
Magnitude is calculated based on measurements on seismographs.
The intensity of an earthquake refers to how strong the shaking that is produced by the sensation is.
A 5.3 magnitude earthquake hit the Channel Islands off the coast of southern California on Thursday at 10.30am
According to the United States Geological Survey, ‘intensity is determined from the effects on people, human structures and the natural environment’.
Earthquakes originate below the surface of the earth in a region called the hypocenter.
During an earthquake, one part of a seismograph remains stationary and one part moves with the earth’s surface.
The earthquake is then measured by the difference in the positions of the still and moving parts of the seismograph.
