RESIDENT in the Northwest felt the earth move this morning – as a Storm surge overhead caused a sonic boom.
Locals said they feared a “small earthquake” had enveloped the area, with some saying their homes “shaken” as a loud bang was heard.
But the British Geological Survey (BGS) said no tremors were recorded.
And then it was revealed that an explosion was heard as the storm went supersonic off the coast of Southport, Merseyside.
BAE Systems said the plane was part of a test flight with the RAF and apologized for any alarms caused.
Experts at BGS have revealed for the first time that the sound could be caused by an aircraft.
“We have signals that can be matched to an acoustic event,” one official said.
“British Aerospace confirmed that it had aircraft in the air at the time and two RAF aircraft, but cannot confirm at this time if which flew supersonic.”
Flightradar24, which monitors air traffic, showed an air force jet moving over the area at the time the sound was heard.
Several military aircraft were later seen flying in the direction of the North Sea, the website revealed.
Among those in the air around that time was a Boeing Poseidon MRA1 (P-8A), which flew over Guernsey and the English Channel after taking off from Inverness in Scotland, reports Plymouth Live.
The aircraft is a multifunctional maritime patrol vessel equipped with sensors and weapons systems for anti-submarine warfare. In addition, it is also used in surveillance and search and rescue missions.
It was also seen in South Devon and the Torbay area before heading towards Wales.
However, the mystery was solved this afternoon when the BAE confirmed the Storm was active in an offshore area.
They added that the sound could have been caused by “climatic conditions”.
TYPHOON GO SUPERSONIC
The jet is part of the Typhoon development programme, part of the UK’s national security programme.
Its call sign is Apollo 11, and it is used for quick response alerts. That could include potential threats to UK airspace.
The military has since confirmed its jets are not supersonic.
Inhabitants of Merseyside, Greater Manchester, Cheshire and Lancashire around 11 am.
A man living in Southport told echoes of Liverpool: “There was a big bang and the whole house shook violently.
“We went upstairs to look for a wardrobe or something that had been dropped, but we couldn’t find anything.
“When we saw other people talking about it on Facebook we thought it might be cracked, but then I saw a jet flying around Southport at the same time so now I wonder if is it a sonic explosion or not.”
Others in the area feared they had experienced a minor earthquake, the newspaper reported.
“Has there been a small earthquake? My house and windows are shaking,” one woman posted.
‘Definitely sounds and feels like two electrical pulses just before 11am,’ said another resident.
“The roof of the factory shook and rumbled deeply. It seemed the door inside the house was also moving.”
A third said: “I wonder what the hell it is, sounds like someone kicked in the door.”
It comes amid fears Europe is only a few hours away All-out war in Ukraine.
Russia has more than 100,000 troops concentrated near the border with neighboring Eastern European countries.
The US intelligence agency predicts that the heads of the Kremlin will order an attack on Ukraine at 1 a.m. local time tomorrow.
It means yes more military activity in the skies over Great Britain, although the Government said that British forces would not be sent to fight.
What is sonic boom?
The boom sound is the noise generated by the shock wave when an object moves faster than the speed of sound.
They sound like a loud bang or thunder.
The speed of sound, known as Mach 1 for aircraft, is approximately 767mph at sea level.
Curiously, the noise of a sonic boom is not heard in all directions from the object and is not heard only at the moment when the object passes the speed of sound.
The boom is a continuous effect produced while the vehicle is traveling at supersonic speeds.
