Boom theory busted as 'tremor' revealed
THE mystery of the strange tremor which reverberated throughout the region on Wednesday night has been solved.
Speculation on a "small earthquake" and "sonic boom" turned out to be RAAF jet training at the base in Amberley, with F/A-18F Super Hornets undertaking essential "intercept" training
Mt Marshall resident Jackie Robertson said she felt the tremor throughout her house just before 8pm.
"The windows on the western side of the home rattled quite significantly and I definitely felt something," she said.
"At first I thought one of the trees had come down."
Venturing out to the backyard to try to find the source, Jackie said her neighbours were also out scouring the area with their torches.
"We thought there had definitely been an explosion somewhere... we were just waiting for the sirens to go off."
Resident posts on the Daily News' Facebook page said the boom was also felt as far out as Killarney, Maryvale and Freestone.
An RAAF representative said the aircraft training was louder than anticipated.
"The Air Force is doing everything it can to reduce noise impacts on communities, whilst balancing essential operational and training requirements for Australia's security," the representative said.
When Jackie learnt the boom was from the jets, she said she didn't mind the noise.
"At the end of the day they've got to practice.
"No one is going to give us any warning if they come to invade."
A RAAF spokesperson said the Amberley western airspace would be used for training today as well, with the flying expected to be complete around 5pm.
"No one can predict when or where Air Force will need to respond, so our pilots and crews need experience in a range of environments.
"Although some training is conducted using flying simulators, nothing replaces actual experience for our pilots and crews."
