Authorities have yet to determine the cause behind the explosion-like noises and tremors reported across various parts of the district last week.
According to Perak Menteri Besar Datuk Seri Saarani Mohamad, police investigations are still underway due to the potential implications for state security.
“The inquiry is still in progress, but no definitive cause has been identified so far. As such, we’re not in a position to make any detailed comments. Once the police complete their investigation, the findings will be compiled into a report for the state government,” he said after launching the Malaysia Culinary World Cup 2025 at Bulatan Sultan Azlan Shah on Friday.
He added that this was not the first time such incidents had been experienced in Perak and Selangor, yet the origin of the disturbances remains elusive.
Meanwhile, the Perak branch of the Department of Minerals and Geoscience (JMG) has confirmed it is continuing geological surveys in the Ipoh area, though no conclusive evidence has emerged so far.
The department noted that similar unexplained booms have been recorded globally. Often described as originating from the sky, these sounds range from moderate to loud and can sometimes cause windows and building structures to shake.
Beyond Ipoh, such occurrences have also been reported in countries like Japan, the United States, Bangladesh, Belgium, Australia, the United Kingdom, Canada, Colombia, Finland, Vanuatu, Italy, Ireland, and Indonesia.
These unexplained sounds were previously documented in the years 2012, 2018, 2024, and most recently on 18 June in Ipoh.
Officials have ruled out several potential causes, including quarry blasts, bomb tests, and sonic booms from military jets. —June 27, 2025
