PETALING JAYA – According to the Bureau of Meteorology (MetMalaysia), the quake in Peninsular Malaysia may have been caused by the reactivation of an ancient fault line following a high-magnitude earthquake in Sumatra, Indonesia.
He said several areas such as Bukittinggi and Jerantut in Pahang and Kuala Pila in Negeri Sembilan are among those affected by these fault lines.
“Malaysia is located near two seismically active plate collision boundaries: the collision boundary between the Indo-Australian and Eurasian plates to the west and the Eurasian and Philippine Sea plates to the east,” said MetMalaysia. said.
“The tremors of high-magnitude earthquakes centered on these plates may have been felt in Malaysia. caused by an earthquake.”
Several Recent earthquakes from Indonesia Earthquakes reported and felt in Malaysia occurred on April 4 and 25 with magnitudes of 6.2 and 7 respectively.
According to MetMalaysia, localized earthquakes are possible in Sabah as fault lines within the state are still active.
“Earthquake occurrence in Malaysia is usually more concentrated in Sabah due to the presence of several active fault lines such as the Mensabang and Lobow-Lobow fault lines,” he added.
MetMalaysia said a 2017 study of active faults in Peninsular Malaysia also suggested that the Bukittinggi fault zone is considered an active fault and a potential source of future earthquakes. .
In addition, it became clear that areas other than the Bukittinggi fault, the Venus fault, and the Karak fault are also active.
Since 2017, Peninsular Malaysia has experienced mild earthquakes. Virtually all earthquakes recorded on the peninsula were less than magnitude 5.
“However, the recognition of active faults that exhibit active tectonic topography suggests that these faults have caused destructive earthquakes in the past and may cause similar tremors in the future,” said MetMalaysia. says.
A 2021 study by the Prince of Songkla University found that Peninsular Malaysia faces earthquake risk not only due to regional tectonics, but also due to local tectonics.
The authors of the study, Dr. Dony Adriansyah Nazaruddin and Dr. Helmut Duerrast, said:
