KUALA LUMPUR — A powerful earthquake with a magnitude of 6.5 struck offshore from the west coast of North Sumatra, Indonesia, on Tuesday at approximately 12.56pm local time, with its effects felt as distant tremors across northern Peninsular Malaysia.
According to the Malaysian Meteorological Department (MetMalaysia), seismic activity was recorded at geographic coordinates 2.0 degrees North and 96.5 degrees East, with the quake’s focus at a relatively shallow depth of about 10 kilometres beneath the ocean floor. The epicentre was located around 112 kilometres southeast of Simeulue, Indonesia — an island region off Sumatra’s western coast.
The tremors were sensed across several northern states of Malaysia, including Kedah, Penang and Perlis, where some residents felt slight shaking and vibration in the early afternoon. These seismic waves travelled over long distances from the quake’s epicentre, underlining the impact that offshore earthquakes can have even across maritime borders.
Despite the strength of the quake, MetMalaysia emphasised that there is currently no tsunami threat to Malaysia, assuring the public that the seismic event does not appear to have triggered hazardous sea conditions near Malaysian waters. This is consistent with rapid seismic and ocean monitoring protocols that assess the likelihood of secondary effects such as large waves after offshore tremors.
In its public advisory, MetMalaysia also invited individuals who felt the tremors to complete an online survey form to help scientists and authorities gather data on the earthquake’s perceived intensity and local impacts. Such public feedback assists seismologists in refining intensity maps and improving future preparedness and response strategies for similar events.
While there were no immediate reports of damage or injury in Malaysia following the quake, the unusual sensation of shaking reminded many residents in the affected states of Malaysia’s geological proximity to one of the world’s most active seismic regions. Indonesia, particularly the Sumatra region, lies along the Pacific Ring of Fire, an arc of fault lines and tectonic boundaries that is frequently the source of earthquakes ranging from moderate to severe intensity.
Local authorities have not issued any alerts or warnings beyond the survey request, and normal activities continued after initial tremors subsided. Nonetheless, experts emphasise ongoing public awareness, encouraging residents to stay informed about earthquake preparedness — particularly in regions that, while not typically high‑risk, can still feel the effects of powerful offshore seismic activity
