5.8-magnitude earthquake jolts North Sumatra region

The earthquake hit the North Sumatra region, according to data from the Malaysian Meteorological Department. The tremor, which registered 5.8 in magnitude, posed no risk of generating a tsunami that could impact Malaysian shores or waters.

The quake struck an area of Indonesia's western coast that sits along the Ring of Fire, a seismically active zone prone to significant tectonic activity. North Sumatra experiences frequent seismic events due to its proximity to major fault lines and the subduction zone where the Indo-Australian Plate meets the Eurasian Plate.

MetMalaysia's assessment indicated that the moderate-strength earthquake did not meet the threshold for generating dangerous tsunami waves. The agency continues to monitor seismic activity in the region and provides regular updates to relevant stakeholders and the public.
