Earthquake Tremors Felt in Phuket After 5.1-Magnitude Quake Near Sumatra

Residents in several parts of Phuket reported feeling light tremors on Wednesday morning after a 5.1-magnitude earthquake struck off the northern coast of Sumatra, Indonesia.

According to seismic data, the earthquake occurred at 11:18am local time at a depth of around 10 kilometres.

The epicentre was located approximately 381 kilometres southwest of Satun Province in southern Thailand.

In Talad Yai in Phuket Town, employees working on the fourth floor of a low-rise office building said they felt noticeable shaking, while ceiling lights and hanging fixtures swayed during the tremor.

In Patong, guests and staff staying on the eighth floor of a hotel also reported feeling the building move for about two seconds.

Authorities said there were no reports of injuries or property damage in Thailand. However, the earthquake caused concern among residents and visitors who experienced the brief shaking.

Northern Sumatra lies along the boundary of the Indo-Australian and Eurasian tectonic plates, making it one of the region’s most seismically active areas. Earthquakes originating in this zone are relatively common, and stronger tremors can occasionally be felt in southern Thai provinces, including Phuket and Satun.

Officials continue to monitor the situation. No tsunami warning has been issued.
