A magnitude 6.2 earthquake struck south of Tonga late last night, prompting initial concerns but ultimately resulting in no tsunami threat to the island nation.
The tremor occurred at 11.49 pm local time on May 25, 2025, with its epicentre 180 kilometres south of Eua and 204 kilometres south of Tongatapu.
The quake originated at a depth of 71 kilometres, according to the Tonga Meteorological Service.
The National Tsunami Warning Centre quickly issued a “No Threat Advisory,” assuring residents that the seismic activity was unlikely to generate a tsunami.
“Based on preliminary analysis, a tsunami wave is unlikely to affect Tonga,” the advisory stated.
The message, authorised by the Tonga Meteorological Service, emphasised that only official warnings from their office should be considered definitive.
Residents in Tongatapu and ‘Eua reported feeling the earthquake, but no damage or injuries have been reported so far.
The National Emergency Operation Centre (NEOC) remains inactive, with normal contact procedures in place for any further inquiries.
Authorities noted that the earthquake’s magnitude is provisional and may be adjusted as additional seismic data becomes available.
This is the final update unless significant changes occur.
