A strong earthquake measuring magnitude 7.6 struck near Neiafu in Tonga on Tuesday, according to data released by the United States Geological Survey (USGS). The tremor occurred at a significant depth, reducing the likelihood of widespread surface damage.
The earthquake’s epicentre was located approximately 153 kilometres west of Neiafu, a key town in the Pacific island nation of Tonga. It struck at around 4:37 UTC at a depth of about 237.5 kilometres beneath the Earth’s surface.
Authorities have reported no immediate casualties or damage following the seismic event.
The Pacific Tsunami Warning Center (PTWC) confirmed that no tsunami alert was issued, as the depth of the earthquake meant it was unlikely to displace enough water to generate a tsunami.
This event follows another earthquake of magnitude 6.2 that struck the Hihifo region of Tonga just a day earlier, highlighting ongoing seismic activity in the region.
Separately, mild tremors were reported in Nepal on Monday, where a 4.1 magnitude earthquake affected the Sudurpaschim province. The epicentre was identified near Bajhang district, with tremors also felt in nearby areas including Bajura and Baitadi. No damage or casualties were reported there either.
Tonga, part of an archipelago of over 170 islands in the South Pacific, lies along the Pacific Ring of Fire — a region known for frequent seismic and volcanic activity. Similarly, Nepal is situated in a highly active tectonic zone, making both regions prone to recurring earthquakes.
Experts note that while deep earthquakes like the one in Tonga are less likely to cause severe surface destruction, continued monitoring is essential due to the region’s geological sensitivity.
Authorities in both regions continue to assess conditions and advise residents to remain alert while relying on official updates for accurate information.
