Magnitude 5.1 earthquake strikes south of Tonga
A magnitude 5.1 earthquake occurred south of Tonga on Monday, July 27, 2026, at 01:54:14 GMT. The United States Geological Survey (USGS) assigned a significance score of 400 out of 1000 to this event, indicating a moderate level of potential impact. The earthquake's shallow depth of 10 kilometers typically means that seismic energy is released closer to the surface.
As of now, no felt reports have been submitted to the USGS regarding this earthquake. This is not uncommon for earthquakes in regions with sparse populations or where public use of the reporting system may be limited. The significance score of 400 suggests that while the earthquake was notable, it is unlikely to have caused widespread severe damage or casualties based on general earthquake impact models for events of this magnitude and depth.
