A magnitude 5.8 shallow earthquake struck 112 km NE of Hihifo, Tonga, amid a week-long seismic swarm including a M6.3 event, highlighting the relentless tectonic forces of the Tonga-Kermadec subduction zone.
A shallow magnitude 5.9 earthquake struck off Tonga’s northern islands at just 10 km depth, marking the ninth tremor in a week-long swarm along the volatile Tonga-Kermadec subduction zone near the site of the deadly 2009 M8.1 Samoa earthquake.
A rare magnitude 5.2 earthquake struck 501 kilometers beneath the Pacific Ocean near Fiji, just 69 km from the epicenter of the 2018 M8.2 megaquake—one of the deepest significant tremors ever recorded.
A shallow magnitude 5.6 earthquake struck 136 km northeast of Hihifo, Tonga, at a depth of 10km, rattling a region historically active with major seismic events including the deadly 2009 Samoa tsunami.
A shallow magnitude 6.3 earthquake struck just 35 km from the 2009 Samoa tsunami epicenter at only 10 km depth, capping a week-long seismic swarm in the Tonga-Kermadec subduction zone.
A shallow magnitude 6.2 earthquake struck just 57 kilometers from the catastrophic 2009 Samoa earthquake epicenter, raising immediate concerns about structural damage across the islands due to its extremely shallow 10-kilometer depth.
