Magnitude 6.1 earthquake near 93 km NNE of Hihifo, Tonga Date: 2026-04-19 Time: 17:34:47 UTC Location: 🇹🇴 Tonga This quake occurred due to movement along the Tonga Trench, where the Pacific Plate subducts beneath the Indo-Australian Plate. The shallow depth suggests strong shaking near the epicenter. Expect strong shaking in nearby areas, but no tsunami warning h https://www.google.com/maps/@-15.1256,-173.6164,6z #Earthquake #Seismology #SeismoTrack #Tonga
