A powerful 7.8 magnitude earthquake struck off the coast of Fiji on Friday, 3.49AM local time — 101km (63 miles) east of the Fijian capital of Suva.
The quake struck at a depth of 606km (378 miles), according to the USGS.
Its depth meant only light shaking was recorded on the surface, and led the Pacific Tsunami Warning Centre to say, “Based on all available data, there is no tsunami threat because the earthquake is located too deep inside the Earth.”
Today’s Fijian earthquake follows an M8.2 which struck the Pacific island nation Aug 19.
And northern Japan continues to be rocked by M6+ quakes, with the latest popping off Sept 05, 27km East of Tomakomai, and registering M6.6 at a depth of 33.4km (21 miles).
The recent seismic uptick is likely attributed to the recent drop-off in solar activity, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
