Magnitude 5.5 earthquake — Levuka, Fiji
A magnitude 5.5 earthquake struck near Levuka, Fiji at a depth of about 642 km. Details, shaking intensity and any tsunami information are on the USGS event page.
Explained simply
Fiji lies in the South Pacific, where the Pacific Plate meets several other large sections of the Earth’s crust. Movement in this region causes frequent earthquakes, including some deep below the surface.
Levuka is a town on the island of Ovalau and was once Fiji’s capital. The US Geological Survey records earthquake locations and measurements; the reported depth is relevant because deep earthquakes usually affect the surface differently from shallow ones.
