Earthquakes are common in Vanuatu, a low-lying archipelago of 320,000 people that straddles the seismic Ring of Fire, an arc of intense tectonic activity that stretches through Southeast Asia and ...
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes. It is about 40,000 km (25,000 mi) long [ 1 ] and up to about 500 km (310 mi) wide, [ 2 ] and surrounds most of the Pacific Ocean .
The majority of tectonic earthquakes originate in the Ring of Fire at depths not exceeding tens of kilometers. Earthquakes occurring at a depth of less than 70 km (43 mi) are classified as "shallow-focus" earthquakes, while those with a focal depth between 70 and 300 km (43 and 186 mi) are commonly termed "mid-focus" or "intermediate-depth ...
The USGS estimated that the earthquake could cause economic losses measuring between 1–10% of Vanuatu's GDP. [19] The United Nations Office for the Coordination of Humanitarian Affairs estimated that 116,000 people had been directly affected by the earthquake, [44] equivalent to a third of Vanuatu's population. [45] Among them were 14,000 ...
The state typically experiences between 10 and 20 earthquakes above magnitude 2.0 each year, said Andy Newman, a professor of geophysics at Georgia Tech. As for what’s behind the recent shakes ...

The 1949 Olympia earthquake was a damaging magnitude 6.7 intraslab earthquake that occurred at 52 km depth and caused eight deaths. Another notable intraslab earthquake in the Puget Sound region was the magnitude 6.8 2001 Nisqually earthquake. Intraslab earthquakes in Cascadia occur in areas where the subducting plate has high curvature. [13]
Multiple earthquakes are rattling Santorini, a volcanic island in Greece, prompting authorities to dispatch rescuers with tents, a sniffer dog and drones, and to shut schools on four islands.
