Series of Large Earthquakes Strike Vanuatu

At approximately 13:34:41 UTC on Thursday, February 2nd, an earthquake based on water struck at a depth of 23.1 km (14.4 miles) in the Vanuatu region, 124 km (77 miles) W of Port-Vila, Efate, Vanuatu, and 251 km (155 miles) S of Luganville, Espiritu Santo, Vanuatu. Coords: 17.766°S, 167.134°E

The largest recorded initial quake was a 4.8 magnitude at approximately 10:44:08 UTC, at a depth of 147.2 km (91.5 miles). Following the 7.1 a series of large aftershocks began and still continue to be recorded in the area. After the 7.1 struck, a 4.9 and 5.3 hit the area within 25 minutes, and from 16:00 to 22:00, a 5.0, 5.5, 5.2, 4.9, 5.1, 5.1 and 4.8 also hit the area. On February 3rd, at approximately 03:46:23, a 6.0 magnitude aftershock it appears, struck the area as well, at a depth of 21.7 km (13.5 miles), followed by a 5.4 at 04:33:09 and a 5.7 quake at 06:01:42.

United States Geological Survey – The main event has been reviewed by a seismologist and confirmed, at present, to be a 7.1 magnitude earthquake at a depth of 23.1 km (14.4 miles). The European Mediterranean Seismology Agency is in agreeance with the main earthquake parameters provided by the USGS, except for depth, which is recorded to have been at 10 km.

Based on all available data a destructive Pacific-wide tsunami is not expected and there is no tsunami threat for Hawaii


The region of Vanuatu is on the so-called Pacific Ring of Fire, an arc of unstable fault lines circling the Pacific Basin that is prone to frequent and large earthquakes. In August of 2011, two powerful earthquakes measuring 7.1 and 7.4 mag on the Richter scale struck about 63 kilometers south-southwest of Port-Vila, on the south coast of the island of Efate.
