4.9 quake 12 Feb 4:54 pm (GMT +13)
A intermediate magnitude 4.9 earthquake was reported in the afternoon near Wanganui, Wanganui District, Manawatu-Wanganui, New Zealand.
According to New Zealand's Earthquake Commission and Geological Survey (GeoNet), the quake hit on Friday 12 February 2021 at 4:54 pm local time at an intermediate depth of 119.8 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Patea (pop. 1,300) located 56 km from the epicenter, Hawera (pop. 11,100) 66 km away, Wanganui (pop. 40,300) 84 km away, and New Plymouth (pop. 49,200) 122 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you’re in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
