An earthquake of magnitude 4.4 occurred only 8 minutes ago 68 km southwest of Wellington, New Zealand, New Zealand's Earthquake Commission and Geological Survey (GeoNet) reported.
The quake hit at a very shallow depth of 9.5 km beneath the epicenter near Wellington, Wellington City, New Zealand, in the evening on Wednesday, June 22nd, 2022, at 8:16 pm local time. 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.3 earthquake.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Seddon (pop. 510) located 17 km from the epicenter, and Blenheim (pop. 26,600) 36 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Wellington (pop. 381,900) located 68 km from the epicenter, Wainuiomata (pop. 19,400) 80 km away, Lower Hutt (pop. 101,200) 82 km away, Porirua (pop. 50,900) 85 km away, Upper Hutt (pop. 38,400) 96 km away, Nelson (pop. 59,200) 96 km away, and Stoke (pop. 19,800) 97 km away.
