An earthquake of magnitude 4.3 occurred early morning on Wednesday 27 January 2021 at 6:29 am local time near Palmerston North, Palmerston North City, Manawatu-Wanganui, New Zealand, as reported by New Zealand's Earthquake Commission and Geological Survey (GeoNet).
According to preliminary data, the quake was located at a shallow depth of 29.9 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
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 Foxton (pop. 4,800) located 27 km from the epicenter, and Levin (pop. 19,800) 34 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Paraparaumu (pop. 25,300) located 54 km from the epicenter, Palmerston North (pop. 76,000) 55 km away, Wanganui (pop. 40,300) 56 km away, Porirua (pop. 50,900) 78 km away, Upper Hutt (pop. 38,400) 78 km away, Lower Hutt (pop. 101,200) 87 km away, and Wellington (pop. 381,900) 96 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
