5.5 quake 29 Apr 3:58 pm (GMT +12)
An earthquake of magnitude 5.5 occurred only 7 minutes ago 127 km northeast of Ruatoria, New Zealand, New Zealand's Earthquake Commission and Geological Survey (GeoNet) reported.
The quake hit at a moderately shallow depth of 30.1 km beneath the epicenter near Ruatoria, Gisborne District, Gisborne, New Zealand, early afternoon on Thursday 29 April 2021 at 3:58 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.
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 Ruatoria (pop. 900) located 127 km from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
