Magnitude 4.9 Quake Hits Lower North Island

WELLINGTON — A moderate magnitude 4.9 earthquake struck off the west coast of the lower North Island early Saturday morning, triggering more than 21,000 felt reports and rattling households from the Central Plateau to the top of the South Island.

According to geological monitoring network GeoNet, the tremor hit at 6:34 AM. Its epicenter was located approximately 30 kilometres northwest of Paraparaumu at a shallow depth of 26 kilometres. Residents across the region reported sharp pre-dawn shaking, with many describing a rolling motion accompanied by an audible rumbling sound prior to the primary wave.

Regional Impact and Felt Intensity

The tremor produced widespread moderate shaking across the Wellington region, the Kāpiti Coast, the Wairarapa, and parts of Marlborough. Thousands of citizens took to digital platforms to log their experiences, making it one of the largest public response tallies for a domestic seismic event in recent months.

Seismologists noted that the distinct primary and secondary wave arrivals contributed to a longer, rolling sensation that heightened public awareness across densely populated urban sectors. Emergency management agencies confirmed that no major structural damage or infrastructure failures had been reported immediately following the event, though municipal monitoring teams continued routine structural assessments across critical transit corridors.

According to GeoNet monitoring logs and official civil defense briefings:

• Magnitude & Depth: Measured at magnitude 4.9 originating at a depth of 26 kilometres.

• Epicenter Location: Approximately 30 kilometres north-west of Paraparaumu.

• Public Response: Over 21,000 felt reports logged across the lower North Island and upper South Island.

• Damage Assessment: Zero major infrastructure disruptions or structural damages recorded by midday Saturday.
