A 6.8-magnitude earthquake struck off the coast of New Zealand’s main South Island on Tuesday, according to the US Geological Survey, which placed the epicenter at a depth of 10 kilometers and about 100 kilometers from the South Island.
The Saudi Press Agency reported the quake in a brief bulletin dated March 25, 2025, citing the US Geological Survey for the magnitude, depth and distance figures. SPA also reported that there have been no reports of casualties or damage so far.
The South Island is New Zealand’s larger landmass by area and its southernmost major island, separated from the North Island by the Cook Strait. A quake centered roughly 100 kilometers offshore therefore sits at a distance from the island’s populated centers, though the bulletin did not specify which coastal areas, towns or cities lie closest to the epicenter.
Depth is one of the variables seismologists use when assessing how a quake is felt at the surface. The US Geological Survey put this event at 10 kilometers, a figure SPA carried without further interpretation. What does a 10-kilometer depth mean for how the shaking is experienced on land?
Magnitude, too, is a measure of the size of the event at its source rather than a direct measure of damage. The 6.8 figure is the only magnitude SPA reported, and it is attributed to the US Geological Survey rather than to New Zealand authorities. How often do offshore quakes of this size pass without any reported consequences?
SPA’s bulletin was issued from Wellington, New Zealand’s capital, which sits at the southern end of the North Island. The dateline on the report is March 25, 2025, and the agency stamped the item with a local time of 10:34 and a GMT time of 07:34, a three-hour difference consistent with the timing conventions used in the bulletin itself.
No casualties and no damage had been reported at the time the bulletin was issued. That absence of reports is the second of the two factual pillars in the SPA item, alongside the US Geological Survey’s magnitude, depth and distance figures. Does the lack of early reports always hold as more information arrives?
The bulletin did not name any agency or authority that might issue further assessments, and it did not carry a statement from New Zealand officials, emergency services or any monitoring body. It also did not say whether a tsunami warning or advisory was issued, whether one was considered, or whether any coastal precautions were taken.
What the SPA text does provide is a compact set of measurements: a magnitude of 6.8, a depth of 10 kilometers, a distance of about 100 kilometers from the South Island, and a location off the coast of that island. Each of those figures is attributed to the US Geological Survey. Which of these numbers matters most to the people living nearest the epicenter?
The item carries no information on aftershocks, no count of them, and no indication of whether any were expected. It does not describe the tectonic setting of the region, the fault involved, or the history of seismicity along that coast. It does not say what time the quake occurred beyond the bulletin’s own dateline and time stamps.
SPA’s report also does not include the population of the affected area, the names of any nearby settlements, or the distance from the epicenter to any specific town or city. The only geographic anchor given is the South Island itself, described as New Zealand’s main South Island, with the epicenter about 100 kilometers from it.
Readers following the story may wonder how an offshore location is determined at all. The bulletin does not explain the method behind the US Geological Survey’s coordinates, nor does it give latitude and longitude. Why do some quake reports include precise coordinates while others, like this one, do not?
The absence of casualty and damage reports is stated as a fact as of the bulletin’s issue time, not as a forecast. SPA did not say when that assessment was last updated, how it was gathered, or from whom. It simply reported that there have been no reports so far.
New Zealand’s South Island coast faces the Tasman Sea to the west and the Pacific Ocean to the south and east. The bulletin does not say which side of the island the epicenter lay on, only that it was off the coast and about 100 kilometers from the island. Does the direction of an offshore epicenter change what coastal communities should expect?
The SPA item runs to four short lines of substance: the magnitude and location, the US Geological Survey’s depth and distance figures, the absence of casualty and damage reports, and the agency’s sign-off. It is a wire-style bulletin rather than a developed report, and it does not attempt to place the event in a wider context.
That means several questions a reader might reasonably ask are left open by the source itself. Was the quake felt on land? Did any transport, power or communications infrastructure experience disruption? Were schools, ports or airports affected? The bulletin answers none of these, and this article does not supply answers the source did not provide.
What the source does establish is a sequence of attributed facts: an earthquake measuring 6.8, off the coast of New Zealand’s main South Island, on March 25, 2025, at a depth of 10 kilometers and about 100 kilometers from the island, per the US Geological Survey, with no reports of casualties or damage so far. Everything beyond that remains outside the bulletin.
SPA issued the item from Wellington and closed it with its standard agency mark. The time stamps show 10:34 local time and 07:34 GMT. The reference number carried on the bulletin is 0021. No further SPA material on the earthquake was included in the source text provided.
For readers in the Kingdom and elsewhere, the report is a reminder of how quickly seismic events are recorded and distributed across agencies, and how much of the picture — damage, casualties, warnings, aftershocks — typically arrives after the first bulletin rather than within it. What would you want to know first if a quake of this size were reported near a coast you knew?
What magnitude and location did the US Geological Survey report for the New Zealand earthquake? According to the US Geological Survey, cited by SPA, the earthquake measured 6.8 and occurred off the coast of New Zealand’s main South Island. The epicenter was located about 100 kilometers from the South Island. SPA reported the event in a bulletin dated March 25, 2025, issued from Wellington. The bulletin gave the magnitude and the distance from the island as the two key locational facts, without naming any specific town, city or coastal region near the epicenter.
At what depth did the earthquake occur, and what distance was given from the South Island? The US Geological Survey placed the earthquake at a depth of 10 kilometers, according to the SPA bulletin. The same source put the epicenter about 100 kilometers from the South Island. Those two figures — depth and distance — were the only measurements of the quake’s position that SPA carried. The bulletin did not provide latitude and longitude coordinates, nor did it specify which side of the island the epicenter lay on.
Were there any casualties or damage reported after the earthquake? SPA reported that there have been no reports of casualties or damage so far at the time the bulletin was issued. The item did not say when that assessment was last updated or how it was gathered. It also did not name any authority that might issue further assessments. The absence of reports was stated as a fact as of the bulletin’s issue time, not as a forecast for what might follow.
When and from where was the SPA bulletin on the earthquake issued? The SPA bulletin was dated March 25, 2025, and issued from Wellington, New Zealand’s capital. It carried time stamps of 10:34 local time and 07:34 GMT, a three-hour difference. The bulletin was a short wire-style item running to four lines of substance, closing with the agency’s standard sign-off and the reference number 0021. It did not include statements from New Zealand officials or emergency services.
What details did the SPA report not include about the earthquake? The SPA bulletin did not say whether a tsunami warning or advisory was issued, whether any coastal precautions were taken, or whether aftershocks occurred or were expected. It did not name any nearby settlements, give the population of the affected area, or describe the tectonic setting or fault involved. It also did not say whether the quake was felt on land or whether transport, power or communications infrastructure experienced any disruption.
