The 8.2 magnitude earthquake was felt throughout the country, including in Whanganui.

Fields walked to Whanganui the next day and recalled the landscape was full of cracks, with sand and mud brought up from below. In a letter to his sister, surveyor HC Fields wrote he had just gone to bed in Waitōtara and was reflecting on a day of strange weather and odd-acting animals when his house began shaking. When it stopped he went to check on his neighbours, but the aftershocks were too strong and he was thrown from the path, unable to stand. Mr Bates was relaxing in the Commercial Hotel when the building started shaking. The next day, Bates described the change in landscape. The whole region was governed by a provincial government until the introduction of local councils and a central government in 1876.

Magnitude-5.0 offshore earthquake occurs near Shortland Island, in ... (Crisis24)

Magnitude-5.0 offshore earthquake occurs near Shortland Island, in Soloman Sea, at 07:13 Jan. 23. No immediate reports of damage.

Utility outages are possible, particularly near the earthquake's epicenter. The tremor occurred at a depth of about 117 km (73 miles), and light shaking may have been felt throughout the northwestern Solomon Islands and Bougainville Province, Papua New Guinea. A magnitude-5.0 earthquake occurred in the Solomon Sea, near Shortland Island at around 07:13 Jan.

Silent enigma: the '7.0 earthquake' that Kiwis never felt this month (New Zealand Herald)

Slow-motion quakes unfolding beneath NZ just released the equivalent energy of a 7.0 jolt.

“So, this latest sequence of slow slip events is well-timed for us to learn far more than we ever have about New Zealand’s slow-motion earthquakes.” The events come several months after a large slow slip event near Hawke’s Bay last year, on a portion of the fault sandwiched between where the latest events were occurring. “So this shows us that these slow slip events can accommodate and release a lot of pent-up energy from the tectonic plates in a slow way, rather than in earthquakes, which is a good thing.” Onshore, there was a large temporary network of seismometers deployed around southern Hawke’s Bay region to detect quakes during slow slip events, as part of a new Marsden Fund-supported project. Altogether, Wallace said the amount of slow slip movement around the boundary during the last month roughly equated to the energy release of a 7.0 tremor. “This is because the slow slip event produces changes in stress in the earth’s crust, causing some nearby faults to rupture in small earthquakes.”

New Zealand's largest fault zone just released the equivalent energy of a magnitude 7.0 earthquake, through slow-burning "silent" events linked to recent ...

Recent programmes that have deployed dozens of seafloor sensors along the subduction zone, and drawing around $70m in funding, have turned New Zealand into something of a global slow slip event observatory. The events come several months after a large slow slip event near Hawke's Bay last year, on a portion of the fault sandwiched between where the latest events were occurring. "So this shows us that these slow slip events can accommodate and release a lot of pent up energy from the tectonic plates in a slow way, rather than in earthquakes, which is a good thing." Altogether, the amount of slow slip movement around the boundary during the last month roughly equated to the energy release of a 7.0 tremor, Wallace said. "This is because the slow slip event produces changes in stress in the earth's crust, causing some nearby faults to rupture in small earthquakes." Events in the region, which tended to occur twice a decade and last one to two years, had previously driven up to 30cm of movement.
