The epicenter, with a depth of 215.194 km, was initially determined to be at 18.4566 degrees south latitude and 175.199 degrees west longitude.

The magnitude 6.1 quake was centered off the east coast of Chiba Peninsula at a depth of 44.5 kilometers (28 miles), the U.S. Geological Survey said.
Strong shaking was reported in Chiba and Ibaraki prefectures, but the USGS said there was little chance of serious damage or fatalities.
Kyodo News service said no problems were reported at the Tokai No. 2 nuclear power plant in Ibaraki.
There was no immediate word on whether were any injuries or damage in the nearby areas, which are not densely populated.
The USGS said the quake was centered about 41 kilometers (25 miles) northeast of Puerto Obaldia, Panama. The epicenter was at a depth of 10 kilometers (6 miles). An aftershock with a magnitude of 4.9 followed about 10 minutes after the original quake.
The quake hit at a shallow depth of 10 km beneath the epicenter near Kirakira, Nakumwe, Makira-Ulawa Province, Solomon Islands, early morning on Monday, May 22nd, 2023, at 2:45 am 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.
A second report was later issued by France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 6.0 earthquake. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 6.2.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Kirakira (pop. 1,100) located 65 km from the epicenter, the quake should have been felt as light shaking.
The epicenter, with a depth of 10.0 km, was initially determined to be at 43.4362 degrees south latitude and 39.3676 degrees east longitude.
The epicentre was 35 kilometres (22 miles) deep and located about 300 kilometres (190 miles) east of the New Caledonian archipelago, it said. Any tsunami waves are expected to be less than 0.3 metres (one foot), the Pacific Tsunami Warning Center said in its latest update.
The waves may reach the Pacific islands of Fiji, Kiribati, Vanuatu and Wallis and Futuna, it said, after earlier issuing a warning for coasts within 300 kilometres (185 miles) of the epicentre.
On Friday, a 7.7-magnitude quake in the same area sent people scrambling for higher ground on several Pacific islands for fear of giant waves. A tsunami warning was lifted hours later.

The quake was detected some 340 kilometers east of Vao city in New Caledonia, a French Pacific territory, according to the U.S. Geological Survey.
In New Caledonia, the police had evacuated the coast and tsunami sirens had been activated.
Tsunami waves of one-to-three meters above tide are possible along some coastal areas of Vanuatu, according to the Honolulu-based Pacific Tsunami Warning Center.
The U.S. Geological Survey (USGS) said the magnitude 6.4 quake struck at a depth of 252 kilometers (156.6 miles) and its epicenter was some 2 kilometers southeast of the municipality of Canilla, Guatemala.
Guatemala's natural disaster agency said there were no immediate reports of damage, while the civil protection authorities of the southern Mexican state of Chiapas said there were no injuries or damage to property.
Neighboring El Salvador said on Twitter there was no risk of a tsunami from the quake.
