Magnitude 6.1 earthquake in the Solomon Islands

mmmmm

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.

7.1-magnitude earthquake strikes east of New Caledonia - 2nd major quake there in 24 hours - Mag. 6.5 aftershock also recorded

zzzzzzzzz
A 7.1-magnitude earthquake struck Saturday in the Pacific Ocean to the east of New Caledonia, the US Geological Survey said, a day after a major quake hit the same area.

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.

New Caledonia lifts tsunami warning after 7.7-magnitude quake

mmmmmmm
New Caledonia lifted its tsunami warning to citizens after a 7.7-magnitude earthquake struck on Friday in the Pacific Ocean southeast of the territory.

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.

Magnitude 6.4 earthquake shakes Guatemala and southern Mexico, no damage reported

nnnnnn
A strong earthquake struck Guatemala on Wednesday, shaking the Central American nation and parts of Southern Mexico, though the quake's deep hypocenter of more than 150 miles underneath the earth's surface seems to have averted damage.

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.

Magnitude 7.6 earthquake hits near Tonga, no tsunami warning is issued

mmmmm
An earthquake of magnitude 7.4 struck off Tonga on Thursday, United States Geological Survey said.

The quake was at a depth of 212 km (132 miles) and the epicenter was at a distance of 73km northwest of Hihifo, Tonga, the USGS reported.

Hihifo is the main village on the island of Niuatoputapu, north of Tonga's main group of islands.

The U.S. Tsunami Warning System said there was no tsunami warning.

Angie Pula Letuligasenoa was in her home in Iliili, near Pago Pago International Airport, when the 'rolling' earthquake struck.

A slew of earthquakes shook up the Salton Sea region of Southern California within 24 hours over the weekend, with the seismic activity reaching up to 4.5 in magnitude.

The first swarm began at 12:08 p.m. Saturday in the US-Mexico border town of Herber, with nearly 50 tremors shaking the area until 5:12 a.m. Sunday, the US Geological Survey reported. The Herber quakes reached up to 3.7 in magnitude and were felt by about 60 people.

The second swarm struck nearly 40 miles north, by the town of Niland, where more than 25 tremors then shook the southeast shore of the Salton Sea starting at 12.09 a.m. Sunday.

Those earthquakes lasted until 5:28 a.m. and reached a higher magnitude of 4.5, which was felt by about 30 people, UGS said.
