South Africa's Johannesburg Hit By Powerful Earthquake
The tremor struck at 2:38 am (0038 GMT) around 10 kilometres (six miles) below the surface, the USGS said.

Johannesburg: A 5.0-magnitude earthquake on Sunday struck near Johannesburg, shaking buildings across South Africa's most populous province, the Unites States Geological Survey reported.
The tremor struck at 2:38 am (0038 GMT) around 10 kilometres (six miles) below the surface, the USGS said.

Buildings shook across the province of Gauteng, where Johannesburg, the country's largest city and commercial hub, is located.

Residents across the province felt the tremor and some posted pictures on social media showing minor structural damages of walls.

In August 2014, a 5.3 magnitude earthquake hit a gold mining town near Johannesburg.

Rare earthquake damages French homes, schools and churches

Around 170 people been relocated from the western French town of La Laigne after an earthquake on Friday evening.

The quake, believed to have been between magnitude 5.2 and 5.8 was felt from Rennes in the north-west to Bordeaux in the south-west.

Homes, schools and churches were damaged, with hundreds of buildings declared uninhabitable.

Earthquakes above magnitude five are unusual in France, with the last affecting the country in November 2019.

Two people were injured in the town of Deux-Sevres following Friday's tremor.

The Charente-Maritime region just north of Bordeaux was particularly affected.

In La Laigne, the local fire service chief Didier Marcaillou warned the church had become "completely unusable" and a top government regional official said that most of the houses in the town centre were affected.

"The school will have to be closed as a precaution," Nicolas Basselier said.

One woman cried as she told local station BFMTV that she had could no longer live in her home. "I wouldn't wish this on anyone," the woman, named Christine said. "In my son's room you can fit your entire hand through the crack in the wall."

Prime Minister Élisabeth Borne described the earthquake as "unusual" and expressed her solidarity with those "who may have been worried".

"We will obviously ensure that everyone has access to rehousing," Ms Borne said.

Interior Minister Gerald Darmanin said the government would initiate an accelerated natural disaster recognition procedure to help quickly assess the structural damage to buildings.

Earthquake swarm in CamSur town may be 'precursor' to stronger tremor: Phivolcs

MANILA — An ongoing earthquake swarm in Ragay town, Camarines Sur may be an indication of a stronger tremor, the Philippine Institute of Volcanology and Seismology (Phivolcs) has warned.

An earthquake swarm is a short-lived sequence of minor to light temblors, which has no identifiable large event or main shock, according to Phivolcs.

In its Aug. 22 primer, the seismology agency said Ragay started experiencing an earthquake swarm on June 7. Over a nearly 5-day period from Saturday until Wednesday afternoon, there were 121 earthquakes recorded in the swarm, 42 of which were felt, ranging from magnitude 1.6 to 4.4, Phivolcs said Wednesday.

The swarm could persist for a few days and disappear over time, Phivolcs noted. But another possibility, it warned, is that the quakes could "be a precursor to a larger magnitude earthquake."

Phivolcs said that earthquake-induced landslides, rock falls, and other types of mass movement could occur in mountainous or hilly areas of Ragay town, home to almost 60,000 people, during the swarm.

"Liquefaction, manifested by subsidence, ground fissures, sand boils, and/or lateral spreads may affect low-lying, water-saturated, and sandy areas near water bodies," it said.

Phivolcs described Camarines Sur as a "seismically active region" due to its active faults, such as the Legaspi Lineament and offshore segments of the Philippine Fault in Ragay Gulf.

"Other local faults in close proximity might exist, and some of them could potentially be concealed by recent geologic deposits," it said. "These concealed faults have the potential to generate minor to strong earthquakes."

The earthquake swarm is not capable of triggering a tsunami, Phivolcs said, adding that it is also not an indication of volcanic activity as it is "clearly tectonic in origin."

At least 7 "significant earthquakes" had impacted Ragay town and its nearby areas since 1811, said Phivolcs, citing studies and its own records.

The most damaging, it said, was the 7.4 magnitude Ragay Gulf earthquake that occurred on March 17, 1973, which was triggered by the Guinayangan Segment of the Philippine Fault. The quake was felt at a maximum intensity of VIII (very destructive) and caused "numerous" landslides, ground rupture, liquefaction, tsunami, and structural damage, Phivolcs said.

Earthquakes are common in the Philippines, which is located in the "Pacific Ring of Fire" where many volcanic eruptions and shakings occur.
