Quake Damages Ancient Citadel in Syria’s Aleppo

Several of Syria's archaeological sites including a famed citadel in the northern city of Aleppo were damaged in a deadly pre-dawn earthquake Monday, the country's antiquities authority said.

"Parts of the Ottoman mill inside the citadel" of Aleppo have collapsed, while "sections of the northeastern defensive walls have cracked and fallen", Syria's Directorate-General of Antiquities and Museums said in a statement.

Parts of the dome of the minaret of the Ayyubid mosque inside the citadel fell off, while the entrance to the fort has been damaged, "including the entrance to the Mamluk tower", it added, publishing photos of the site on its Facebook page.

Hundreds of people were killed across Syria as buildings collapsed after the 7.8 magnitude earthquake struck neighboring Türkiye, state media and rescuers said.

At least 156 people died in Aleppo province alone and 507 were injured when 46 buildings collapsed, the official news agency SANA had said, quoting an official.

The city of Aleppo is renowned for its ancient citadel, its UNESCO-listed historic center and its centuries-old covered markets.

Aleppo was Syria's pre-war commercial hub and considered one of the world's longest continuously inhabited cities, boasting markets, mosques, caravanserais, and public baths, but a brutal siege imposed on opposition factions left it disfigured.

Even before the earthquake, buildings in Aleppo often collapsed due to poor infrastructure after more than a decade of war and little oversight to ensure the safety of new construction projects.

In Hama province, archaeological surveys found that "some buildings inside the ancient Al-Marqab Castle" in the city of Baniyas had been damaged, while parts of the fortifications and a tower had fallen, the antiquities body said.

In Tartus province, part of a rocky cliff fell in the vicinity of the Qadmus castle, and residential buildings on the site collapsed, it added.

Expert teams were reportedly assessing the damage, and whether the earthquake had affected the ancient city of Palmyra.

The pre-dawn quake hit near Gaziantep in southeastern Türkiye at a depth of about 18 kilometers (11 miles), the US Geological Survey said.

Tremors were also felt in Lebanon and Cyprus, AFP correspondents said.



These Canadian Rocks May Be the Oldest on Earth

Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada.

The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks — plains of streaked gray stone on the eastern shore of Hudson Bay in Quebec. But researchers disagree on exactly how old they are.

Work from two decades ago suggested the rocks could be 4.3 billion years old, placing them in the earliest period of Earth's history. But other scientists using a different dating method contested the finding, arguing that long-ago contaminants were skewing the rocks' age and that they were actually slightly younger at 3.8 billion years old.

In the new study, researchers sampled a different section of rock from the belt and estimated its age using the previous two dating techniques — measuring how one radioactive element decays into another over time. The result: The rocks were about 4.16 billion years old.

The different methods "gave exactly the same age,” said study author Jonathan O'Neil with the University of Ottawa.

The new research was published Thursday in the journal Science.

Earth formed about 4.5 billion years ago from a collapsing cloud of dust and gas soon after the solar system existed. Primordial rocks often get melted and recycled by Earth's moving tectonic plates, making them extremely rare on the surface today. Scientists have uncovered 4 billion-year-old rocks from another formation in Canada called the Acasta Gneiss Complex, but the Nuvvuagittuq rocks could be even older.

Studying rocks from Earth's earliest history could give a glimpse into how the planet may have looked — how its roiling magma oceans gave way to tectonic plates — and even how life got started.

“To have a sample of what was going on on Earth way back then is really valuable,” said Mark Reagan with the University of Iowa, who studies volcanic rocks and lava and was not involved with the new study.

The rock formation is on tribal Inukjuak lands and the local Inuit community has temporarily restricted scientists from taking samples from the site due to damage from previous visits.

After some geologists visited the site, large chunks of rock were missing and the community noticed pieces for sale online, said Tommy Palliser, who manages the land with the Pituvik Landholding Corp. The Inuit community wants to work with scientists to set up a provincial park that would protect the land while allowing researchers to study it.

“There's a lot of interest for these rocks, which we understand,” said Palliser, a member of the community. “We just don't want any more damage.”
