More Greek islands closed schools Tuesday as hundreds of earthquakes ratted the Aegean Sea, while a handful of hardy tourists enjoyed having Santorini’s stunning views to themselves.

Thousands of residents and seasonal workers have left the Cycladic Islands as hundreds of quakes up to magnitude 5 were recorded in the volcanic region since Friday. Ferry and commercial flight operators added services to accommodate departures.

The quakes have caused cracks in some older building, but no injuries have been reported so far. On Tuesday, schools were shut on 13 islands, up from four the previous day. Santorini earlier canceled public events, restricted travel to the island and banned construction work in certain areas.

Efthimios Lekkas, head of the state-run Earthquake Planning and Protection Organization, said the epicenter of earthquakes in the Aegean Sea was moving northward away from Santorini, emphasizing that there was no connection to the area's dormant volcanoes.

“This may last several days or several weeks. We are not able to predict the evolution of the sequence in time,” Lekkas told state-run television.

In Santorini’s main town, Fira, the narrow, whitewashed streets along the island’s clifftops were deserted — a rare sight even in the off season — except for small pockets of tour groups, many from Asian countries.

Joseph Liu, from Guangzhou in southern China, said he had wanted to visit Santorini for years after seeing it in a documentary. He joined family and tour group members on a balcony deck typically used for high-end wedding receptions.

“This place is amazing, really beautiful. Just like I saw in the program: the mystery, the scenery,” he said. “The (group) leader told us about the earthquakes before we came so it was not a surprise.”

Retired police officer and ship worker Panagiotis Hatzigeorgiou, who has lived on Santorini for more than 30 years, said he has turned down offers to stay with relatives in Athens.

“Older residents are used to the earthquakes ... But it’s different this time. It’s not the same to have earthquakes every 2-3 minutes. The main thing is not to worry,” he said, adding with a laugh: “Now we can listen to music alone and have coffee by ourselves.”

In Athens, government officials are continuing to hold daily high-level planning and assessment meetings with briefings from island officials.



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.”
