The coronavirus pandemic is making Earth vibrate less – CTV News

Published

 on


Once-crowded city streets are now empty. Highway traffic has slowed to a minimum. And fewer and fewer people can be found milling about outside.

Global containment measures to combat the spread of the coronavirus have seemingly made the world much quieter. Scientists are noticing it, too.

Around the world, seismologists are observing a lot less ambient seismic noise — meaning, the vibrations generated by cars, trains, buses and people going about their daily lives. And in the absence of that noise, Earth’s upper crust is moving just a little less.

Thomas Lecocq, a geologist and seismologist at the Royal Observatory in Belgium, first pointed out this phenomenon in Brussels.

Brussels is seeing about a 30 per cent to 50 per cent reduction in ambient seismic noise since mid-March, around the time the country started implementing school and business closures and other social distancing measures, according to Lecocq. That noise level is on par with what seismologists would see on Christmas Day, he said.

LESS NOISE MEANS SEISMOLOGISTS CAN DETECT SMALLER EVENTS 

The reduction in noise has had a particularly interesting effect in Brussels: Lecocq and other seismologists are able to detect smaller earthquakes and other seismic events that certain seismic stations wouldn’t have registered.

Take, for example, the seismic station in Brussels. In normal times, Lecocq said, it’s “basically useless.”

Seismic stations are typically set up outside urban areas, because the reduced human noise makes it easier to pick up on subtle vibrations in the ground. The one in Brussels, however, was built more than a century ago and the city has since expanded around it.

The daily hum of city life means that the station in Brussels wouldn’t typically pick up on smaller seismic events. Seismologists would instead rely on a separate borehole station, which uses a pipe deep in the ground to monitor seismic activity.

“But for the moment, because of the city’s quietness, it’s almost as good as the one on the bottom,” Lecocq said.

Seismologists in other cities are seeing similar effects in their own cities.

Paula Koelemeijer posted a graph on Twitter showing how noise in West London has been affected, with drops in the period after schools and social venues in the United Kingdom closed and again after a government lockdown was announced.

Celeste Labedz, a PhD student at the California Institute of Technology, posted a graph showing an especially stark drop in Los Angeles.

Still, seismologists say the reduction in noise is a sobering reminder of a virus that has sickened more than one million people, killed tens of thousands and brought the normal rhythms of life to a halt.

IT SHOWS PEOPLE ARE HEEDING LOCKDOWN RULES

Lecocq said the graphs charting human noise are evidence that people are listening to authorities’ warnings to stay inside and minimize outside activity as much as possible.

“From the seismological point of view, we can motivate people to say, ‘OK look, people. You feel like you’re alone at home, but we can tell you that everyone is home. Everyone is doing the same. Everyone is respecting the rules,'” he said.

The data can also be used to identify where containment measures might not be as effective, said Raphael De Plaen, a postdoctoral researcher at Universidad Nacional Autónoma de México.

“That could be used in the future by decision makers to figure out, ‘OK, we’re not doing things right. We need to work on that and make sure that people respect that because this is in the interest of everyone.'”

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
