Vale confirms seismic activity at mine prior to Sudbury earthquake
Vale confirms seismic activity at two Sudbury mines on the weekend with Earthquakes Canada recording a 2.8-magnitude earthquake on Sunday afternoon.
With all of the mining activity in the Sudbury area, residents will occasionally experience seismic activity.
The most recent earthquake happened at 2:17 p.m. Jan. 22 about 22 kilometres northeast of the city, Earthquakes Canada said.
'We can confirm that a number of seismic events occurred at Creighton Mine from 11:55 am to 12:30 pm Saturday ranging from 1.5 to 3.0 in magnitude. Seismicity was also detected at Garson Mine on Sunday at roughly 2:17 PM, measuring 3.1 in magnitude,' Jeffrey Lewis told CTV News in an email.
'No one was injured during the events and we immediately implemented our internal seismic response protocol to ensure the safety of our workforce. Operations will ramp up following inspection and as seismicity returns to background levels.'
Of the 180 community reports on the intensity of the earthquake, most recorded it as weak and light shaking with no damage.
It has been about seven months since the last time the Nickel City felt an earthquake when a 3.1-magnitude mining-related quake shook the area 13 km northeast of the city at Vale's Garson Mine at a depth of 1.5 kilometres.
'Seismicity can occur as part of mining, especially at significant depths. Our emergency response processes are in place to ensure rigorous safety protocols are followed when seismic events occur,' Lewis said.
'Residents with questions or concerns may call Vale's Community Concerns Line at 705-222-VALE.'

Five-alarm fire causes building roof to collapse in Saint-Henri
The roof of a three-storey building collapsed during a five-alarm fire in Saint-Henri, leaving the top floor exposed. More than 150 firefighters and 40 trucks were dispatched to a three-storey residential building that caught fire in the Southwest borough on Saturday. Emergency services were called around 2:54 p.m. to the intersection of Notre-Dame Street W. and Rose-de-Lima Street. The Montreal fire department (SIM) said the fire began on a third-floor balcony of the 26-unit building, which also houses businesses on the ground floor. 'Everyone was evacuated. Many were taken in by the Red Cross. About three or four families were able to arrange their own accommodation,' said SIM spokesperson Anik Vaillancourt. No injuries were reported. 'The ceiling collapsed, so the third floor is completely exposed,' she said, adding that the cause of the fire has yet to be confirmed. Firefighters extinguished the blaze around 1 a.m. on Sunday.

(Source: Essex Region Conservation Authority) The Essex Region Conservation Foundation (ERCF) has recognized two organizations at its Donor Appreciation and Awards. The ceremony recognizes those who support ERCF conservation projects and programs. The Friends of the John R. Park Homestead Inc. were given the Clifford Hatch Conservation Foundation Award. 'For decades, the Friends have been raising funds to support maintenance and restoration at the Homestead through a variety of activities,' read a news release from ERCF. 'These funds are then donated back to the Homestead for capital projects. In recent years, the Friends contributed to the sawmill roof replacement and the Monarch Butterfly exhibit.' It continued, saying in 2020 and 2021, thousands of dollars were donated for the new Conservation Centre. ADM Cares was presented the Essex Region Conservation Foundation Award for Outstanding Corporate Contribution. It recognizes significant contributions to the Foundation's fundraising goals. ADM has donated almost $100,000 to the Greenway trail system over the last two years. It also supported with five watershed cleanups across the region, removing 755 pounds of litter from the Belle River, Pike Creek, Little River, Turkey Creek, and the Canard River. 'Over and above what they are accomplishing in our corner of the world, ADM Cares is making a global impact with its philanthropy, particularly in the areas of sustainable agriculture, food security, and advancing education, said Tim Byrne, Foundation Executive Director. 'We are so grateful to both ADM Cares and the Friends of the John R. Park Homestead for their incredible investments in a future of sustainability for our region and beyond.' Supporters who have helped raised more than $650,000 for conservation projects were also thanked.

Bargain bins: People in Halifax turn to community events to save some money
With the cost of living going up and up, some people in Halifax are turning to community events and local promotions to try to save money. An organizer of an annual free clothing swap in the city's north end said she has seen more people come through the doors. "Especially people with families and children," said Judith Bonnell, who works with the Aurora North End Parish Church, which hosted the clothing swap on Saturday. "Things are extremely expensive, so it's a great way for them to come and find some good clothes." The clothing is donated by members of the public and volunteers check it for quality and sort it into piles for children, women and men, Bonnell said. Many thrift stores are getting more expensive so the people who attend the clothing swap are very appreciative for the opportunity to restock their closet for free, she said. "If they want to make a donation they can, but they don't have to," Bonnell said. Any profits from the event will help youth in the community play sports and participate in other programs, she said. Balancing the books People were lined up outside a Halifax used bookstore before it opened Saturday morning waiting to take advantage of a promotion. Customers of Agricola Street Books could fill a bag with all the discounted books they could fit for only $10. "The store opened at 10 [a.m.] and at about 9:45 there were about 20 people standing outside," said Joanne Colwell, an employee with the store. The promotion is always a hit with customers, Colwell said, but understands why more people may be eager to capitalize on offers like this as it isn't cheap being a book lover. "A new book these days is exceptionally expensive and, in a used bookstore, you have access to lots of titles," she said.
