What to know about earthquake early warning systems

As earthquakes struck from California to Venezuela to Japan, millions of people received warnings on their mobile phones, providing critical seconds to seek protection.

Venezuela was struck with a pair of deadly earthquakes Wednesday evening and Thursday morning that brought significant shaking to the northern coast of Japan. Earlier in the week residents in the U.S. state of California experienced a moderate earthquake, and at the start of June, 37 people in the Philippines died in a quake near Mindanao.

Many nations have developed systems for alerting people seconds before shaking begins. Even in countries like Venezuela that do not have such systems, Google Android Earthquake Alerts can send warnings.

B.C. government marks 5 years since heat dome killed hundreds

VANCOUVER - A stifling heat dome that sat over much of British Columbia five years ago is being remembered by the provincial health officer as traumatic for people who lost loved ones and overwhelming for those trying to care for those affected. 

More than 600 people died during the first provincewide heat dome in 2021, but Dr. Bonnie Henry says it will not be the last such event. 

Henry says in a statement issued Thursday that most of the people who died during the period between June 25 and July 1 lived alone and weren't able to keep cool inside their homes. 

She says her thoughts are with those who live with trauma from the event and she knows of the "tremendous effect" on people who lost loved ones and on the first responders and health-care workers who were overwhelmed with people needing help. 

The 2 earthquakes that struck Venezuela are known as a ‘doublet.’ Here’s how they happen

SAN JUAN, Puerto Rico (AP) — The two powerful earthquakes that struck Venezuela’s northern coast, killing more than 180 people, were an event known as a “doublet.”

Doublet earthquakes happen when a pair of similar-sized quakes hit close in location and time, according to the U.S. Geological Survey. On Wednesday evening, a 7.2 magnitude quake hit first, followed by a magnitude 7.5 just 39 seconds later.

The deadly one-two punch toppled buildings in Venezuela’s capital, Caracas and beyond. Some 1,500 people were injured and thousands were reported missing. The coastal region of La Guaira, which is north of Caracas, experienced some of the heaviest damage and casualties, officials said.

How rare are doublets?

Grade 7 students learn about environment in Seine River cleanup

On a rainy Wednesday morning, Grade 7 students from École Lacerte traded their classroom desks for rubber boots as they headed out along the Seine River to help plant native shrubs, test water quality, and clean up the riverbank.

JJ Swidersky, one of about 40 students taking part in the work, says protecting the environment is important to him and his classmates.

“Planting the trees, planting the shrubs,” Swidersky said when asked about his favourite part of the effort. “Just trying to keep the river clean, trying to keep it as clean as we possibly can.”

The planting Swidersky is referring to is part of the Niakwa Trail Rain Garden, which is located next to the St. Anne’s Superstore.

When a rip current sucks you out to sea, try not to panic

SAN DIEGO (AP) — To someone who is getting sucked out to sea by a rip current, “Don’t panic!” may be difficult to heed, even if that’s exactly what you should do. But lifeguards say to not only relax but flip over and float out of the danger.

Rip currents are one of the coast’s greatest dangers and account for the most beach rescues every year. About 100 people drown from rip currents along U.S. beaches each year, according to the United States Lifesaving Association. And more than 80% of beach rescues annually involve rip currents.

Already this year, there have been at least 21 people killed from rip currents in U.S. waters, according to the National Weather Service.

Here are some things to know about rip currents:

Archaeologists find huge Viking textile production site in Denmark

SØFTEN, Denmark (AP) — Archaeologists have discovered a huge Viking Age textile production site in Denmark that dates back more than 1,000 years and underlines the sophistication of Viking society.

Experts from the Moesgaard Museum said this week that the sprawling 100,000-square-meter (more than 1 million-square-foot) site features an area for processing flax as well as more than 80 pit houses — semi-buried huts that were used as workshops and dwellings in Viking times.

It's located in Søften, 10 kilometers (6 miles) north of Denmark’s second-largest city, Aarhus, on the Jutland peninsula. The site dates back to the late Iron Age and early Viking Age, sometime between A.D. 600 and 950.

Archaeologist Liv Stidsing Reher-Langberg, who led the 10-month dig, said that “we have a clear focus on textile production, which makes this settlement different from other kinds of settlements of this period.”

COVID-19 vaccine study that was blocked from CDC journal is published elsewhere

NEW YORK (AP) — A study on COVID-19 vaccine effectiveness has finally been published after being blocked from a government health journal.

The vaccine was found to be about 55% effective against COVID-19-associated hospitalizations, and reduced COVID-19-related trips to emergency departments and urgent care clinics by 50%, according to the study published Tuesday by JAMA Network Open.

The findings are not particularly surprising: Researchers have repeatedly found that COVID-19 vaccines work. But the paper drew public attention after Trump administration political appointees decided not to run it in a Centers for Disease Control and Prevention publication.

They argued that the study's design was too vulnerable to false assumptions that could produce flawed results. But many public health researchers maintain it's a reliable design that's been used for decades and offers the best way to understand how well a vaccine is working currently.

Wanted: The Teton Range’s few remaining mountain goats

Every now and then, a hiker, climber or biologist lays eyes on a mountain goat in the nooks and crannies of the mighty Teton Range.

There’s a good likelihood that the unwanted, nonnative animal doesn’t survive long after the authorities pinpoint its presence. That’s because the National Park Service is now removing all mountain goats that survived an intensive three-year effort to rid the Tetons of the species.

A striking white alpine species, mountain goats are being targeted by gunners because they’re seen as a threat to native bighorn sheep. Mountain goats are more aggressive, overlap habitat and can also spread diseases that can be catastrophic.

“We have seen mountain goats — and we have removed those when we have found them,” Grand Teton National Park Superintendent Chip Jenkins told WyoFile in February. “We hire a private contractor who does the flying in terms of doing the survey, and we hire a private contractor who does the removal.”

How a heat dome is formed and why experts blame one for Europe’s baking temperatures

Europe is sizzling under an early heat wave this week, with millions of people experiencing extremely high temperatures, and experts say a phenomenon known as a heat dome is to blame. Here's what to know.

A soothing cup of herbal tea can begin in your garden

Drink a fragrant cup of herbal tea, and the intoxicating scent of steeped herbs might calm your mind before you even take a sip. Even better is when they come from your own backyard herb garden.

Mine includes several ingredients for my daily cup, and they’re all easy to grow and prepare.

Herbal teas are distinct from true teas — such as black or green — which comes from the leaves of the Camellia sinensis plant. (You can grow that in your garden, too.) Brew herbal teas with either freshly harvested or dried herbs.

Either way, settling in with a cup of homegrown herbal tea — hot or iced — can be a relaxing ritual.

Confronting the scourge of polio

From 1928 to 1953, polio epidemics occurred in Manitoba every three to five years. The pain for the young victims was often excruciating. The vast majority of children recovered, yet many experienced lifelong disabilities from the disease.

Significance of soil, water management

The day six inches of rain fell one early July afternoon is etched in my memories of growing up on a southern Manitoba grain farm in the mid-1960s.

While we merrily played in the overflowing ditches, our parents watched helplessly as the surrounding fields went under. Within days, it became clear that the crop of 1966 was a write-off.

Rather than watching it rot, Dad went to work retrofitting the family van so all six of us could sleep in it, and we set off on an extended camping trip to the mountains. We didn’t see much of him that winter, however. He commuted 50 kilometres to Winnipeg with the grain truck to make department store deliveries to help pay the bills.

Excess rainfall of that magnitude happened once in their 40 years of farming, but it informed lasting changes to how fields were drained and soil was managed.

Opposition forms to First Nation’s bid for wind farm

A group of residents in southwestern Manitoba is concerned a proposed wind farm could impact their way of life.

RM of Lorne resident Bill Harrison said the Swan Lake First Nation proposal to build 30 to 35 wind turbines would disturb day-to-day life and have adverse environmental and economical impacts.

“Agriculture is a major consideration in Manitoba, it’s a major provider of food. The wind towers, they take up two to three acres a piece just to install. And then the service roads and the actual spot where the towers are planted is more too,” Harrison said Thursday.

The RM of Lorne, located 145 kilometres southwest of Winnipeg, has a wind farm in the St. Leon area that was built in 2006 and expanded in 2011. The 200 square kilometre wind farm has 73 turbines that generate the energy needs of more than 40,000 homes, according to the province.

National Science Foundation reverses decision to dismantle oceans-monitoring network after outcry

The U.S. National Science Foundation on Thursday reversed a decision to dismantle a sprawling ocean monitoring network after vigorous objections from Democratic lawmakers and scientists who rely on it to track everything from ocean circulation to extreme weather.

FDA panel backs first-of-its-kind flu vaccine using mRNA technology

WASHINGTON (AP) — A new kind of flu vaccine moved a step closer to the U.S. market Thursday as federal health advisers recommended approval of the first made with the same mRNA technology that was key to ending the COVID-19 pandemic.

The Food and Drug Administration is evaluating Moderna's new shot, dubbed mFlusiva, for older Americans ahead of the winter flu season. Moderna is seeking full approval for the vaccine's use in people ages 50 to 64 — along with authorization for use in those 65 and older while it conducts additional testing.

The FDA's independent advisory committee evaluated Moderna's studies of the vaccine and voted unanimously that its benefits appear to outweigh any risks for both age groups. The FDA will consider that recommendation in making a final decision by early August.

Tens of thousands of Americans die from influenza every year, and older adults are among the most vulnerable. There are various types of flu vaccines already available in the U.S., including three specifically recommended for people 65 and older. But vaccines made with the Nobel Prize-winning mRNA technology are faster to manufacture than other types — something experts say might help if the shape-shifting flu virus mutates in a way that requires suddenly brewing new doses to match.

An ancient oak tree said to have sheltered legendary Robin Hood has died

LONDON (AP) — A massive ancient oak tree linked to the legend of Robin Hood may have been loved to death.

The 1,200-year-old Major Oak in Sherwood Forest is believed to have died after it didn’t sprout leaves this spring, the Royal Society for the Protection of Birds said Thursday.

Visitors over the past two centuries who viewed the tree's gnarled limbs and sprawling canopy in Nottingham compressed the soil, making it difficult for rain to reach its roots, the conservation group said.

The forest has been under threat for years and the tree had been rumored to have died in the past — only to have the group confirm it was still alive.

Archaeology team unearths ‘prototype’ of world-famous Stonehenge monument just a few miles away

LONDON (AP) — Archaeologists revealed Thursday that they have discovered a structure near the prehistoric stone circle of Stonehenge in southern England that may have served as a “prototype” for the 5,000-year-old Neolithic monument.

A team from the British firm Wessex Archaeology said the structure would have consisted of two wooden poles 120 meters (394 feet) apart and aligned to point directly at the rising sun during the summer solstice and the setting sun at the winter solstice.

Researchers said the discovery predated Stonehenge by around 500 years.

The team was led by archaeologist Phil Harding, who is well known in the U.K. through his many years of excavations for Channel 4 TV series “Time Team.”

‘Electrical non-compliances’ found at B.C. waterpark where kids were burned

CULTUS LAKE - The agency that oversees safety at B.C. amusement parks says investigators have found "electrical non compliances" at Cultus Lake Waterpark where a group of 12 schoolchildren suffered electrical burns on Monday.

Technical Safety BC, which is leading the investigation into what went wrong at the park, said in a statement on Wednesday that the finding means the park in the Fraser Valley will be shut until the problems are fixed and there is no timeline for reopening.

The regulator said its safety officers are “conducting a thorough assessment” at the park where the group suffered electrical burns requiring hospitalization.

The waterpark posted a statement on its website on Tuesday that said it was "fully co-operating with all authorities as they complete" their investigation.

Manitoba’s role in a distant Ebola outbreak

Across parts of Central and East Africa, a familiar threat has returned. The Bundibugyo strain of Ebola, one of the rarer and generally less fatal variants of the virus, has emerged again in the Democratic Republic of the Congo and Uganda.

Weighing profits against transforming ‘beautiful country’ of wind-turbine proposal south of Brandon

A major wind-turbine project has been proposed for the Carroll area south of Brandon. Innergex Renewable Energy has made preliminary agreements with landowners on roughly 12,000 acres and is looking to install 30 to 35 turbines.

Storm insurance claims could set Manitoba record

Manitoba is on pace to set a record for insurance claims related to this week’s storms.

Insurance brokers have been inundated with calls to assess and process claims for flooded basements and properties. Local insurer ONE Insurance said it has received more than 700 claims and expects to issue millions of dollars to its clients.

“It is definitely the single largest event that we’ve experienced in our organization,” said interim CEO Rey Girardin.

Residents in the RM of Rockwood, including in Stonewall and Balmoral, have submitted the most claims, he said.
