Nearly 1,400 Aftershocks Rattle Alaska After 7.0 Earthquake

Roughly 1,400 aftershocks have followed after Friday's monster 7.0 magnitude earthquake struck near Anchorage, Alaska, Anchorage Daily News reported.

The aftershocks all surrounded the original temblor that was centered about 7 miles north of Alaska's largest city.


Of the 1,400 aftershocks recorded since Sunday, 593 measured greater than a magnitude 2.0, 17 were at least a 4.0, and five were at least a 5.0, the report said.

In all, up to 2,200 aftershocks greater than a magnitude 3 are possible, according to a post from Ian Dickson of the Alaska Earthquake Center on Sunday, citing the U.S. Geological Survey aftershock forecast.

Friday's quake was described by state seismologist Mike West as the "most significant" to strike the city since the magnitude 9.2 Great Alaska Earthquake of 1964—the most powerful ever recorded in the U.S. It was also the largest since the 7.1 that struck near Anchorage in 2016.

"I'm not aware of large-scale building collapses, but I think it's safe to say there are thousands of homes and businesses and buildings that were damaged in some fashion, be it a deck that slid downhill, a cracked foundation, a gas line disconnected from the house," he said during a Facebook Live interview, as quoted by USA TODAY.

Miraculously, no deaths were reported. However, "hospitals reported receiving two patients with life-threatening injuries and dozens of less serious cases, including broken bones, injuries from falls, and lacerations from broken glass," Dickson wrote.

Although the seismic activity has been nerve-racking to the area's residents, earthquakes are not new to Southcentral Alaska. In the last century, 14 other earthquakes greater than a magnitude 6.0 have occurred within 150 kilometers (approximately 93 miles) of Friday's temblor, according to USGS. The state itself averages about 40,000 earthquakes per year.

USGS reported that the Nov. 30 quake was "the result of normal faulting at a depth of about 40 km."

Experts said more aftershocks will continue in the area but will start to dwindle in the coming weeks.

"You can expect earthquakes in magnitude 5 or 4 to continue for the next couple of weeks, and as time goes on it tapers off," Rafael Abreu, a geophysicist with the U.S. Geological Survey Earthquake Science Center, told the Anchorage Daily News.

Alaska Gov. Bill Walker issued a disaster declaration. President Trump has approved an emergency declaration for the state.

More information about the aftershocks can be accessed here through the Alaska Earthquake Center.

For a Happier, Healthier World, Live Modestly

By Marlene Cimons

Gibran Vita makes every effort to get rid of the dispensable. He lives in a small home and wears extra layers indoors to cut his heating bills. He eats and drinks in moderation. He spends his leisure time in "contemplation," volunteering or working on art projects. "I like to think more like a gatherer, that is, 'what do I have?' instead of 'what do I want?'" he said.

As Miami Battles Sea-Level Rise, This Artist Makes Waves With His 'Underwater Homeowners Association'

By Patrick Rogers

Miami artist Xavier Cortada lives in a house that stands at six feet above sea level. The Episcopal church down the road is 11 feet above the waterline, and the home of his neighbor, a dentist, has an elevation of 13 feet. If what climate scientists predict about rising sea levels comes true, the Atlantic Ocean could rise two to three feet by the time Cortada pays off his 30-year mortgage. As the polar ice caps melt, the sea is inching ever closer to the land he hopes one day to pass on to the next generation, in the city he has called home since the age of three.

How to Ferment Vegetables in Three Easy Steps

By Brian Barth

A mason jar packed with cultured or fermented vegetables at your local urban provisions shop will likely set you back $10 to $15. Given that the time and materials involved are no more than five minutes and $2, respectively, one imagines that the makers of cultured vegetables have spent eight years training with fermentation masters in some stone-age village, or that they've mortgaged their house to pay for high-end fermenting equipment to ensure that the dilly beans come out tasting properly pickled.

Norway to Ban Deforestation-Linked Palm Oil Biofuels in Historic Vote

The Norwegian parliament voted this week to make Norway the world's first country to bar its biofuel industry from importing deforestation-linked palm oil starting in 2020, The Independent reported.

Environmentalists celebrated the move as a victory for rainforests, the climate and endangered species such as orangutans that have lost their habitats due to palm oil production in Indonesia and Malaysia. It also sets a major precedent for other nations.

"My son was only three years old when he first suffered from asthma," she said. Like most kids, he rode a diesel school bus. Some afternoons he arrived home struggling to breathe.

Hemp May Soon Be Federally Legal, But Many Will Be Barred From Growing It

By Dan Nosowitz

Senate majority leader Mitch McConnell has, perhaps unexpectedly to those who find themselves agreeing with only this one position of his, been a major force for legalizing industrial hemp. Industrial hemp differs from marijuana in that it's bred specifically to have extremely low concentrations of THC, the primary psychoactive chemical in marijuana; smoke industrial hemp all you want, it'll just give you sore lungs.
