the Longmenshan Fault -- which runs through Sichuan's mountains. That's where the 2008 Sichuan earthquake, also known as the Wenchuan earthquake, struck.

The devastating 7.9-magnitude earthquake -- near the top of the scale -- killed almost 90,000 people, and caused tremors in cities more than 900 miles away.

Since 2008, the country has invested heavily in disaster preparedness

Beijing has also directed tens of millions of dollars to developing seismic science and satellites

Mr. Sarwari said hundreds of houses had been destroyed in impoverished areas in the Qadis District, in the southern part of the province. Men, women and children were killed, many of whom had been inside the buildings.

the death toll would most likely rise significantly, because many families were still buried under the rubble.

The first quake struck just after 2 p.m. local time, east of the city of Qala-e-Naw, the capital of a province that the Taliban swept through in July on the way to capturing Kabul in August. It registered a magnitude of 4.9, according to the United States Geological Survey. The second struck about two hours later six miles away, registering a magnitude of 5.3.

For civilians in Afghanistan, earthquakes have added to the misery of living through a war that has gone on for years. There have been several earthquakes in recent weeks along Afghanistan’s eastern borders with Pakistan and Tajikistan, data from the U.S. Geological Survey show. Most were magnitude 5 or less.

"I thought at first that it was a huge bomb. But then I heard everyone around me screaming: 'Earthquake!'"

Thousands of earthquakes took place in the weeks leading up to the eruption,

Earlier this week, swarms of earthquakes rattled the peninsula, with over 3,000 quakes on Sunday alone. The strongest tremors took place around Fagradalsfjall Mountain.

Scientists attributed the earthquakes to magma intrusions, molten rock movement about a kilometer below the earth's crust. Meteorological officials first mentioned the possibility of an eruption on March 3,

The chances of an eruption escalated in recent days as magma flows concentrated around the southern portion of Mt. Fagradalsfjall

Scientists declared the mountain the most likely point should an eruption take place. Seismic activity on the peninsula decreased Friday before the mountain ultimately erupted.

It is not expected to cause havoc in air travel as did ash from the Eyjafjallajökull eruption in 2010.

No tsunami warnings, advisories, watches, or threats were issued following the earthquakes, according to the US National Oceanic and Atmospheric Administration's Tsunami Warning System.

The mayor of Tainan, William Lai, said during a visit to a funeral home that rescue efforts had entered the “third stage”.

Rescuers continued to scramble over the twisted wreckage of the building as family members waited for news of missing relatives. Lin Tong-meng said he had been waiting at the site for word of his 11- and 12-year-old nephews.

The president-elect, Tsai Ing-wen, said there needed to be a “general sorting out” of old buildings to ensure they were able to cope with earthquakes. “There needs to be a continued strengthening of their ability to deal with disasters,” she said.

The Chinese president, Xi Jinping, conveyed his condolences to the victims, the state news agency Xinhua reported late on Sunday, and repeated Beijing’s offer to provide help.

"While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip over a larger fault area," the USGS said. It added that a 7.0 magnitude quake would normally have a fault area of 50 by 20 kilometers — about 31 by 12 miles.

Although shaken often by tremors, Izmir has many older buildings that are not quake-resistant. Earthquakes often show up the poor construction quality in Turkey,

Such quakes are not uncommon in seismically active California.

You gauge the odds; that’s really the crux of choosing where to live. And you hope your political leaders have the foresight to spend money on things that may not have an immediate benefit.

In the Northwest, these are the odds: There is a 10 to 15 percent chance of a magnitude 9 earthquake happening over the next 50 years, and a 30 percent chance of a smaller, though still enormous, collision of plates

Ponce is one of several cities in the island’s southern region hit by the recent 6.4 magnitude earthquake that killed one person and caused more than an estimated $200 million in damage. More than 7,000 people remain in shelters since the quake.

But researchers say that’s not how supervolcanoes work and cast doubts for a prophetic outburst.

“When a volcano is called a supervolcano, what we really mean is it had a super eruption once, at least, in the past,”

The last V8 eruption occurred around 27,000 years ago in Taupo, New Zealand.

Scientists can’t see what is stirring below the surface of Campi Flegrei with their naked eyes, but Kilburn said the recent activity could be underground molten rock and fluids readjusting themselves. Those movements appear as earthquakes on the surface.

Out of more than 1,000 known volcanoes in the world, only about 20 are supposedly supervolcanoes. Technically, they are defined as those that register the highest on the volcanic explosivity index, which runs from V1 (nonexplosive) to V8 (colossal eruption

“But that doesn’t mean that it’s going to have other super eruptions in the future. … Very, very, very large eruptions are much, much rarer.”

Such a super eruption ejects a volume of around 1,000-cubic kilometers or more — about a thousand times bigger than Mount St. Helens (V5), which caused mudslides, fires, floods and more than 50 deaths in 1980.

Yellowstone, one of the world’s most famous supervolcanoes, measures 30 by 45 miles and welcomes millions of tourists to its park. Its largest eruption occurred 2.1 million years ago, ejecting more than 2,400 cubic kilometers of material. Like many caldera systems, the majority of Yellowstone’s eruptions have since been much smaller.

Supervolcano is “a made-up word,” said volcanologist Michael Poland, scientist in charge at the Yellowstone Volcano Observatory. “I think it’s misleading. I think it’s misapplied. I can’t stand that term. I wish it would go into the dustbin, but it’s too sexy.”

It implies an apocalyptic-like explosion, but no volcanic eruption has caused a mass extinction to our knowledge

The largest volcanic explosion in the geologic record is thought to have occurred in Toba, Indonesia, around 74,000 years ago, registering a V8 on the volcanic explosivity index. S

scientists initially speculated that the eruption almost wiped out humanity because populations declined shortly after, but archaeological evidence showed Homo sapiens farther away were thriving after the eruption.

“No explosive volcanic eruption that we know of has ever been associated with a mass extinction of plant or animal life,” said Poland, who’s also a scientist at the U.S. Geological Survey (USGS). “That’s not to say it wouldn’t be devastating or hard to live.”

Closely related is a divergence in expectations. In January, Matt Schiavenza argued perceptively in The Atlantic that one striking difference between the Charlie Hebdo massacre in Paris and a roughly contemporary suicide bombing by a 10-year-old in Nigeria was that France is not a country with a failing government or chronic conflict. As a result, attacks there are more shocking.

Many Americans hear “Paris” and think of the Eiffel Tower; they hear “Beirut” and immediately associate it with war. Yet that’s an outdated impression, as

Nor is Paris quite as calm as Americans might imagine. For example: Riots of considerable size are roughly a yearly event, especially in the banlieues; in 2005, during some of the largest riots in recent memory, three people were killed in violence triggered by police chasing three boys, but clearly emblematic of deeper tensions. This may not be the Paris that many Americans think of, but it is Paris just the same. (Both Paris and Beirut even suffered serious garbage-collection strikes this year.)

Beirut, in fact, was once known as the Paris of the Middle East. And while that name is no longer in common usage, there are still similarities between the cities. In the centers, prosperous neighborhoods offer fine dining and glamorous shopping. Farther out, less wealthy residents—many of them immigrants or children of immigrants—live in working-class districts. Paris’s suburban districts, known as banlieues, are heavily populated by Muslim immigrants.

Or should the empathy gap be attributed to an American and European press that focuses too heavily on attacks in the “West”? It’s far easier to get reporters to Paris than, say, Nairobi, though the critique is unfair to the brave reporters who report from dangerous parts of the globe year-round, not just when violence erupts. It’s a good bet that if American news organizations had devoted every resource that they dedicated to the Paris attacks to the bloodshed in Beirut instead, readers, watchers, and listeners wouldn’t have paid nearly the same amount of attention.

In an article for The Atlantic last year, Jacoba Urist reported on the findings of a study of natural disasters around the world, which found that the level of American media attention correlated with geographic proximity to the U.S. and the number of American tourists who had visited the country in question. (Urist noted that a 1976 Guatemalan earthquake with 4,000 fatalities accrued a third of the media coverage of an Italian earthquake with 1,000 deaths.) And as Faine Greenwood suggested after the Charlie Hebdo attacks, journalists and their audience alike suffer from a novelty bias. If it isn’t new—a new attack, a new place—it won’t garner the same buzz.

Founder Mark Zuckerberg has said the only reason there was no safety check-in for Beirut was that Facebook decided only after the Paris attack to deploy the feature for non-natural disasters. That aside, it makes sense that Facebook would move faster on Paris. After all, there are twice as many people in the Paris urban area as there are in all of Lebanon. Even assuming 100-percent Facebook penetration in Lebanon (not far off, probably), there are simply more Facebook users in Paris for the company to respond to.

The mountain visibly shifted during the last nuclear test, an enormous detonation that was recorded as a 6.3 magnitude earthquake in North Korea’s northeast.

Chinese scientists have already warned that further nuclear tests could cause the mountain to collapse and release the radiation from the blast.

North Korea has conducted six nuclear tests since 2006

After the latest nuclear test, on Sept. 3, Kim Jong Un’s regime claimed that it had set off a hydrogen bomb and that it had been a “perfect success.”

The regime is known for brazen exaggeration, but analysts and many government officials said the size of the earthquake the test generated suggested that North Korea had detonated a thermonuclear device at least 17 times the size of the American bomb dropped on Hiroshima in 1945.

Since that day, there have been three much smaller quakes at the site, in the 2 to 3 magnitude range, each of them setting fears that North Korea had conducted another nuclear test that had perhaps gone wrong. But they all turned out to be natural.

Because if the hypothesis is right, it will soon start to dawn on people that our mistake was not insufficient reverence for scientists, or inadequate respect for expertise, or not enough censorship on Facebook. It was a failure to think critically about all of the above, to understand that there is no such thing as absolute expertise

There was a time when the Covid pandemic seemed to confirm so many of our assumptions. It cast down the people we regarded as villains. It raised up those we thought were heroes. It prospered people who could shift easily to working from home even as it problematized the lives of those Trump voters living in the old economy.

But these days the consensus doesn’t consense quite as well as it used to. Now the media is filled with disturbing stories suggesting that Covid might have come — not from “populism” at all, but from a laboratory screw-up in Wuhan, China. You can feel the moral convulsions beginning as the question sets in: What if science itself is in some way culpable for all this?

In the years since (and for complicated reasons), liberal leaders have labored to remake themselves into defenders of professional rectitude and established legitimacy in nearly every field. In reaction to the fool Trump, liberalism made a sort of cult out of science, expertise, the university system, executive-branch “norms,” the “intelligence community,” the State Department, NGOs, the legacy news media, and the hierarchy of credentialed achievement in general.

The news media, in its zealous policing of the boundaries of the permissible, insisted that Russiagate was ever so true but that the lab-leak hypothesis was false false false, and woe unto anyone who dared disagree. Reporters gulped down whatever line was most flattering to the experts they were quoting and then insisted that it was 100% right and absolutely incontrovertible — that anything else was only unhinged Trumpist folly, that democracy dies when unbelievers get to speak, and so on.
